2000 Ford F-250 Super Duty Problems and Solutions

alltork · January 2004

Ive got an 1994 f 250 4x4 with the turbo diesel(not the power stroke)Ive changed all the fluids to synthetic along with all the filters. My question is whats the proper way to start in cold weather without the block heater. The owners manual says to depress the gas while cranking when below freezing,but I'm not sure that this helps Any ideas or suggestions would be great Thanks

wpalkowski · January 2004

How cold are we talking? I thought that Fords could start at least down to -20 without the block heater, that is if all of the other components are good Is your battery in tip-top shape? Make sure your glow plugs are working properly. The Glow Plug Relay can be a weak link - contacts get tired and won't carry optimal current to the glow plugs and they won't heat things up well.
When you go to start, the GP light goes out after about 15-20 sec but the GPR is on for nearly two minutes. Wait another 45 sec after the light goes out before turning her over. Cycle the glow plugs again before cranking if it is really cold.
The synthetic lubricants are great, they give you a much lower flow/pour temperature and much less resistance to cranking the engine. Depending on where you live and whether they have winter blend diesel, you might want to add an anti-gel formula to your fuel. There are several on the market, some of the names are PowerService (available at most Truck Stops) and Stanadyne.

alltork · January 2004

Thanks for the info. The temps are around 0 to 20 above right know,does it help to give it any pedal before or while cranking?Ill have to get the gpr checked I did notice that after it starts the volt meter jumps back and forth is this related to the gpr it only does this for about 1 minute Thanks again

mullins87 · January 2004

The jumping in the voltmeter most likely is the glow plugs cycling on and off. My gauge doesn't move, but I can tell by how the headlights dim and then get brighter. I wouldn't give it any pedal at startup. Why? Well, there is an idle validation switch on the accelerator pedal. The pcm will add as much fuel as is necessary, up to a point, to maintain idle as long as that switch is activated. I don't know any specific numbers nor am I knowledgable enough to explain the fueling curve. However, I'd bet the pcm is already dumping a considerable amount of fuel in the cylinders anyway.

We have a 2003 F150 S/C Heritage Edition. We purchased it in 3/03. At about 7,000 miles it started running rough ( as if it is running out of gas and the smell coming out of the tail pipe is horrible)when stopped at a red light or while stuck in traffic. At first it happened maybe once a week. Now it is doing it every day. We have had it a 2 different dealerships and now it is at the dealership waiting for a Ford Field Engineer to look at it. The dealerships can not find anything wrong with it. Once the dealership told us it was the transmission. But while at the shop the same time they came up with #8 spark plug and coil which they replaced. Two days later it did it again. Any suggestions? They have put the "black box" on it but the computer does not show anything. Also have been told that it is "normal" engine vibration through the motor mounts. It that is normal why doesn;t it do it all the time?

todd1965 · January 2004

I have a 2003 Ford SC 4X4, if I install this chip to increase horse power and torque will this void my For warranty.

mac24 · January 2004

If the chip is still fitted, or there's evidence of it having been there, at the time of your claim, the answer is yes it can be. However, the warranty can only be voided on items that can be affected by the chip i.e. engine/drivetrain/electrics. Unrelated items like paintwork, glass, upholstery, etc., (assuming it wasn't damaged by an electrical fire caused by the chip!).

Ultimately though, it's your relationship with your dealer that will decide the issue.

stephjos · January 2004

I am looking at buying a 1998 F150 XL V6 4.2L and my mechanic told me that there is a leak in either the valve cover or head gasket does anyone have and idea which would be more common in this model? he has a feeling that it is the valve cover but i am still conserned about the head gasket leak? any other conserns that might help my cause it has 56,000 miles.

vidtech · January 2004

what are you leaking oil,vacuum???

wijoco · January 2004

The 97/98 4.2s had problems with the intake, timing cover and head gaskets leaking. Yours may have any combination of leaks. I wouldn't purchase it unless the seller will confirm the leak and will give you a sizeable discount to cover the cost of a repair. If he pretends he doesn't know about the leak or it's no big deal, just walk away.

stephjos · January 2004

is there anyway i can confirm that it is a head gasket? it is the perfect truck and i dont want to let it go with out making sure of the problem. Is this a major problem that it will have to be fixed soon? does anyone have a idea of what it would cost to fix a head gasket?
thanks!
Joe

mac24 · January 2004

If you're serious about buying this truck you've reached the point where you need to pay a reputable auto shop, or tech, to check it out.

nml4life · January 2004

I just bought a used F150 Crew Cab 4x4 and the transmission is slipping when kicking into overdrive. It drives perfect when the overdrive is turned off. However if I turn it back on say at 50 mph, the RPM's rev up and then finally engage. I believe it has a 4R70W tranny in it. I have heard that since the overdrive is electronically controlled it could be this but I wanted to find out before I spend $1k + dollars to get it fixed.

porno4parrotts · February 2004

I just thought I would post my problems with my last truck.
At 35K miles my tranny started to slip. By the time I hit 50K I was told by the dealer that tranny number 6 had to be installed.
I had had enough!
I contacted the owner of Sam Pack's Ford in Dallas and got old Sam on the phone.
Now you need to understand I had done business with these guys for 12 years.
I asked Sam to make me deal on a new truck since I was finished with this one.
He was not willing to make any cost concessions on a new truck. He almost gave me the idea he did not want my truck either.
I traded it for new 03 Silverado LT. So far so good!
I will never purchase another Ford as long as I am alive.

todd1965 · February 2004

I think that some Ford dealerships have gotten fat and lazy and not respect the customers. Sorry you had to leave the Ford family but good luck with your new truck,

geodanvers · February 2004

I have a 1999 f150 5.4 with 47000 miles on the engine.The Head gasket blew It was -12 degree and the enging came up limping it pays to buy the extra insurance when you buy a FORD

jrc346 · February 2004

I believe that engine should be covered under one of Fords secret warranties. This is a very well known problem that comes from a defect in the machining the heads on the 5.4 mostly in 1999.

Here is the TSB: #03-6-2
MAR 03 Engine - Oil Leak From R/H Cylinder Head Gasket

If left long enough, I am sure this would cause a complete failure.

When you say "extra insurance" does that mean that you have an extended warranty? If so thats great, but in most cases that engine would have been replaced for free anyway. Be confident that your new/rebuilt 5.4 will be trouble free, as the defect has been corrected.

sam818 · February 2004

I have a 2004 Lariat SuperCrew. After just 700 miles, I have a squeak which appears to be coming from the entire rear window surround. It squeaks only over bumps, almost as though the cab is flexing, and the window frame (which appears to be one moulded piece)is rigid. Putting hand pressure on the frame when it squeaks does not stop the problem, so I suspect it is a large flexing over a large area.
Anyone had this problem? What should I do? Does Ford have a contact who would be interested in this or can help?
Given the published rigidity of the new frame, I am suprised, however, this seems to be a flexing of the "cab"... so was the same attention paid to this?

wijoco · February 2004

Could simple be a squeak around the moulding mounting surface of the window. I wouldn't suspect that the cab frame itself is flexing. Only solution is to take it back to the dealer until you're satisfied.

sam818 · February 2004

.....I would imagine that the glass is less likely to flex than the cab itself. I don't think there is any way to make the cab more rigid after the fact..that would have to be addressed at the engineering level.
I have since found, on other F150 web sites, that this is a widespread defect. The fix seems to be taking the window frame out and inserting some extra foam stripping. It's a bummer, because the truck is otherwise very stiff.

spoom · February 2004

I needed a truck that could pull a 5000lb trailer and since my first (and last) GMC experience left me incapable of ever giving them a dime again I was left between Ford and Toyota. I'd had Toyotas since '76 and Fords before that. The '03 5.4 Flareside Supercab I eventually got came in at about $2k less than the Toy due to incentives, etc. After about 3 months of ownership I am surprised how bad the wind noise is at highway speeds with a crosswind. It sounds like the window is cracked open but it isn't, and switches from side to side depending which side the wind is coming from. Is this common with this body style? The other thing I noticed is that I am spoiled from my "97 Jimmy SLT's dual sun visors with the slide out extensions. The ones on the Ford PU leave a huge open area in the center of the windshield that is more than just a little annoying. Do the Lariat models have something better? I can give up my super dooper 6 way power seat, but driving into the sun is almost impossible. Any thoughts?

busman01 · February 2004

1. I too had the wind noise issue in my supercab. Turns out the back door was not closed completely. Shut it well and the wind issue should be resolved.
2. I have the Lariat and I too long for extended visors.

jrc346 · February 2004

These trucks are supposed to be pretty quiet. If you don't care for the noise, take it back to your dealer and have them fix it. The least they could do is replace the door seal:)

bpet · February 2004

Hi, I haven't read the boards in a while but I need some help. I have a 2000 F-250 Superduty with the ESOF option. Right now my truck has just over 20,000 miles on it. I have had many problems with my automatic hubs. The original set was replaced when the truck was very new because you couldn't turn them without a set of pliers. The second set did the same thing and was replaced in March of 2001. These first two sets Ford replaced without any problem and at no cost to me. The second set was supposed to be an updated version that was to correct the problems form the past. Until now they have always worked when you turned the switch to engage them, they just would get dirty and it would become very hard to turn them from lock to auto. Now again they won't turn without pliers but I can't get them to engage in the auto position. If I set them to lock everything works fine. I brought the truck in to Ford yesterday and they said one hub is bad and I should replace both. The problem is they want me to pay (over $600) for the new hubs. They tell me all of these hubs are having major problems and Ford is not willing to do much about it. Since I'm on my third set I have to think the hubs are junk and since Ford put them out there they should stand behind them no matter what. I want to fight this refusal by Ford to replace my hubs in any way I can and I would like to hear from anyone that has had the same problem. What should I do?

marsha7 · February 2004

in who-knows how many car sites, it appears that the wife wants a pickup truck...anything that makes HER happy, makes ME happy, for all you married folks out there...considering a used (2003?) F150 King Ranch, which do not seem to be too common, and some local salesfolk do not seem to know what is important to me...yes, color is important, but maybe some King Ranch owners may quick answer some questions...

1. the King Ranch is a true four door with pillar between the doors, I believe...is that true?

2. the seats...I must have manual or power lumbar support for both front passenger and driver...GMC Sierra has 10 way power seats for pass and driver, and also power lumbar support for both...does the King Ranch, or any model of the F150?

3. can the KR be had with a short bed so the entire vehicle does not cross two counties?

4. does the 2003 come with adjustable pedals and a 5.4L engine?

Thanks...Bob

tzash · February 2004

I have a 2001 F-150 Lariat 4x4 5.4 with 48,000 Mi.
It has been approx 5,000 miles since the last oil change. The drain plug is tight, and the motor never seemed to burn oil. Friday evening the motor suffered a catastrophic failure. As I was driving down I-95, the "service engine soon" light came on, the engine began to lose power and the oil pressure dropped. Before I could pull off on the shoulder and shut it off, I heard a short "screech" (Obviously a seizure).

Not fair considering that I just bought out the lease and haven't even made the 1st payment yet!

Anyway.- My mechanic has told me that there is a company he deals with, that can get me a new "0" milege motor with all of the updates needed according to the TSB"s issued to the dealers, for about $3,000 (Motor only). It also comes with a 2 year 40,000 mile warranty.

I really like this darn truck. It's my first Ford and I liked it so much, that I convinced my wife to get rid of her 1999 Suburban and buy the 2001 Expedition XLT with the 4.6

Does the price of this replacement motor sound right? Whew! big bucks...

Any alternative suggestions would be appreciated.

jrc346 · February 2004

What exaclty caused the failure? I have had nothing but good things to say about my 5.4L, now at 96,500 miles and no problems.

I change the oil at 7,500 miles and I DO have to keep an eye on the oil level. It uses about a quart of oil about every 1,000-1,500 miles. That would probably bother some people out there, but not me. When I think about what my engine does in those 1,500 miles, it kind of makes sense. At those hot temps some of the oil is going to evaporate and get sucked into the intake through the PCV system. Sorry to hear that your Ford loyalty is being tried. Put in the new engine, and just keep an eye on that oil;-)

docknow · February 2004

Put in the new engine. I have 167,000 on my 1997 F-150 ext cab flareside. I use about a quarter of a quart every 4000 miles, the oil is always changed every 4000 miles, the only thing I have done to the vehicle in 167,000 mile is replace the ball joints at 125,000 miles because the factory saves .20 cent per vehicle by not putting grease fittings on at the factory. This is the best truck I have ever had, I plan on driving it until it has 250,000 miles.

Good luck with your truck.

northstart · February 2004

Hi guys. Im going to start looking for an oldish F150 later this year to use as a promotional vehicle for my business here in England. I?ve looked a number of trucks of all makes but I like the look of the mid to late 80s F150

Therefore I was wondering if anyone had any experience (or problems) with these. I know all of the usual things to look for and a truck of this age isnt going to be perfect but did they have any major vices that I should watch out for?

The model I will be looking for is a long bed regular cab V8 auto, probably a 4x4 but I would rule out a 4x2

9750 · February 2004

I bought an '04 Lariat in January. Now I've got 3600 miles on it. Yesterday the check engine light came on and the information center read something to the effect that the engine was operating in SAFE mode.{I can't remember the exact wording} I took it to the dealer and they couldn't find anything wrong, so they reset the codes in the computer. The dealer checked with Ford and found that there have been problems of this sort, but they should have new software to download in about a month???
I back out of the garage this morning, and the same thing happens with the check engine light and SAFE mode. Is anyone else having problems like this?

jrc346 · February 2004

I have never thought to post any question about my 79-F-150 in here, but why not? Anyway, my 1979 F-150 is a regular cab, long bed 2x4 with a 302 (5.0L) V8 with the C4 three speed auto tranny. It was restored and repainted a dark green (couldn't stand the poop brown color), however it is a continuous project that I work on in my spare time. The frame and engine bay are still in need of refurbishment and cleaning. The bed will have to be replaced in the future as well, but for now it looks nice! Anyway, enough of that crapola, now to the important part.

I bought the truck at 90,000 miles 5 years ago (It has 128,000 currently) and shortly after I started getting a rattling/clanking noise from my engine when traveling at highway speeds (60MPH +). It only does it when in drive (wont make noise when held at the same RPM as on highway while in park) and is inconsistent, meaning that it comes and goes. It also only happens when I am just cruising, so if I press on the gas harder or take my foot off the gas, it stops. This seems to have been a problem since I had a new carburetor put on. I have also done a top engine clean, had my timing adjusted, tried different octanes of gas, and while some things seem to help it, it never goes away completely. I don't know where to go next. Do I look at the distributor for problems with the vacuum advance or do I turn to the electronic spark controller, or is the carburetor the cause of my problems? How about the EGR valve or a vacuum leak? While the noise hasn't really gotten worse in the last 30,000 or so miles that it has been doing this, I am worried about the damage it may be causing to the engine. Plus no one can tell me what the noise is. The truck runs beautifully, and gets about 14 MPH average, which is great, but I don't want to be stranded someplace or have to put in a new engine right now. So, if there are any ideas out there I would be greatly appreciated to hear them:)

akjbmw · February 2004

I put a 351W in a '62 Comet once upon a time. When I rebuilt the engine before stuffing it in there, I didn't get the single bolt that holds the eccentric (drives the fuel pump) attached to the front of the cam tight enough. It started flopping against the inside of the cam cover with a REALLY un-nice clanking sound. Major sphincter action.
This may not be what you have, but if the timing chain tensioner is getting worn, it might be touching the cover and providing you with the unfriendly sounding clanks.
Might be worth a check see, especially if your water pump is getting up there in age (while you're at it).
Good luck and happy trails.

wijoco · February 2004

Can you describe the sound? Is it a spark knock or something else? I've had a few 70's F100s with the 302s and Iv'e piddled with them quite a bit.

jrc346 · February 2004

First off, thank you for your willingness to help me out with this one. Who knows, maybe we are on to something?

Now, the only battle is trying to figure out how to make the noise appear on this page. I think rattling is a pretty good start, but that can mean a lot of things. To me it sounds like valvetrain noise. Like a rocker arm and pushrod are just flapping all over the place. However, this only happens when I am cuising with a steady foot on the accelerator going 60 MPH +. Another way I can think of this noise is when you take two spoons and hold them together back to back and shake them (haha not sure if this is how that works with the spoons, but I have seen this done with certain music (bluegrass?)) So, take that noise and do it with 3 or 4 sets of spoons rapidly, it would sound like a rattling or clacking. It can be clearly heard inside the cab. Not sure if this is actual detonation or not. I find it strange that it goes away the more I press on the gas. I did forget to mention that I did the top engine clean because the noise became much louder. I was really nervous that something was about to go, and thought that it might be possible that I had carbon buildup in the top end of the engine that was causing the ruckus. 50% of the noise was gone, but quickly came back (100 miles) to the way it was before it became louder. I am about to pour some more money into the engine. I need a new radiator and I have a coolant leak somewhere (not the water pump). So one of these days I will have to get the hood open and spend a day with it. Again, thank you for your help.
JRC
p.s Would the noise coming from the cam cover happen at any other time (idle, acceleration, etc) or just at the times I am describing? I have been told before that this could be a place to look for an issue. Also, would the performance of the fuel pump be effected if this was happening?

akjbmw · February 2004

JRC. How're the bushings in the distributor?

jrc346 · February 2004

Huh, didn't know there were any. Where do I find these bushings, and what will they look like if they are bad?

wijoco · February 2004

The way you describe it would be consistent with pinging, you only hear it under certain throttle positions. I don't know that's what it is, but you can check EGR operation under part throttle to see if it's all working. You may have to pull the intake off and remove the EGR assembly and clean it if it's carboned up. There are a lot of small EGR passages in that intake that get plugged up over the years.
You mentioned that the noise started after putting a new carb on it, I wonder if the new one is a perfect match? If not you may have a lean condition in certain ranges. Do you still have the old one by any chance? This is hindsight, but I always prefer to rebuild an old carburetor rathe rthan replace it for fear that the parts store will sell me the wrong one, or one that was rebuilt with the wrong metering valves etc.
It could be a million things, hopefully it's not engine trouble.

jrc346 · February 2004

No I don't have my old carb, I gave it back to get some cash for the core. Guess that wasn't a good idea, but I have never rebuilt a carb before, plus I know zilch about how to adjust them. I know that it is leaned off ever so slightly for gas mileage reasons, so maybe that could be what is causing the problem? Again, I have no clue how to make the mixture slightly more rich. I do have a Haynes manual, and I have seen adjustments in there, but I don't want to mess something up haha. I am thinking seriously about looking at the EGR. I haven't ever cleaned it, and since the top engine clean made a difference for a short while, it kinda makes sense. What do you think? Thanks for the imput, I may be able to work on it this weekend. Take care.
JRC

wijoco · February 2004

One other thought I had: Check the tensioner bolt on the distributor hold down. I had to put a new distributor on my 79 302 and after about a week the thing was pinging like crazy, getting worse each day. Turned out I hadn't torqued the hold-down bolt tight enough and the distributor was slipping and advancing itself as I drove it. Whoops!

akjbmw · February 2004

The rotor is attached to a shaft that turns within the distributor housing. Most of them have a greased bearing surface (called a bushing) that will eventually wear to the point of allowing the shaft to wobble around. This changes the timing more and more as it wears. Especially a problem when vacuum advance was implemented.

Thanks guys, the rear doors are fully shut and it only does it when there is a crosswind at highway speeds. Bummer that there aren't any usable visors from Ford. Is every one else driving blind too, or are there some aftermarket ones out there anyone has found. I can't imagine driving the truck for years like this. I'm 5'8", shorter drivers must be going through worse than me.

akjbmw · February 2004

I wear a hat. Adjusting the tilt of the hat or my head sets the visor position. It's really a carry over from being in the military, but it still works with a civilian hat. ;-)

todd1965 · March 2004

I just upgraded my rims and tires from 255/70R/16 to 285/60R/18, had my speedometer adjusted to post the correct speed. Is there anything else I need to do to ensure that I don't do any harm to Ford F-15 SC.

monty2480 · March 2004

I have a 1983 Ford F150 2x4 pickup truck that needs some TLC. I have been experience a problem and hoping someone out there can assist me with their knowledge. On a nice sunny day the truck runs great, but on a rainy, or snowy day the truck does not like to run. When it rains the only way the truck keeps running is, if I have my foot on the gas. As soon as I take it off the pedal the engine starts to shake and the battery gauge moves back and forth, as if the truck was going to shut off, but then soon does. Many people have told me that it could be the spark plugs wires, spark plugs, distrubter cap, and the rotator. I have put all of this in and still experience the same problem. I am out of ideas. Please help.

bolivar · March 2004

I too would have told you to replace the rotor, dist cap, wires, and sparkplugs. Overall, these are not that expensive and are the problem with hard starting and missing on older vehicles.

I hope you got the pre-formed wires with plugs already on both ends. I've never have very good luck in cutting wires and getting what I thought was good connections out of those 'make your own' wire sets. If you've done this, I recommend you get another set of pre-formed ones.

In general, you must have a short somewhere in the ignition or charging wiring. I can't give you any more advise about where to look. Unless there is some kind of open connection in the alternator that moisture is getting to, it should be in a wire.

Something you might try - get a spray bottle that will put out a strong mist. Start that sucker up in a dark place and start misting around in various places. You might be able to see a electric arc, or you might be able to narrow the search down when the spray hits a certain area under the hood. Keep away from the fan in the dark!!!!

Another thought. On Fords of mid/late 70's, there were a lot of problems with an electronic ignition control box. These problems were mostly caused by heat. My wife had a 1978 Tbird that would not start hot. I put a bag of ice on this box (on driver side fender well), and after a few minutes it fired right up! And the after market parts places had the 'box', and said they sold a lot of them.
Happy hunting!

wpalkowski · March 2004

Todd,
  By changing the tires/wheels you're probably not hurting anything. The new rubber is about 1.5 inches bigger in diameter - so as long as it doesn't rub on the insides of the front wheel wells when you're making tight turns, everything should be fine. You had the speedometer ratio changed, so everything should be reading accurately.
   Only shortcoming with the larger diameter tires is that you lowered your final drive ratio a bit. Not sure what's in your F150, but if it started out with say 3.23:1 rear axle, the result with the bigger tires might now correspond to like a 3.08:1 ratio. Not a real big drop, but you might notice that the truck is a little bit slower off the line, and has a somewhat harder time getting up to speed if towing a load. However, there's a small benefit, at highway speed you may get an extra mpg or two.
   Folks who go to the real big tires alot of times end up changing out the rear-end gears to a higher ratio to restore the power that they lost.

wijoco · March 2004

But after the intitial 15 minute warm-up period, it runs OK, I bet?

vidtech · March 2004

you did not mention the type of fuel system you have.if it has a carb.i would check for possible carb or throttle body icing.i had similiar problem with an old ford.check to make sure the heat tube which provides heated intake air is working properly.

bolivar · March 2004

Hey, I agree.

I now remember a mistake I made years ago.

I had 72 Corvette with true dual exhausts. After replacing the right muffler two times, and the left one was still good, I came up with the great idea of wiring the 'flapper' open on the right exhaust manifold. This would, according to my brillant mind, allow the right exhaust system, including the muffler, to warm up more, especially on those short trips which were obviously leaving lots of water in the right muffler and rotting it out in a short time. (Remember, this was the days of leaded gas, and muffler replacement was a normal maintenance item. Unleaded gas saves us from this problem.)

Of course, this weighted flapper and spring valve was dirverting hot exhaust gas across the base of that Quadjet carb.

Wiring it open caused the car to be deadly. It would start ok when cold. But from an idle, pressing on the gas would cause it to drop dead! After almost being rear-ended a few times at stoplights when the light turned green and I have a stalled out Corvette, I decided my life and my fiberglass bodywork was worth more than the cost of a muffler. Unwiring it solved all the problems I had caused.

Check this old Ford to see if the carb is getting heat!

I have an 02 F350 7.3 power stroke diesel which has a slight vibration. It occurs just before the transmission shifts into high gear at around 40-50 miles per hour. If you are really pushing it you don't feel the vibration;if you are taking it easy you feel a slight vibration just before the shift.
