    1 - 8 lug x 6.5 bolt circle. Be sure to check the offset though.

    2 - I keep mine stock. 325/610 is plenty for me

    3 - Depends on how much you want to spend. you can have a cat-back dual, or someone will certainly make a dural from the exhaust side of the turbo, but to stay legal, you'd need dual cats

    4 - Only thing I've done to the intake is swap the paper filter for the Fram AirHog reusable

    5 - As for that rough running on cold-day starts, that's also normal. Diesels of course run on high compression and heat, and it takes a short while to get the cylinder temps to where combustion is complete

    trouble code came up as fuel control module voltage low on my diablo sport programmer. truck died on highway. finally got it started and it ran for about 5 miles then died again.
    it wouldnt start again after that. same code came up again after clearing it out. is this anything to do with fuel sending unit in the tank or module on the back side of the fuel canister? please help

    I have a Dodge Ram 06 with diesel engine and has 6000 mile on it. I see a lots of black smoke out whenever I step on the gas, and yes soot too. On 5700 mile, I changed the engine oil. Before I changed the oil, the oil was black. Now just 300 miles on it, the oil is back to black again.
    Any idea anyone?

    The black oil is "normal" (it won't stay as clean as an older Cummins - my 1996 would stay clear for thousands of miles, my 2005's oil is dark in 24 hours after an oil change), the black smoke is not normal. Black smoke is unburned fuel - you need to have that checked.

    I am going to purchase my first diesel truck this month. I have read a great deal about Ford, Chrysler and Chevy's diesels. I have narrowed it down to the 2007 chevy with the Duramax or the new 2007 6.7 liter Cummins(supposedly out this March). My question is regarding fuel mileage. It appears from this post and others that the cummins has the reputation of providing significantly better mileage. Would you agree with this? It is especially important for me because in addition to towing, I will be putting several thousand miles/yr of unloaded highway driving. Any opinions on unloaded highway fuel mileage between the Duramax and Cummins would be greatly appreciated as well as general opinions regarding durability and features preferences between these two.

    Thank you.

    I changed the oil on my new 06 with only 400 miles on it and it was black, I also changed the oil on my 93 with 3500 miles and it appeared to to be much cleaner than the previous, made me wonder a bit as well.
  • this is caused by the intake heater cycling on and off until the truck warms up.

    Hello Everyone. I am new to this forum.
    I have a 2006 3500 Diesel. All of a sudden, will not crank. Almost like something in the electronics has the ignition blocked or neutral safety switch or something. Everything works and batteries are up. Turn the key, no click, no crank or anything. Anyone ever have this problem or any suggestions?
    Thanks in advance.

    I have a 1998 dodge cummings diesel that when going into drive or overdrive or up hill and appling power it shutters just for a second but mash throttle on down it smooths out.Any suggestions? Also when Engine/trans is cold and you pull it into gear it will sometimes not move but rev engine up and it slams into gear and will pull and it will do this if you stop,change from forward to reverse and visa versa for the 1st 3 to 5 min. of operation depending on the outside temp. Warmer weather it does better with hessitation and shuttering.I have changed fluid and filter many,many times over 5000 mile stretch .I have tried recommended ATF and all the way to Allison Trans Synthetic at $48 a gallon Which does help it some.($144+tax in just fluid per change):cry: Please Help

    Hello All. I am new to this forum, and to diesel engines. I recently purchased a 2006, 2500 Dodge with the Cummins engine. With low-sulphur fuel now being supplied, are any additives required to run the fuel in 2006 engine?

    Thanks in advance.
  • KCRamKCRam Mt. Arlington NJPosts: 3,516
    Absolutely none. My 05 Cummins runs just fine on it.

    The 5.9 cummins has a 100 k factory warranty. Any work they did to your Ram that did not repair the problem you should not pay. I would go to another authorized repair center. Dont drive the vehicle, your problem may suddenly go catasrtophic. I.E. dropping a valve. Hope this helps
  • Hey Ya'll. I just found this forum and I'm wanting to meet up with some diesl folks in my area. I'm from Hernando, MS. I have a 2004 3500 quad 4x4 Dodge with the 5.9. I added a bullydog programmer, banks monster exaust, and a Canadian transmission a friend got me. I run her some at Memphis Mptorsports Park. Averahe in low 15's. No feet on it yet. I also pull a travel trailer with it. If there is a local club or group I'd like to hear about it. Thanks, and remember if it ain;t blowin black its just another ride

    Hello Freebird, You couldnt have chosen a better ride. My Ram D350 Cummins has 328,000 miles on it. I have 370 marine injectors, BorgWarner Turbo, 4"exhaust and a #8 Fuel plate. Their fun to drive especially when you bomb the motor. It's such a durable engine their still reliable when you hop em up. Im getting about 350 horse out of mine. Love to smoke those gas engine trucks, literally leaven em in a black cloud; feels great especially after they have been tailgating.
  • Hey Carnut17, went tothe track thurs night and ran a 14.623, my fastest so far by 2 tenths.Havn't been there in awhile. Huge crowd so I was inly able to make 1 run, but it was a good one. My light was bad .101, but I smoked a Mustang. Thanks for the reply. Maybe we'll hook up on the road someday.
  • Don't have the money for 2 sets so here goes. I like to run at our local track, but I also pull a 29 ft travel trailer. Anybody got a suggestion for a compromise tire for stock rims on a 3500.

    I have a 96 Ram 2500 auto and when driving normally but most of time I will have a trailer behind, the rpm go up and down often. I don't know if something is wrong or not. If anyone has a suggestion or fix for this problem, please let me know, this is driving me crazy. Email [email protected] asap.
    Thanks

    I have 95 3500 deisel that does same thing. torgue converter is disconnecting and connecting randomly but I don't know why. I have rebuilt transmission and replaced torque 2 times and it still does it. Have been told it isn't the transmission but something electrical but no one seems to be able to find exactly what.Sorry I don't have a positive answer to your question but maybe someone will respond that does.

    Jim,

    On your vintage RAM the electrical connectors at the transmission had a propensity to corrode if the connector housing wasn't sealing correctly. That's a very common problem and could cause you to have intermittent Torque Converter Clutch (TCC) engagement.

    Your symptom is also a sign that the correct ATF wasn't used or has been contaminated. Chrysler/Dodge automatics are extremely sensitive to the ATF type and quality. Dexron-Mercon should never be used, not even a drop! You should have at least ATF+3, and ATF+4 would even be better.

    Another problem I see occasionally is the Transmission Control Module (TCM) looses something in the memory and has to be re-flashed. In fact, I have a good friend that just had this occurrence on a 2000 RAM.

    Best of luck,
    Dusty

    When it starts to surge, step down lightly on the brake pedal. Only enough to turn the brake light on, but not enough to engage the brakes.
    Does the surging stop? If so, then you have a TCC solenoid problem and there was a Programming reflash for that problem. Which may or many not solve the problem.

    If the surge still continues, then you have a deeper problem than the TCC solenoid or possibly a Vehicle speed sensor problem.
    Have you had the vehicle scanned to see if there were any trouble codes?

    To MANLAWN and JAMES59 replace your throttle position sensor and your troubles will disappear. The part is about $200.00 but i am 99% sure this is the problem. The TPS is located on the left side of the engine in front of the injection pump. It is a black piece of plastic w/ three wires going into it located on a pivot point at the end of the throttle cable. Fairly easy to replace, Thanks Carnut17

    Maybe it's some sort of reminder to "check engine". I mean as far as the fluids are concerned.
  • james59james59 Posts: 4
    The throttle position sensor was the culprit. Fortunately I only had to clean the connection with carb cleaner to remove grit and oil and it hasn't missed a lick for past 1200 miles. Thanks for the info.
  • New member - Yuma, Arizona area.

    I have owned a '96 Dodge 2500 Deisel 2WD for several years; aside from seeming to be a little hard on brakes, its been fairly trouble-free. I've been changing the oil every 5,000 miles or so and have been replacing the fuel filter every 3rd oil change. In December '06 I suddenly started having problems starting. Engine would crank over OK, but it acted like it wasn't getting fuel; I'd have to pop the hood and pump the primer several times; then it would start. This was occuring 3-4 times a week. I took it in to a diesel shop; picked it up later that day after paying $732 for Fuel Shut-off Solenoid Kit(with labor). Mechanic showed me my old one and I saw the rubber boot was fairly well worn and the internal shaft was broken. Around the first part of March I started having the same problem. Doesn't seem to make a difference whether engine is hot or cold. I haven't experienced any problems with acceleration or performance even while pulling a load.

    I don't have a workshop or enclosed garage for a comfortable work area and don't have much more than the basic tools. Aside from replacing a starter and doing the brake pads and shoes, I'm not equiped to take on any real challenging repairs. I have the HAYNES manual to refer to and have read through the Troubleshooting section. I'm the typical 60 yr old home week-end mechanic, but only when I have to be.

    I've never kept track of mileage, but haven't noticed any drastic changes; There have been no indications of any fuel leaks. One difficulty I did have while replacing the fuel filter: I replaced the little O-ring on the water-in-fuel sensor, but really became frustrated trying to get the old thick, flat O-ring seal on the filter housing to come off. So it wasn't replaced.

    My hope is that some member has maybe experienced this same problem and has a simple and inexpensive solution for me; or some ideas on what I should be checking for. thanks, Michael Fisher
  • I guess I should have spent time exploring this site before posting my message; I've read through several posts and areas and see I'm not alone with this 'starting' problem. Sounds like I need to have my batteries checked and look into my fuel pump maybe. Thanks, Michael

    Normal.

    It is the heaters for the intake cycling. The electrical system can keep up with the voltage draw.

    My 07 does this from new but I have two batteries and bigger alternator

    I just got rid of my 300C and am now into an 07 Ram 2500 Laramie with all options. I picked it up as a demo and it had 19,800 Kms. on it. I made sure that a full service was done on it, but I do have a question. I checked the oil when I got home and it is still very black. I do know that there is a new oil filter. Is this normal? I have never had a diesel before but so far after a week, I love it and fuel costs are way lower than gas, and I just heard that gas prices have jumped again for the second time this week in my area of Canada.

    The only sad thing is that I put a crease in my right door yesterday while backing out of my garage(I must learn to drive)so I went to my local dent guy who I have used in the past and he says that he can remove the dent but the crease will be visible. I hate black vehicles but the price was right!!!!!

    I have a 2000 2500 dodge diesel. the throttle will loose control frequintly. You start it up idle down the drive to the hiway when you put the trottle down it may or may not accelerate. Also when traveling at any given speed and you add more throttle it wont accelerate iot will maintain the same speed. This happens at any time. We replaced the primary fuel pump because the machanic thought it was the problem. Got any ideas?
