Ford Explorer Starting and Stalling Problems



  • Could be Mas Air Flow Sensor ! Also, the O2 Sensor will cause this same problem you are having !

    Dealership has placed a `little black box' in the truck. I'm supposed to press a button when it stalls ( while throwing it into neutral to restart it and avoid being in a collision!) Fortunately the extended warranty ended today and they are keeping the ticket open. Unfortunately they are no closer to figuring this out and I'm driving in a very scary vehicle. It just reached 50,000 miles. You would think that a $30,000+ vehicle would last longer than 5 years!
  • i have tried everything yiu can think of it set no code the check eng lite does not come on it just spins over and over until outside temp gets above 60 degrees and then it fires up and runs like new.
  • i recently got a 98 explorer sport and i ran into a starting problem. the engine would turnover but it would start. starter fluid seemed to fix the problem but when i used it today to get it to start not only wouldn't it start but i got back pressure that caught my air filter on fire. im trying to figure out if there is a problem with the exhaust system or if the engine itself may be the problem any input would be welcome

    I have a 2003 Ford Explorer that will not crank each time. It won't turn but the lights and radio work. Usually this happens after we have driven the truck somewhere and got out only to return to the truck and it won't crank. I took it to a mechanic a couple of months back - had it towed because it wouldn't crank but when they got it, it worked after charging the battery. They couldn't find anything wrong with it but I continue to have the problem at least once a week or so. I purchased a new battery so it's not the battery. Usually it will start again if we wait 10 or 15 minutes.
  • hi we have a 1998 ford exploer it ran fine the other day but we tried starting it today but it wont start, we changed the spark plugs on it recently, we are just wondering what can it be?

    I have given up on my 99 explorer 15 service calls with no perminent fixes. Bought a Chevy Tahoe, Explorer going to scrap for $75.00 a ton. Sad but I will never own another ford in my life.
  • I started to wonder if the after market car starter had anything to do with this. My Windstar also started having electronic issues shortly after I had the car starter installed. The door locks locked and would not unlock unless I used the remote or rolled down my window and punched in the code on the keyless entry. I have gotten rid of my Explorer. I really liked it except for the fact that it was a death trap! Stalling whenever, for no particular reason. It was in the shop a dozen times or more. The little black box the dealership installed never registered it stalling the five times it did BUT it did record the ignition being manually turned off ( I wanted to see if the thing actually did record anything!) If the computers don't recognize there is a problem, it won't register a problem and if there is no recorded problem, FORD will not cover it under warranty. I too will NEVER BUY ANOTHER FORD again!
  • I also own 2003 and found out what the problem was, remove the cover under the passenger side there u will find the fuel pump switch press down on it and ur truck should start.

    Did you try to replace ECC relay?
  • gonfrygonfry Posts: 2
    I'm having the same problem but I'll change the EEC relay. According to message # 81 it works.....I'm keeping very positive with this option.

    My 94 explorer wont start at times and sometimes stalls also emits an odor like the mixture is too rich,and runs rough under exelleration.

    I had this problem with my 2002 Explorer. After driving it awhile, I would shut it off and it wouldn't start. When trying to restart it would turn over but wouldn't start. It also would start after sitting awhile. Took it to Ford and at first they couldn't find the problem. What I realized, it had to be over 90 degrees out. Took it back to ford when it was hot out and they found that the fuel pump didn't have full pressure when it was over 90 degrees. They replaced the pump and haven't had any problems since.

    I'm having the same problem with my 2000 Ford Explorer, except it happened just that day. Took it to the mechanic and they don't know what it is. I see that this happened a while back...any insight you could share would be greatly appreciated.
  • After some trial and error, I began to remove the fuel pressure sensor and discovered one of the lines had a break in it. I believe when it got hot, the gap got larger and the fuel mixture got too rich, as the sensor was calling for more pressure from the pump. Replaced the sensor and the line, Problem solved. I got the car cheap because the previous owner couldn't figure it out. Glad I stumbled on it.
    If nothing else is working, check those lines!

    As of today- the day of the posting. I have the same problem , I bought a brand-new Starter and a new battery(the good one)No luck! just a click each turn of the key :( !! I have straced the wire for any short in them. I'm stuck!! I think the starter gets stuck by the flywheel.. but not sure :mad:

    I have a 1998 mercury mountaineer and about a month ago I went to go somewhere and it would not start. Then later on in the day it started. It never did that again until last week then everyday it seemed to be a hit or miss thing so we had the fuel filter changed and a new battery put in and it ran fine for a few days but then the next day it wouldnt start. Yesterday It wouldnt start and it ran fine the day before then we tried it lastnight ,started right up and we drove it with no problems then this morning wont start...we tried jumping it but it still wouldnt start. Does anyone have any idea what this could be????
  • Check your crank shaft position sensor. If you get under the car and locate the crank shaft you should see a plastic piece with 3 bolts that brushes up against the crankshaft. You will see a plug going into that piece. Give it a jiggle next time it wont start then try to start it again. I had the same problem with my 97 explorer and it always works. However, If you go to the auto stores to get a new one they will give you something that looks nothing like the existing sensor. Still trying to figure that one out.
  • I recently notice that my 02 explorer is hesitating to start. I have change the battery out I even went way over the cc amps I would figured that would resolved the problem due to it had a under rated battery in it but the problem is still there. It sounds like the fuel pump life is near for it but don't want to replace fuel pump if its not that.

    Would appreciated if any one has had this same problem would let me knw wat they did to fix it.
  • Replaced my fuel pump, battery, and several other parts it is not any of them it is still not starting every once in a while. I plan on checking the fuel pumpl lines like that other post said he did. Good luck.
  • I'm thinking it might be the starter relay. I have a 01 Lincoln ls V8 and I also had the same problem with it. It would start fine sum times then it would hesitate to start till it really wouldn't start at all I thought it was maybe my starter so I took that out and took it to get check and it came back ok. So wat I did was I took my car to the Ford dealer since I had warranty on the car and they told me it was the starter relay that was screw up. And it sure was they replaced it and the car starts with no hesitation.

    after replacing starter, ingnition switch and neutral safety switch, battery good
    the truck will not start if I jump the starter with screw driver it starts and stays running, it sounds like the problem is between ignition and starter,
    anybody has any ideas
    thank you
  • RE: Truck was DEAD! After a lengthy going over, my mechanic brother--who was determined it was the fuel pump causing my truck to not start--found that a little bitty part was dirty! He cleaned it up, blew out the dirt, just wiped it off with his hands, you know. It hasn't had a problem like this since! Everybody I talked to, including Ford, said it was the fuel pump; but I had a gut feeling about it, so I didn't give up looking for answers. I can't tell you what it was, and my brother can't recall what it was--2 years ago, you know. He just put his hand on everything, cleaned up every little gadget he touched; that's how he found it, as he was stumped for an answer. I've had one problem that's chronic: it burns up blend (air) door actuators about as fast as I can get one put on it. I searched for a recall, as I noticed in other forums, that many people had the same problem. Now, I'm no mechanic, and my brother won't even touch this one! But I have torn that truck up--I found it--got a little advice from a forum--I'll have it on there tomorrow! The shop wanted it for 2 days, $55/hour!!! (And to think, I've been teaching school...!)
  • I just picked this up yesterday and was under the impression it was only the mass airflow sensor gone bad. The problem I am having it when I start the car, it will right away rev itself to about 3000 rpms and stay there for 5-10 seconds then will calm down. But when I switch to reverse or drive, it wants to die on me, I always have to make sure Im ready to rev the engine up when I switch to it(and when i come to stops as well, I put it in Neutral before I stop to prevent it from dieing). Also it does not want to accelerate fast at all, and if I were to try and "floor" it, it will try to die on me and I have to let off. I have been reading this whole discussion thread and would you think it could be the EEC relay? or would it be my throttle positioning sensor? EGV issues? im at a loss. im not a very knowledgeable person when it come to cars. PLEASE HELP!
  • I am experiencing the same thing! --one foot on the gas, one on the brake.... But I still don't have heat...first things first, you know! If you figure this out, speak up, as I have a feeling that's the next thing I have to fix. Thanks, and best wishes for continued success with your Explorer--now I know why they named it that--I've never EXPLORED a vehicle as much as I have this one!
  • I recently had the AC compressor replaced, along with a new serpentine belt and they replaced the fuel filter. Now my Explorer only starts sometimes...cranks fine...but takes like ten tries before it catches and starts. Could this have something to do with replacing the fuel filter? Doesn't show up any codes at all when tested but of course it starts at the mechanics shop. It's not due for spark plug replacement for another 5 thous only has 55K on it.
  • After reading other people's suggestions I located the fuel pump relay in the engine compartment and gave it a jiggle, took it out and back in again and now it started today.....fingers crossed , maybe that was it, sure don't want to take it back to the shop where, of course, it always starts up and they can't find anything wrong with it.
  • Go through and clean everything under the hood you can put your hand on; there is a small sensor setting in there that can get dirty/clog up that can give you grief like that. I found it BEFORE I put in a new fuel pump, as EVERYBODY said I should...even the dealer! It was a dirty sensor. I HOPE that's your problem, instead of a fuel pump! I would certainly consider a new fuel filter, though. My brother's friend wasn't so fortunate; replaced the fuel pump and it wouldn't even start--dirty sensor. (I cannot remember the name of one sensor in particular, I just know he cleaned everything he could touch.) I speak from experience only, Lord knows I'm not an expert! LOL
