I have a 2003 ford explorer sohc 4.0l , that starts only with the gas peddle pushed to the floor and will only run for a couple of seconds at a time. Just replaced all the timing chains and tensioners. It has 145 lbs compression, and 60 psi fuel pressure. No codes on the computer.
View 8 RepliesI have a '92 Ranger with a 2.3 liter engine. She starts and runs a couple of seconds and shuts down. I'm thinking maybe a fuel pump is not putting out thepressure needed. Gotta go to work tomorrow and gotta get the truck running today.
View 2 RepliesWe've had two problems within the last week with our 2002 Sport Trac (4.0l SOHC engine w/167,xxx miles). They may be unrelated, but I suspect there's good change they are. Both incidents happened while my 16 yo daughter was driving, so there's only very limited info on what happens. Both times, when I get there, it starts and runs fine. There is no CEL.
The first time it apparently stalled as she neared her destination after driving only about 2-3 miles at 35 mph or less after a cold start. She was slowing to pull into a parking lot and reported the dash lit up with warning lights, no power steering assist and no power brakes and no power from the engine. When I arrived it started and ran normally. She had fulled up the day before after two days of heavy rain, so I suspected water in the gas. I drove it more than 200 miles within the next 24 hours under a variety of conditions and filled up at a different station. I experienced no problem what-so-ever, and didn't bother adding any dry gas.
Then 5 days later (still on my fill-up) when she tried starting it after sitting all day, she reported the engine started but ran rough before stalling and never idled normally.
Doesn't the fact there's no CEL eliminate a lot of the upstream part of the control system......like sensors and actuators? This leaves things like the downstream parts of the fuel and ignition systems. I.e. from the fuel tank / pump to the injectors and the downstream parts of the ignition system.
What are the possible culprits? Fuel pump, fuel pressure regulator, injectors, ignition module, spark plugs, and....... what else? (I'm not that familiar with what these engines have) And of the possibilities, what are the most likely causes.
I've had a 1999 explorer for a few months. The transmission has always taken a couple of seconds to "catch" in drive and was then fine. Today, I had to tow another car a short distance and now going into drive directly is useless.
I must shift into 2nd and then back into drive. Then, for the most part, the car drives fine unless I have to put it in Park or in Reverse. Then I must repeat the procedure.
The fluid is fresh and the dipstick shows a slight overfill. Is there anything I can do about this or is this the death of the transmission. If I can run it another couple of years, I'd be satisfied.
I've got 200k on my Lariat. Engine was replaced 60k ago. It's in outstanding shape and is driven a lot. Suddenly this morning I start as usual and it runs about 5 seconds then stalls out. Every start, same thing. So it seems I am getting fuel pressure to start but it doesn't last.
I did replace the Fuel Pump Module within the past two years, due to corrosion of the FPM housing. At that time the truck would no start at all. Could it have gone bad already? I'm thinking this must be an electronics failure. It was perfect all day yesterday. 2004 Lariat 5.4...
The truck started acting up while driving. It would shut off (no miss or anything), but would start again. Now it is sitting in the driveway and wont run more than 3 seconds. The fuel pump has been changed and did not work. The fuel pump relay is new and did not work. I read that the fuel pump goes to another circuit after start up. Could it be running to start and then shutting off? Inertia switch is not tripped. Where to look next. 1992 Ranger 6 cylinder ....
View 10 RepliesI have a PS 6.0 in my '04F350 that starts very reliably but stalls within 1-2 seconds. Restarts after cranking for 5-30 seconds. This only occurs if the truck sits for more than 6 hours. The longer the truck sits, the longer it has to crank to restart. Also if the tank is full and the truck is parked pointing down hill this does not occur, if it is parked pointing up hill it occurs even with a full tank. Shows no codes. I've had several mechanics look at it and no one has been able to explain or propose a solution expect for wholesale replacement of parts. The symptoms indicate to me that air is getting into the fuel system but I'm not sure where to look.
View 10 RepliesCar has 6600 miles on it and is back in the shop for 2nd time to determine what is wrong. Basically, the car starts and then stalls out after a few seconds. It will not start again (at least with me). Course, the dealer can get it started after the tow to them.It began in April after an oil change at the dealer. A week after the change, it started up and then a message SHUT DOWN appeared on the dash.
The car stalled and would not restart. When it was towed to the dealer, it had no oil. Per the dealer, there was no leak and it was assumed the tech forgot to put oil in it, They indicated it was not a problem since there was some oil remaining but the car would still not start. They kept it a few days and replaced the relay for the fuel modulator, electronic fuel pump, fuel unit, fuel pump control unit, e-control unit and of course the battery. Note: this was a cold start.
About a month later, I had driven the car for about 30 minutes, left it for an hour and came back to the car.....it stalled again right after start up and would not restart. After being on hold with roadside assistance for awhile, I tried it again and it started without issue. .
A week later (today), used it for a half hour, came back to use it 3 hours later and same story. Started, then stalled, no restart. Towed it to the dealer and the tech got it started but no codes telling him what is wrong.
00 XLT 4.6 4x4 135k miles - New problem, on accelerating, truck hesitates for a couple of seconds before rpm's pick up. There is no stumble or bogging. It feels like I'm not giving it any throttle at all. And then it kicks in and takes off. It does this from a stop at idle, or at a steady cruise. Its an intermittent problem. No CEL. Air filter and fuel filter are about 3 months old. Haven't done any work to it since. Also, when there is less than a 1/4 tank of fuel, truck sometimes stumbles slightly off idle. Fuel pump starting to go?
View 6 RepliesI am working on my father's boss' 2004 Phaeton V8. The car usually sits on the weekends. What it is doing is, it will start and run smooth, but after 15 seconds, on the dot, it stalls and dies. It sounds like it is starving for fuel.
What I have done so far:
LH intake actuator arm found broken, replaced both with "Gruvenparts"
Checked all fuses and relays
LH fuel pump reads 14 volts until the relay kicks it off
Tested fuel pressure-good
Batteries fully charged
LH fuel pump reads 0.7 ohms w/key off
RH fuel pump reads 6.0 M-ohms when first connected and gradually climbs to 31.5 M-ohms
(I assumed this meant RH pump was bad and so I pulled it out and bench-tested. Ran perfect and tested at 0.7 ohms out of the car)
Re-assembled everything to pull the car out of the shop, and wouldn't you know it started and ran like normal.
Road-tested for 2 hours the next day without any problems.
So, I call the customer to pick it up and he says he will be there 2 days later.
2010 Cobalt, LS 2.2 Ecotec, with 13.7k miles. Oil level normal and battery voltage = 12.5V.
I've bought the car new in Feb. 2001. Car started and ran normally for the work commute on Friday, 9/2. Today the Cobalt starts normally, runs for 2-3 seconds, and then stalls. The accelerator has no effect. It's already been towed to the dealer..
Tried starting the truck, fired ran good for a couple seconds, then ran extremely rough for a couple seconds then died.
I did some research and changed the ICP because there was oil in the connector so even if it wasnt causing my issue i wanted to replace it.
Now I have the same issue but it will actually run a little longer and not stall. I thought it was fixed so i took it for a drive, after about 3 miles it bogged down and i was able to make it home with half throttle going about 30mph. Sounds almost like its running on half the cylinders. i unplugged the ICP and it continued to run that way.
I had done the 50cent mod a few years back with the peices from ford but i know the harnesses themselves can wear through so i checked the resistance between the center pin and the two pins to the right and left for both the injector harness and they had about 3ohms.
I am leaning towards an IPR but from the reading i have done it seams like most trucks will not restart after they die. I have AE so i am going to hook it up later today, just wanted some reccomendations on what to look at.
I also remember when i shut it off the unplug the ICP to see if it would clear up the needles on the gauges did a full sweep as if i disconnected the battery which i though was weird.
My car runs great except occasionally after I drive awhile, park and than restart to continue, it starts right up but stalls out 20-30 seconds later. I turns over but will not run. I have to let it sit for 30-45 minutes and than it starts up like a champ. I suspect fuel pump but would like an expert opinion. Garage says they can find nothing wrong and to bring it in when it happens... how do I do that.
View 1 RepliesOne of my friends recently asked me to change the timing belt on his 2004 Passat 1.8T. I put on everything as instructed by the manual that the parts department gave me. However, when I start the engine, it runs perfectly for about three seconds, then starts rattling, and stalls out. I took the belt off and put it back on three times and yet, it still continues. This rattling seems to be coming somewhere from within the exhaust system near the engine and sounds like a back-fire. The check engine light also appears when this begins happening. I replaced everything, water pump, pully, tensioner, and etc. Note, I am a professional mechanic and have worked on several Volkswagen cars, including my own, but I never encountered a problem like this one.
View 7 RepliesI have Warn hubs that I have to lock in. All works good. A/C goes to defrost at first when cranking but then runs fine after a couple seconds. So, I was thinking that maybe my pump is running all the time. Who knows. I'm sure all my vacuum lines are dry rotted. What exactly is the need for it exactly and what's the best way to cap? Hoping to do it at the unit itself if possible.
View 6 RepliesMy 2001 Prius (230,000 miles) is unusable. I can clear the codes. The engine will start up fine. After a few seconds it starts bucking and jerking as if the engine is trying to engage something that won't turn and finally stalls. It is similar to a manual transmission car's action if you fail to push the clutch in when you stop the car. What the engine is trying to engage? I don't have any scanner to read the codes.

View 8 RepliesI had the engine out of my truck (7.3 with e4od) to do manifolds. Anyway, I got it back in and started it up. Since there was air in th fuel lines it had to crank a couple seconds but started up. I looked and now fluid coming out, then it sat for a few minutes running and I took it for a drive. While sitting in the driveway it wa smoking a bit. But I thought it's from the oil I got in the exhaust while drilling two of the manifold bolts and soaking the bolts with ATF/acetone. After about half a mile I thought that maybe it's more oil then that would cause... So I went back. I looked and the inside of the exhaust is covered with oil, and the rear of the engine is also.
When it was out I capped all of the open ports so I could pressure wash the grease off. Also, I flipped the CCV so I could do the delete. During instal, I missed the cap on the CCV and it was not able to breath. I think that maybe it built up pressure and blew the valve cover gasket? It looks like it's coming from the right cover on the backside; I had not taken this cover off while the engine was out. How much pressure does it build? Is it possible that it could have blown the gasket out? I have done the oil cap trick to test blowby and it always passed the test. What it could be? For the leak on the engine and why it's in the exhaust?
So I had a reman 7.3 and 4r100 dropped in my 03 excursion.. since then the engine fires up every single time.. ONLY when the truck sits for 2 days i have this issue where the truck fires right up, runs for 4 or 5 seconds then stalls out.. It starts back up on first try and idles rough 10 seconds then it runs great.. If it only sits 1 day i dont have the issue if it sits 1.5 days it will try to stall out and catches itself from stall out and doesn't stall about 3/4 of the time. The mechanic who is a reputable diesel mechanic cant figure it out.. they called swamps and they also were unsure.
View 9 RepliesI recently sold me 91 F-250 and got into a 98 F-150. It's a SuperCab 6.5' bed, 4x4 off-road, 3.55 gears, 5.4 v8 auto. I love the truck, but I am having an issue with a noise at startup.
Every time I start the truck it fires right up but it makes a grinding noise AFTER it starts for about 3-5 seconds. I thought the starter wasn't disengaging in time so I replaced it. The starter I took off was fairly new. It's teeth had just a little wear and the flywheel had no visible wear. I put in the new starter and there was no change at all.
I also changed the oil and filter using Motorcraft 5w-30 oil and a Motorcraft filter. I also started it without the serpentine belt to rule out a pulley bearing. What the noise could be? The truck runs absolutely excellent, by the way.
If I don't keep in the throttle immediately after start up it will stall a lot of the time. It doesn't do this every time or if it sits for a while but if I drive it and then stop off at a store or something and then go to start it back up it gives me this problem. I notice it idles about 3-4k RPM's when I stop at a light or something too.
