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..
One 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'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...
My 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 7 RepliesMy 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 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 am having an issue with my 2006 Chevy Cobalt. I recently had a new fuel pump put in. Within a week the car would not start. The very next day the car started fine and ran well. The next day it would not start again. The next day, started and ran fine. Then this morning it would not start again. I don't think it can be a faulty fuel pump. What might be the problem?
View 5 RepliesI have a 2006 Chevy cobalt and am currently stranded with my husband. Last night as we were about to head home from visiting family 3hrs away, we got off at an exit and as we were stopping about to go again because the light turned green, the car stalled. We had to start it a bunch of times just to get it to the nearest gas station about an eighth of a mile down the road. The message on the dashboard said "engine power reduced". We looked up that message online and a few posts said to disconnect the battery. We did that a few times but when we went to go, it kept doing what it did before, stalling. We were almost to the road and decided we weren't going to make it so we put it in reverse and it drove just fine back to a parking spot. Why it would stall idling and in drive but not in reverse? We are baffled and currently waiting on a tow.
View 3 RepliesMy truck started fine my truck was running good. One morning while working from a hotel I went to start it in the morning and it started and stalled more than a few times but eventually ran fine later it did the same thing. The next morning it would not crank at all. I deduced it was the ficm and ordered a replacement the dash was acting funny and tach dropped before it died. I ran the. Test on the dash it swooped the gauges acted fine. I checked and wiggled sensors wires. I also checked were a splice at the crank sensor was it looked good then I bought a meter and the ficm seemed to have the correct volts it was a upgrade. Had 57volts at 1 screw koeo and while cranking.
PCM and replacing the crank and cam sensors. I don't really think it is the harness it will now crank and shut off crank and shut off like it did at first. He said it's stalling because it looses ficm sink. I haven't put new ficm on it ...the harness was allot better than the first. Could the crank sensor splice be wrong it is done its soldered together and heat shrink ... is it the ficm or the dash. I'm out of my comfort level I was also reading it only needs ficm sink to start. Not run. In addition #2 injector is throwing a code. I asked him if he thought the fuel was getting pressurized and his reply was the fuel has nothing to do with ficm sink. Also, I swapped relay out with my other 6.0. And its running fine This is everything I got ....
I'm driving a 95 buick lesabre, good condition, clean, 130k miles on it. 2 months ago the car started stalling and then it died. Took it to a shop, replaced all original fuel pump and fuel lines. Repeat this about 3 more times, all in all, the fuel pump, fuel lines, map sensor, mass airflow sensor have been replaced. Yesterday, the same thing happened. Took it to a different mechanic, he says he drove it for two days and couldn't find anything wrong with it. Is there anything specific in a 95 lesabre that could be causing this? It drives fine for a while, and then out of nowhere it starts to stall, then the car dies and check engine light comes on. Gas is kept above half a tank due to winter conditions and the fact that it's an old car.
View 8 RepliesCar starts runs rough for a few seconds then shuts off (spark plugs and 2 coils were replaced a few months ago). Coolant reservoir level was way low so I filled to the full line, kept the cap off to cycle. During the time the car starts, the coolant from the reservoir violently "boils" over (out of the reservoir). Huge amount of white smoke from the rear exhaust and a burning smell.
Used Techstream and got the following codes:
Engine and ECT: P0117, P0302, P3190, P3191
Hybrid Control: P0A0F
Intermittently get misfile codes but this time around they did not return.
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 RepliesHaving some problems with my 92 Nissan NX2000. i just finished changing the clutch on the car now its acting horrible.
When i start the car, it will run decent for like 2 or 3 seconds then the idle drops down till it almost dies, catches itself, idle goes up to about 500 were it will pulse around for a few seconds until it dies. If i rev it it will stay running, kept it running for about 2 mins. but as soon as i let off it will pulse at 500 until it dies
After i changed the clutch it started up fine, it ran great for about 20 seconds before it just died. when i started it after is when the problem arose.
I took a video of the car running, which can be seen here. [URL] .... (It has never caught itself like that before and jumped up to 1000 rpms before. It normally will die at that point)
The video is really quiet, not sure what happened there. if need be i can get a video of the engine bay so its louder, was mainly focused on the RPMs.
Here's a few things i tried: Checked fuses, Changed spark plug wires, made sure they were all seated good, MAF wires were rubbed a bit so i cut the MAF pigtail off one of my other sentras and soldered it on,Changed to a good battery, Changed fuel filter, Added more gas (in cause gauge is broken), Made sure all connectors are plugged in, Checked around for vacuum leaks, found that one of the large hoses coming off the intake going to the engine had separated so i plugged them back in and nothing.
Car 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.
I 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.
Trucks been running perfect for 11,000 miles atleast. its last issue was a bad turbo but that was my fault. No issues whatsoever since. 10 miles down the road from work last night truck had a slight miss in between 55-60 for four or five seconds, I put the pedal down and brought it up to 75 or so just to see if it was my imagination and it felt fine so i wrote it off. It ran fine to the house we're working on i wanted to check on before I got home.
Parked it, it idled down to 650 before it came back up to 750 and it never does that and sounded different then it usually does. so i felt something was definitely up. i shut it off, was at the house about a half hour before i decided to head home, started and ran fine, three miles down the road the slight miss came back, it seemed to go away if i got on it pretty good and when i let off but just cruising with slight throttle it had the slight miss.
Got to my road where i had to slow down and turn and it idled down and died. I coasted over, unplugged the icp sensor and it cranked for 10 seconds or so and lazily came back to life. I got it home running decent and parked it. Scanned it with my old super chips tuner and it came up with a p0340 camshaft position code.
Matched my symptoms i felt so this morning i decided id go back to work and grab my spare out of my wrecked truck. truck started and idled perfect. made it to the end of my driveway before the miss came back and then it just died. took the car to work, grabbed my spare camshaft sensor and my maximus scanner, came home scanned it, no returning p0340 cam code but i swapped the camshaft sensor anyway and watched icp and ipr data, the ipr voltage is where it should be and rises while cranking while cranking.
ICP is climbing to almost 3,200 psi and it will begin to run when it peaks out. she'll fire for 45 seconds after 25 seconds of cranking or so and then it'll just die. if it sits for a few minutes it takes a few seconds of cranking before ICP will come off of 0. I've come to the conclusion that it is making high pressure oil it is just dumping it as fast as it can make it. I changed the ipr out because that can do it, it didn't change anything so I'm on to believing an injector is dumping it as fast as possible.
Is it possible for something to come undone inside the injector to make it dump high pressure oil or will a bad o ring cause this? i'm leaning towards a failing injector as when it does fire and run its definitely misfiring and i just put new o rings on them when i swapped them over from my wrecked truck but that was like 45,000 miles ago as well..
I 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 RepliesThe 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 8 RepliesI 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 an issue with my 7.3.... the truck will not start if it sits overnight without being plugged in, even in 65 degree weather. It starts and runs with a rough idle for about 10 seconds after its been plugged in for an hour, after the rough idle is gone it runs great .. it will Stat back up as long as the truck is warm (70+).... I've replaced the batteries, glow plugs, starter (it was going bad) and fuel filter. .. also replaced the gpr today. ....
