Gmc :: Won't Start At Cold - Chugging - Service Engine Light Came On?
Oct 19, 2012
The truck is a 4WD with the 4.8L V8, has 134k problem free miles. While pulling a camper trailer the Service Engine Soon light came on and was blinking. After removing the camper the light went away. Now the light has returned and blinks occasionally. The light is not the larger issue tho. When the engine is cold it is difficult to start and I have to hold the accelerator to the floorboard to keep it running or rather chugging but only on days when ambient temps are below 50ish. As the motor warms it chugs less and eventually smooths out. Once the engine has warmed up it runs as if there is no kind of problem. The service engine light stays on but does not blink. This all began suddenly tho there might have been a problem before but we recently moved to the Chicago area from the Phoenix area. A stop at the local auto parts store for a code read said the fuel pressure sensor is bad tho it seems there is something more than that going on. With a Chicago winter coming this needs repaired!

Twice now (and maybe a third time once I start my van again) we've had problems with the van chugging and then the service engine light blinking. Both times it happened in the past, we took it to a mechanic who said it needed a tune-up - new spark plugs, wires, etc. I'm curious as to why this keeps happening. Mileage is around 105K. It first happened last summer, second time was in December. Now it's March. What could cause this problem to repeat?

On my 7.3 super cab, I changed the fuel filter last Friday and now on cold start the service engine soon light comes on for a couple minutes (approximately) on a cold start. No other issues. Tried scanning with my scan gauge 2 and no codes. (of coarse I think that thing is a joke for scanning). Not sure if this means anything, but last week before I changed the filter I thought I smelled diesel fuel on a couple different occasions. If I actually did it may not even be related.

Prior to the most recent issue with our car the "service engine" light would randomly come on and off. Last week during a cold snap, my husband went into D&D and when he came out the car would not start. Triple A came, said it was the original battery and replaced it.
Then, the next day, he had a dead car after just having driven it, towed it, and the garage did a "hard reset" of electrical system. He drove it no prob for 1 day.
Then, it did not start after sitting in our driveway over night. The car would whirr when the key was turned, lights would go on, but would not start. The garage has done a electrical diag x2 with no leads. They are now going to replace the fuel pump. This seems like a huge leap. However, they said, when they "manually" tried to start the fuel pump it was dead...

My car won't start and I'm trying to figure out why. What is going on. The kind of car I have:
2003 Pontiac Grand Am
2.2L, In-Line4, VIN(F) DOHC
Has about 160,000 on it
Issue I'm having:
Car turns but won't start
"Service Engine Soon" light is on
Tried to jump it (made sure to let it charge for awhile) to no avail
Was low on gas but was not empty -- we filled it up and it still won't turn
Specifically for this model, it is not the Security Bypass issue (where you reset it after 10 minutes)
Recent work history:
On 2/4/14, I took my car to the shop after the check engine light was blinking when I tried to go above 25mph:
Replaced Spark Plugs
Replaced Air Filter
Replaced Ignition Coil Pack
Replaced Spark Plug Boot (Coil to Plug)
Replaced Ignition Control Module
Replaced Fuel Filter
When I drove my car away, the "Check Engine Light" came on. Took it back, this is what they did:
Access computer for codes : "P0172 system to rich on bank 1"
They told me that there was a possible injector leaking down and recommended a fuel injector cleaning. They said I was ok to drive it for awhile and did not have to do it right that moment.
I did light driving on the car but left it in the burbs as I live in the city. When I moved five months later, I brought the car back to the city. I noticed my air conditioning was not working (will blow heat just fine but will not blow cold).
I changed my oil not long after bringing it to the city, in that same month. Besides the air conditioning, I haven't had any real issues and have done local driving through the city.
I took the car out on Friday, drove to Madison, and drove back the next day with no issues (300m trip). This morning we took the car out to the burbs to visit family (20m) -- now it won't start. What it could be?

I have a little more detail on when the truck starts and does not . I have gone out the past two days and put the key in the ignition and turn it to the on position and all the lights come on except Service Engine Soon light and truck will not start. I bought a ceramic electric heater and placed it on the floor directing the heat under the dash. after ten to fifteen minutes I go out and put the key in the ignition turn the key to the on position and the service engine soon light is on and the truck starts right up. I let it warm up for about a half hour and then shut it off. I then try to start it right back up and the service engine soon light comes on momentarily then goes off and the truck does not start?

I got a call from my inlaws saying their truck wouldn't start. Well apparently it had been chugging the day before keep in mind the low fuel light is always on , and they made it home but it stalled and wouldn't start again ran out of gas i imagine he added gas but still nothing , I know with some of these trucks they have a maxi in the tank but would it clog to the point it wont allow fuel to pass ? how do you bring up dash engine fault codes ...
2003 f150 xlt ....

My 1998 Toyota Corolla has 180 K miles. Two days ago I was putting the pedal down to get to work on time and it bucked, began chugging like a motorcycle and the check engine light (which was already on because of an emissions issue) began to flash. A mechanic looked at it and saw that cylinder 3 wasn't sparking. He changed the plugs and wires but the engine was still chugging, especially when idling. The mechanic decided it was a stuck or burnt valve because he said he could hear/feel a lack of compression in the cylinder. I'm looking for a second opinion on the issue, and a first opinion on the mechanic!

I have a 05 f250 with a 5.4 I'm having issues with I was driving along the truck started chugging along and the check engine light came on so I checked it with my bully dog the codes that came up were p0192 which is fuel pressure sensor circuit low the next one is p0452 is evaporative emission pressure sensor switch low also came up with p0191 tonight haven't dug into that yet.
I change out the pressure sensor switch from a buddies truck didn't make a difference put my sensor in his truck his worked fine I clean the throttle position sensor and The maf also put a new air filter on not throwing a misfire code but seems like it may be. A little background on the truck it's a 5.4 3valve with a bully dog tuner, mufflers been removed added straight pipe mechanically that's all that's done

2000 Ford ZX2 2.0 ....I've got approx. 79,350 miles on this car. I'm the original owner. The "Service Engine Soon" light came on. I took the the car to an Advanced Auto Parts store, they hooked up their handheld computer to the car and told me "it might be an oxygen sensor or poor fuel octane", he suggested adding an octane booster and see if the light stays off. I did that,but two days later it came back on, the idle seems a little ruff when stopped at a light.

I have a 1999 F-150 w/ 4.2 V6. and auto trans, truck has 219,000 miles on chassis but only 25,000 on engine and 10,000 on trans. I've been getting obd codes p0705 and p0715. I replaced the position sensor on outside of trans. but I continue to get the codes off and on again. I noticed that the O/D "OFF" light on the shift selector blinks simultaneously when the "service engine soon" light comes on. I've noticed that there is no low gear unless I have it in D from a dead stop, and not even when downshifting manually.

I have a 1993 Toyota MR2 Turbo with about 150,000 miles on it. For the past several years on a cold start (it doesn't seem to matter what the outside temperature is, just that the car has sat for a long time, like overnight), if I try to drive away immediately the car will chug. It almost feels like the car is choking or is not firing. It happens mostly on acceleration above 2500 rpm and in 2nd and 3rd gears, getting worse as you go higher in the gears.
After a few minutes the problem goes away and the car will run fine. Also, if I start the car and let it idle for 5-6 minutes it seems like the car will run fine without the chugging.

2004 chevy cavalier ... when i first start up the car & put it into the drive, it acts like it's going to stall and the low traction light comes on. if i go slow enough, the light will go out, if not both the ABS and NO TRAC and the SERVICE lights will come on. i took it to a repair shop a year ago and they jiggled the wires by the left front wheel and said they'd have to look into it more since I was there for them to just check out the brakes (they were fine). after they jiggled the wires, the problem didn't happen for another couple of months. today i took it to a chevy dealer & they said i needed to replace the left front speed sensor & harness. I just got my oil changed on the way home, the usual warning lights never came on when they would doing the usual starting up and backing out of parking spots. do you think that just a wire is loose and every time i have them look at it, it reconnects?

I have a 2005 jeep liberty 3.7L with 60,000 miles on it. The engine light when on 2 weeks ago and gave a p300 code. the dealership replaced coil and plugs, I believe. Then would start rough when cold, the engine light would blink for about 10 seconds then remain on. the car runs just fine except when cold....first minute of starting it. they checked for head gasket problem, and cant seem to find the problem. They told me that this could just be something that happens. I don't believe that. I have no loss of power, no hesitation. Runs fine 99% of the time

Any way to reset this so it goes out?

I posted about this back when I bought it back in Feb. and I thought the problem worked itself out but its back. When the temperature drops below 55 degrees or so, coming from the passenger side of the engine there is a chugging or knocking sound, more so when RPMs are high.
I had no issues with it all summer, but now that the temperature is dropping I noticed its back. Is this something I should worry about? What could be causing this? I had the same engine in my 07 and it never did this.

My Car: 1989 Plymouth Colt Hatchback (similar to Mitsubushi Mirage); 4 cyl. 1.5 liter fuel injection; 93,000 miles.
Problem: Check engine light comes on & main relay clicks on & off when starting the engine cold. Holding down the gas & keeping the engine RPM's up keeps it from stalling out until the engine warms up. After that, everything is fine.
The problem isn't in the main relay, because we've tried replacing that, and it's okay. Either the engine control computer or something else is sending the main relay a signal to shut down. We know that the engine control computer has gotten wet, and there has been some corrosion there. That's clearly not good, and we're now protecting the computer from moisture, but is that really the problem?
My mechanic thinks that the processor in the computer that controls only the cold starting sequence is no good, and that the only thing to do is get a new computer (if that's even possible). Is it possible that an engine sensor of some kind is not working properly when it's cold, and is sending either the main relay or the computer a signal to shut down the engine?

My service engine light comes on after my camero has been running for a little while some times it takes about 1o minutes before it comes on it runs like there's no problems with it. I know there's a way to check it with a paper clip but I forgot what spots to put it in to get the codes. Its a 1989 camero r/s 305 tpi

I just bought a 1994 s-10. I found out it needed the head gasket replaced, so I had that done. I picked it up last night, and found that when I'm going at speeds over 55 mph, the service engine soon light comes on. When I let off the gas and slow down, the light goes off. The engine sounds fine, and the service engine light has never been on before in the month that I've had the truck. The oil and coolant levels are good. There is no hesitation when going at higher speeds. The only problem is that the light comes on.

I purchased the vapor canister vent valve and purge valve as the service engine light has been on and this are the contributors. I want to know the location of these and how to access. It appears that they may be by the fuel tank and I don't know if I need to lift the box or something to access them. It is the 5.3L V8.
