I have 94 3.1se with same problem. Starter will click periodically and not start, play with key, shifter, security lock then it will decide to work (sometimes), this has been an ongoing problem for a few years. Seemed to be a starter issue - Pontiac dealer changed starter 2 times, my mechanic thought it was starter also, changed starter again; problem still re-occurs after short period of time. After checking the web have noticed others with the same problem. Checked different forums on the web and found someone who said it was a control module reset problem due to a weak battery. Replaced batt. on July 5th, car has not had problem since. Hopefully cured!?! In your post you stated "idles little rough under load of turn signal". I have noticed a difference in my idle when turn signal is on also. Maybe electrical ground draining batt. during turn signal op.?? Love my GP 94, runs great dispite starting problem have 206k miles and still going like a top!! Good luck with problem. Also curious if anyone out there has a solid answer to this problem.
#90 of 367 1998 Grand Prix GT (3.8L) stalls after starting
Jul 14, 2008 (3:22 pm)
My 98 Grand Prix (145k miles) failed to start, happened with no warning, in between errands. The engine would start but immediately die. Giving it a little gas to keep it going sounded like it was running on half the cylinders. Had to have it towed to a local repair shop (had been there twice before over the years when the battery went dead out of the blue). The shop called today and said it was a bad Air Flow Meter, $350 part !! I browsed the forums but no mention of an Air Flow Meter. (may be called something else?) Does anyone know what that part is? Sound familier?
Coincedently two weeks ago I had the car in the shop (dealorship, not the same place it is now) for routine maintence and state inspection, that incuded replacing the air filter. Is this AFM located in the area of the air filter?
Appreciate knowing if replacing the part will fix the problem or could it be something else that will pop up "out of the blue" again?

Do not know what an Air Flow Meter is, maybe they are talking about oxygen sensor failure which is a common problem with many cars.
#92 of 367 2000 grand prix starting problems
Jul 16, 2008 (7:49 pm)
i have a 2000 GTP which is having starting problems. We went shopping and came out of the store, put the key in and when I turned the key i can hear a click that sounds like it comes from where the fuse box is. We took the starter off and had it tested and it is perfectly fine. The starter does not even attempt to turn when the key is turned but it is getting power. I think that there is a relay inbetween the ignition switch and the starter but I am not sure if that could be the problem. it is possible it is a fuse but once again I am not sure which one, can anyone help me???
#93 of 367 Pontiac Grand Prix Starting / Stalling Issues
Jul 17, 2008 (9:25 am)
I previously posted a message about my 04'Pontiac Grand Prix GT. I came to the conclusion that my car could not be completely fixed so I GOT RID OF THE S.O.B.! It felt really good to know I will never have to deal with the drama again. You know when your car is towed more times than average and you have certified Pontiac mechanics constantly working on the car telling you this and that needs to be replaced each and every time....hundreds of dollars adding to thousands....thinking your car is fixed...but, again the car starts to have the same issues...STARTING OR STALLING all over again. Your driving down the highway sunroof open...listening to your favorite music....Shittttt....the car stops(stalls)...luckily I was not in a fatal accident........You are at the store.....you go to start the car......Shittttt......the car will not start.....how humiliating is that....FYI if you continue to start the car over and over again the starter will get hot and burn out and will need to be replaced...more money to dish out.....I think the cars are made as a money trap.....the car owner contiunues to dish out money hoping this part will fix the car or get this or that part cleaned out and the starting / stalling issues will go away....HA!!! GET RID OF THE TRASH......THAT'S THE ANSWER TO YOUR QUESTION. AND NEVER BUY A PONTIAC AGAIN....the problem seems to be the same for different models......
Best Regards and GOOD LUCK with your Pontiac!
Oh yeah....when I turned my defroster on the fm signal would go out and when I made a left turn the car would make a weird noise each time...as if something was going to break in pieces.
#94 of 367 02 grand prix wont start
Jul 22, 2008 (11:07 am)
I change the engine on my 02 grand prix, put in a used one, reconnected back to original and now it wont start. I disconnected the fuel lines and there's plenty of pressure, but when i crank it, it sounds like its not getting any fuel in the combustion chamber. Maybe there's a fuel shut reset somewhere, but I cant find it. Can anybody help me with this problem. I'll be looking for posts, thank you.

He may have been referring to the Mass Air Flow sensor. The MAF is typically installed between the air filter and the throttle body. It senses the volume of air moving thru the throttle body and tells the computer how much fuel is required for the proper air-fuel mixture. It is one of the critical components in the intake system. It is possible that it was damaged, or an electrical connection was loosened, during the changing of the air filter. It may be dirty and just require some cleaning, but be careful; they are easily damaged. Good luck. Clark

I have a very similar thing going on. I have checked fuel pressure, it's approx 40lbs, the injectors ohm in about 13 or14 and I have good spark. It turns over but will only start if I spray starting fluid into the plenum. I have checked for error codes, it had a prior IAC code so I replaced that and the TPS sensor. No codes, but no starts either
#97 of 367 Re: Does ANYBODY have these 2 same problems? [trange1]
Aug 03, 2008 (5:09 pm)
I had a problem with my 1999 Firebird with the 3.8L V6 not starting, which I am having the same problem with my wifes 2004 Grand Prix not starting. Anyways, the problem with the Firebird was, it would start fine when it was cold but after being warmed up it would take a few cranks to get it to start and it would also backfire when letting off the gas. I took advice from the shops and other mechanics over about 9 months, changed crank sensor, coolant temp sensor, o2 sensors, checked the ignition wires, spark plugs, fuel pump, fuel pressure etc... everything checked out fine. I had no trouble codes other than 1 misfire from #2 cylinder. After it was cleared it never came back but still had the same problem. So finally I thought about it and went ahead and changed the fuel pressure regulator, even though the pressure was within tolerance with the engine off and the engine running. It fixed the starting problem and the backfiring problem, which hasn't came back yet. It took less than an hour to change, still a pain on a Firebird since I had to remove the fuel rail. But on a front wheel drive it should only take about 15 minutes with a pair of lock-ring pliers and about $50 for the regulator. I'm not saying this will definitely fix your problem, but with it happening to my wifes car after about 50,000 miles, its the first thing I am going to change.
#98 of 367 1992 Pontiac Grand Prix
Aug 04, 2008 (2:23 pm)
. The car is a 1992 Pontiac Grand Prix, loaded with options, including power windows, heads-up display and the radio controls on the steering wheel. The car was originally my brother-in-laws. He purchased it from a friend at the chevy plant where he worked. It was originally a friends wifes car and she passed away. So the vehicle was never hot-rodded and is low mileage at 68000. It sat alot. The problem started with the car dying at stop lights or signs. At first it would restart, but after a short period of time it progressed to the point it had to be towed home. It now fails to start at all. I have checked the fuel log, it has 40psi fuel pressure. The injectors ohm within 1 ohm of each other at 13 or 14 ohms. With a Fluke multi meter it reads .6 volts at the injectors. The ignition has good spark at the plugs, bright and blue. I hooked up a 12v bulb across the injector harness and the bulb glows orange/yellow, very dim but does flicker like it's receiving a pulse to spray. If I spray starting fluid or even gas into the plenum the car will start and run briefly. I have looked at the schmatic for the engine and I don't see anything upstream from the injectors except the ECM. Someone advised that with the car sitting as long as it has the injectors could be gummed up, and failing to spray. Someone else mentioned a "passlock" which I am not familiar with. I'm getting what is probably good advice, but I'm still chasing my tail. Is there another componet that controls fuel discharge?
