#68 of 360 ENGINE STALLING AND PROBLEMS STARTING by jagr

May 05, 2008 (12:24 pm)

I HAVE EXPERIENCED ENGINE STALLING WITH MY 2004 PONTIAC GRAND PRIX GT NUMEROUS, NUMEROUS TIMES. WHEN I TURN THE KEY I CAN HEAR CLICKING SOUNDS, BUT IT WILL NOT START. THE WEATHER DOES NOT PLAY A FACTOR IN THIS PROBLEM. I HAVE GAS IN THE CAR, SO THAT IS NOT THE CAUSE. THE CAR WAS TAKEN TO THE DEALER AND THEY COULD NOT PINPOINT THE PROBLEM. WHEN THE CAR STALLS THERE IS NO WARNING. IT HAS HAPPEN TO ME AS I AM IN DRIVE MODE, WHEN I AM ABOUT TO START THE CAR, AND SITTING IN THE DRIVE THROUGH AT FAST FOOD RESTAURANTS. THE TIME OF DAY NOR THE TIME OF SEASON DOES NOT PLAY A ROLE. I HAVE HAD THIS CAR TOWED OVER AND OVER AGAIN. MY 1998 GALANT WITH OVER 170,000 MILES HAS NOT GAVE ME ANY TROUBLE, BUT YET A 2004 PONTIAC GRAND PRIX GT GIVES ME HELL. IT IS VERY DANGEROUS TO DRIVE A VEHICLE AND YOU DON'T KNOW WHEN IT WILL STALL. THERE IS NO USE TO TAKE IT BACK TO THE DEALER WHEN THEY CAN'T EVEN PINPOINT THE EXACT PROBLEM. THE CAR HAS GONE THROUGH EVERY DIAGNOSTIC POSSIBLE....HELP!

I let my 02 sit for about 2 months with the same problem, gassing my exped.every 4 days was to much, so I called the gm dealer asked if they knew what the prob. could be and of course it was the converter, only 700 miles left on warranty, I picked it up today and it has ran wonderful, i even filled up the tank , put 40 miles on it and the gas gauge never moved!!!

#72 of 360 Does ANYBODY have these 2 same problems? by trange1

Can anyone offer me advice about my 2000' Pontiac Grand Prix GT??? (3800 V6 engine) For over 9 months now I have been battling with 2 issues... The 1ST issue is the can randomly WILL NOT start. It will crank but it will not turn over completely. It will happen 1 day and give me trouble for 15 minutes and then 5 days will go by before it happens again. (it just happened today - Tues 5/27) It would not start (but it would crank) for 25 minutes so I left it, came back 1 hour later and it started right up. 2 mechanics later and they cannot figure it out... (a tune up, fuel pump is good, wiring harness replaced, fuel sensor replaced, etc...)
 
The 2nd issue is a major hesitation problem which is ALSO intermittent. I will stomp on the gas and even though it still accelerates, it feels like it hesitates and almost sputters. It's strong enough to actually "feel it" when it happens BUT yet there are times when I stomp on the gas and the car accelerates just fine. It's kind of scary when your passing someone because it doesn't feel like the power is there that should be.
 
Thank you for taking the time to read this and even replying to this post if you have any answers. I can clarify both issues with more detail if necessary.
 
Thank you again...

I am from Michigan and it appears that we have the SAME problem and the SAME car. My message post # is 72. I just joined this forum. My car has never stalled BUT IF I hear of anything, I will definitely let you know by replying to your post again. IF you get a chance check out my message post and reply if you want to. I'm not giving up so I WILL find an answer eventually...
 
Thanks

I too have this problem. It is said to be the CPS (crankshaft position sensor) I'm having my replaced next week. This can be tested at a dealer to confirm. As mine was found to be faulty when warm. I have heard others replacing it, and solved the problem. I just hope so.

It was not the CPS (crankshaft position sensor) but the throttle body and plates were gummed up. Cause...K&N filter oil got into the MAF screen and coated the intake.. Total cost at a dealer to clean $145.00 Replaced air filter and so far car is running better. I can only hope this was it.

Did you ever figure anything out? I have a 2004 also and mine does the exact same thing?

It's been a week, and car has not had a no start or stall. Dealer stated maybe the CPS (crankshaft position sensor) but found I had a K&N filter, and the throttle plates and screen was coated in oil from the filter (it was pre oiled) had everything cleaned and went with FRAM paper filter, so far so good.
 
Note..GM discourages use of K&N filters for this reason, unless you very lightly oil the filter. And cleaning the Thottle plates and throttle body at least once a year.
