#627 of 980 1992 – Grand Prix Pontiac Cutting Out , Stalling, and Dying Problem
Feb 20, 2006 (5:17 pm)
I own a 1992 Pontiac Grand Prix with 92,000 miles. Car had been running great until recently. These are the symptoms:
Fuel gauge indicator remains lit in spite of the tank being full. Didn't think it was a big deal. The car ran OK.
Drove the car for more than 20 miles, ran fine and it cut off in traffic. The car started immediately.
Drove the car again on a long trip on the freeway, as soon as I took the exit the car acted funny (like it was shaking and making an effort to continue running) it cut out. It started immediately, during the trip, I would have re-start the car and go. Then it died completely. I was unable to start the car again. Had it towed. The mechanic could not reproduce the problem “this dying problem”. Based on the diagnostic test the mechanic replaced the fuel pump and disconnected lock up torque converter system.
The fix did not work and I encountered the same problem. The car had to be towed again. At the shop the car started immediately and again the car would not stall or die when the mechanic took it for a spin. He is now recommending replacing the crankshaft position sensor and module. HELP!
#628 of 980 Lack of Power and Chatter at Idle
Feb 20, 2006 (7:36 pm)
I have a 2005 Grand Prix base and I have noticed within the last few months that when I am driving that the car feels like it has no power(much less than normal). When this occurs if I restart the car it is fine.
I have also noticed that every once in a while when I first start the car after it has sat for awhile, that there is a chatter noise under the hood(I'm thinking A/C compressor).
I am a salesman for an automotive and tire center so I am around cars all day long and I know when things are not right. I have talked to the dealer about the lack of power issue but they said that there is nothging they can do if no check lights are on(understandable). Is any of this common?

This problem is painfully obvious that there is a defect from GM. I would suggest that EVERYONE who has this problem call the GM - Pontiac assistance for customers in the book and at GM.com. I called and they offered some help paying for this "SAFETY" issue. I don't think anyone's insurance company would like to hear that the key is stuck in the car in a parking lot. SO far this problem has ended up costing me $593 after replacing the shift assembly, the ignition, and several silenoids. I also made the dealer write on the workorder, that if the problem continued it would be at their expense 100% to fix it including labor.
#631 of 980 205 GP-GTP Sunroof Noise
Feb 27, 2006 (11:59 am)
Hi all! I'm new to this site after doing a google search to help fix this problem.
I have a 2005 GTP and while I love the car in general, I've been having problems with the headliner and the sunroof shade. I would be interested in hearing from others about their opinions of the quality of the sun shade. I noticed last summer that when the car got warm the shade pane tended to bow downward in the middle. I've also had this annoying creek or ticking sound (depends on the day) whenever I encounter rough pavement. It seems to be related to the pliability of the shade and rigid plastic of the pice you grab to move the shade back and forth. You can push up on the shade and it makes this noise. I'm shocked at how cheap this part seems to be and I had the dealer look at this and they said it was "normal".
Thanks for your feedback....
#633 of 980 Relay will not send power to fuel pump ??
Mar 04, 2006 (8:50 pm)
Hi looking for help / advice from anyone who has encountered this problem.
I have a 98 Grand prix GTP 98k miles. had a new engine put in at 96k miles as the rods went on the old one.
The new problem is: I just had a battery replaced at the dealership, next day the car stopped so they just replaced the fuel pump.
However the car still will not start, AS the new pump is getting no power. I'm being told that the fuel pump relay will not engage, because my Automate alarm is malfunctioning, and will not send an enable signal to trigger the relay.
Now the dealer tells me because of this I will need to have the alarm removed and also need to have the PCM replaced ( cost $3,500 the PCM is in disable mode and cannot be reprogramed because of the alarm)
Has anyone had the same problem, I've had both relays replaced. the relay is a 5 pin relay, the fuse is good it has power, the top pin on the relay gets power.
All the wiring has been checked at the dealership and has continuity, they did a full diagnosis of the PCM and all is fine, except the fuel enable signal to the relay.
Is there some other way this can be fixed short of paying to replace the PCM

My wife has a 2002 Pontiac Grand Prix GT and the key got stuck in the ignition and it wouldnt turn all the way back to the off position. I found a little plastic plug under the steering column that is the size of a dime and pried it off. Then all you have to do is find something long and skinny, I used the inside of a pen ,and push it up there straight while turning your inition back and it should free it. Its some kind of button on the ignition switch under the tumblers for the lock. Now i have to find out how much the dealership wants. My ignition switch is made by AC-Delco.....good luck
