Grand Prix :: 2000 Randomly Dies And Doesn't Want To Start Back Up - MAP Sensor?
Jan 23, 2014
I have a 2000 pontiac grand prix (3.8) and when i was driving my car randomly shut off. When i tried to start it again, the car would start, rev a 1000 RPMs then dies a second later. If i pump the gas i can keep it running at around 2000 RPMs until i let my foot off the gas, then it dies After repeated attempts the tow truck was in need. the following day i ran some tests. when starting the car the fuel pressure would stay between 40-50 psi and doesnt drop below that. (excludes fuel pump, filter, etc..)
After running tests the car suddenly started up and continued to run with the rpm bouncing (+/- 100 rpm) i let the car run for 10 minutes and it began running perfectly. This has happened repeatedly in the past 3 days. I have noticed that when letting the car sit while runnig, it will usually die within 2 minutes, however if I am driving. It will sometimes be fine for hours. When attempting to start it by hitting the gas, the car will sometime sputter at 300 RPMs when hitting the gas will do nothing. in some situations i will hit the gas and the rpms will decrease and rise randomly. (letting my foot off the gas, rpms will hesitate before reducing).
When the car dies, i am at times able to get it running after spending 30 min fiddling with it. But half the time it wont start. I have a -P0107 and P0108, codes for high input and output of the MAP sensor. When i unplug the sensor it seems to have minimal effect to the running condition of the car. When i unplug it at times the car will keep a steady rpm while hitting the gas and the car acts no different when i unplug the sensor when the car is running well. I ordered a new MAP sensor which should arrive today so i can see if that is the problem.

We have a 2003 Grand Prix. For the last few years it has this intermittent problem. Sometimes it just won't start and occasionally it will die while stopped at an intersection. I did some digging online and found out what the likely culprit is, but do not know how to fix it. I already spent a lot of money for a mechanic to claim he fixed it, but didn't.
According to online sources [URL] .... the security system TDM is at fault. It stops recognizing the VATS transponder in the key and thinks the car is being stolen. So, it cuts the connection to the engine. Clearly a dangerous situation if you are driving. My 17 yo daughter recently got stuck in a very busy intersection.
The temporary fix is to turn the key to the on position without turning the engine, wait 10 minutes then try starting the car. This is supposed to reset the security system. Now this is starting to not work. Someone suggested bypassing or modulating the TDM signal by adding in a resistor. I really don't feel equipped to do this though. Another solution is to buy a bypass module.

I have a 2000 Grand Prix with a 3.8L engine that will not start. When I turn the key to the run position, the headlights and the dash lights come on, but when I turn the key to the start position, the lights go dim and nothing happens. No sound from the starter. I checked the battery and the starter and they are good. I installed a new positive battery cable. Still works the same. Not sure what else to check.

2002 Pontiac Grand Prix GT. It's got a NA SII 3800 3.8L engine. So far we have put $337 into trying to fix it. What happens is:
Go to start it.
Turn key to On.
Turn key to start.
It either cranks over a bunch of times and never starts or it starts and dies or it starts and is fine. Every time it wont start after cranking a bunch you give it GAS and it revs up real good and starts fine. Idles at around 1200 RPM. This poor car. There has never been anything wrong with it. Replaced the catalic convertor once and the battery once. We took it in and they replaced the Cam sensor and the Crank sensor to try and fix it because they said the fuel pump registered fine.

I have a 2004 grand prix gt, within the last couple of days, it seems to loose power on acceleration and the motor completely dies at times. After waiting 10 seconds or so it will crank but may die again or just feel like it is loping. The problem is getting worse quickly. I have replaced the fuel filter. This did not stop the problem. I thinking it may be the fuel pump. If it is the fuel pump is there any way to verify this to be sure it is the problem before replacing it?

My 2002 GT 3.8 with 157,000mi has recently and randomly been losing total electrical power after starting the engine. Engine fires like a champ then after 2-3 seconds will completely die- no engine, no lights, no radio, no locks, nada. The key will be stuck in the ignition and can remove it after playing with it. After a time that I haven't been able to determine, electrical power will be restored after I reinsert the key. Sometimes she will stay running after restarting: sometimes not. But she never hesitates to start.
After the first occurrence she ran fine for 3 days but did notice the driver information center would flicker. It never went completely dark, but go from bright to dim- which has previously never happened.
The car has been parked outside and it has been raining quite a bit- I did notice a few times there has been water on the passenger side floor. I had this problem years ago and it was supposed to have been fixed at the shop.
Also of note: I've had the known GP ignition lock issue where the key will not release for the past 3 years. Just been using a pen to manually release the lock from the bottom of the steering column. Don't think it's a battery problem as it is less than 2 months old.

Where the fuse that controls oxygen sensors on a 1997 pontiac grand prix 3.8L engine? i read some where it is under hood fuse panel, but what is the marking for the fuse?

I have a 2000 GP GTP. I went over a speed bump to fast one day, and parked my car. When I got back into the car the next morning, I tried to put my car into drive and it wouldn't accelerate or move. So I put it into lower gear, 1st to be specific, and the car moved normally. I drove like that for a few days with no problem. Then days later I did the same thing, went over a speed bump to fast and now the vehicle wont move at all unless I put it in reverse.

2000 Grand Prix GTP has code P1629, car will run for 3 sec with black master key and then die. Security light in dash is flashing when this happens. Tried the 30 minute relearn for PK3 with no luck. It will start and stay running with the grey Valet key which is perplexing to me. As of right now I am siding with replacing cylinder and ignition switch after everything I've read on the subject.

Cooling Fans and a/c compressor not working-2000 Grand Prix. They both work when I jumper them. Replaced coolant temperature sensor, checked fuses and relays -all good. Not sure what to troubleshoot from here.

Having an issue with my car blowing fuel pump fuses every once in a while under heavy to moderate acceleration. Have replaced inline fuel filter and the fuel pump resister(white ceramic part). Runs fine with normal driving, but when I want to get some horses out of it, it will cut out and stall and once i replace blown fuse it will start back up again, and I'm off and running again.

I have a 2000 Grand Prix 3.8 with 65,000 miles. Bought the car new for the wife to drive. The front brake lines rusted out. My wife has a friend who is a backyard mechanic. She had him replace the front brake lines, from the abs block to each front wheel. Well she finally told me that the brake pedal is not right. I went out and sure enough with pressure on the pedal it goes to an inch off the floor. I bled all for lines at each caliper, no change in pedal. I bled almost a full bottle of fluid. You can pump the pedal for 10 minutes and no change in the pedal. I don't think it is air in the line. I changed the pads and rotors on all four corners last fall. The brake pedal was normal then.

After driving to the store, I parked for like an hour. i came back outside to start it and it just clicks. i bought an starter from autozone, it didn't work. I took that one back and got one from advanced auto, it didn't work either. Again it justs make a hard click when I attempt to start.

Sometimes get a no-start on my car, turn key, nothing have dash lights and headlights, but they do not dim when i turn key, car will also not start in neutral, Had lock cylinder with vats wires replaced, and neutral safety switch was cleaned and adjusted. I even try using remote start and will not with that. this happens every few days or can go a week before problem starts again.

I have a problem with a Torrent. Still have my old GP with over 400K on it. Anyway, son's Torrent wouldn't turn over so he got a new battery and it still won't turn over. I'm getting 12v to the starter but nothing when he tries to start. Have taken starter off to have it looked at tomorrow. In the meantime, anything else it could be? He just spent a small fortune having head gaskets replaced.

It is the 2000 GTP 2 door. It is my sons car and is dead in front of my house. Changed the fuel filter as it is cheap to do. At the check valve there is no pressure in the fuel line. I turned it over with the hose off the filter it did not pump any fuel. I do hear a click or clunk in the gas tank when I turn it over suggesting it is getting power into the pump.
I almost went and bought a pump but do not really want to put the $230 + tax down without checking the resistor after reading around the net.

My 05 GP randomly decides not to start. it turns over well but no fire . Sometimes even when I just stop for gas when its already warm. if I leave it for a few minutes usually it will start, run a little rough for a minute then run fine till next episode. no faults show up. I was thinking maybe the fuel pump relay was acting up.

Yesterday my car ran fine. Today it started running rough when my wife drove it. When I started it to see what was going on it ran very rough. I gave it a little gas and black smoke came out of the tail pipe and now it will not start. I can hear the fuel pump running when I turn the car on. I have spare at least at the coil pack to the wires. The check engine light is on but I don't have a tool to read it and I can't start it to go get it read.

I have a 98 Grand Prix 3.8 with about 170,000 miles on it. Yesterday I tried to start it, and it would crank but not start. Let me provide some background info . . . We had received cold temps and snow recently and the vehicle is parked outside. The car ran fine the day before in colder temps. Yesterday morning I was scooping the snow next to the car and I bumped into it causing the alarm to go off. The horn honked 4 or 5 times and then stopped. Later when I tried to start it, it would just crank. At first I thought it was the fuel pump since I could not hear it. The fuse was fine. I then noticed the DIC was flashing 0 on all modes.
On another thread I saw that is often due to a loss of data between the DCI and PCM. I thought perhaps I tripped the security system when I bumped into it which is preventing it from getting fuel, and perhaps was also causing the DIC to show 0. A GM service tech said to put the key in the run position for 10 minutes then turn it off, and then do this two more times and that should clear the security system and the car should start. I tried it and it did not work. I am starting to think it may be a bad PCM. Stopped at my local Oreillys to check out their code reader, but they no longer check them out to take home. It must be used there.

Drove 28mi out to dinner and when leaving after, she wouldn't start. Took it to work in the morning, and it ran fine prior to that. It was 15degrees outside, added heat to the gastank thinking the fuel line was frozen. Tryed to fire on, but it would only idle briefly surging while doing so and die, like not enough gas. It did start after I held the key down during this surging process grinding the starter also, should have driven home, but I shut it off like a idiot, as a result, had to tow home. Noticed TCS OFF light was lite up while it was running, then I shut it off, TCS OFF LIGHT went away when I turned key back on to attempt a 2nd restart. After i did that, it wouldn't fire on again. Towed to my house, I do not hear the fuel pump trying to kick on when i turn on the key. Fuel system is dry. Cranked over next day and definitely no gas in the lines. Bled the fuel system, no fuel shot out. Have checked the fuse box and the one under the hood too. Replaced the fuel pump relay but still no go just (this blows)...
