Grand Prix :: 2002 Pontiac - Gauges Flipping / Air Bag Light Flashing Now It Won't Start
2002 Grand Prix, 3.8L na motor, 187K miles. It was running perfectly until 4 days ago. initially, odd gauge stuff and flashing air bag light, then very, very slight engine skip with the tach gauge flipping around. 2 days ago, harder than usual starts ( a couple of seconds cranking instead of instant starts ), 1 day go, longer cranking in the morning, worse stuttering at highway speed. Afternoon, very hard start, stuttering right away, and then it would hardly start and quit after seconds. Gauges flipping and relays buzzing under the dash.
I had it towed home. Moving the key to run I didn't hear the fuel pump running. Checked the pressure at the rail, zero pressure. I removed the relay and jumped it to run the pump at high pressure. Fuel pump ran, pressure was 50-60lbs. Reinserted the relay, tried to start it and no change. I couldn't hear the pump running. Removed the relay and jumped the pump again, left it running and tried starting the car. Also no start.
I'm thinking it may have something to do with the ignition switch, PK3 system, BCM or PCM although I'm not sure which way to go with testing. I'm going to re-check the fuel pump and then start taking ignition switch out.
Grand Prix :: 2002 Pontiac Speed Dropping On Highway - Temperature Really High On Gauge
One day, I was on the highway and my Pontiac's speed started dropping. I looked at the temperature gauge, and the temperature was really high. I flushed the coolant system, and changed the gasket. Also the mechanic said that the oil might be leaking after they changed the oil. I paid like $700 for something that has nothing to do with the problem (I paid for a spark plug, ignition wires, fuel filter, and an oxygen sensor). After they changed the oil, oil started leaking all over my driveway, which didn't happen before. It also looked like coolant was leaking out. None of this happened before I got my oil changed with these guys.
After I changed the gasket, the car was running smoothly. But today, the same thing happened again, and I don't know if it's the thermostat, or water pump, or oil leaking, or coolant. The mechanic always suggests to fix something that doesn't have to do with the problem. I don't have much money on hand, so I need to only fix what has to do with the temperature rising, and I need my car to run.

I have a 2005 Pontiac Grand Prix V6 and for some reason my washer fluid sprayer just stopped working. Yes, the fluid is full...hahaa. So anyways, I checked the fuses and they seem to be ok. What I can check before tearing it apart or bringing it in? How do you know if the motor is bad? Where is the motor located in this car? The wipers are working fine, but it'd be nice to clean the windows.

I have a 91 pontiac Grand Prix with a 3.1 and the car has NO leaks, however, I have noticed that the transmission fluid level go down and the engine oil goes up. My conclusion is that some how the tranny fluid is crossing over to the engine, is this possible? and if it is, how or where?
NOTE: my car has a tranny cooling line to the radiator but no engine oil cooling lines and the colant is clean. how is it possible?

View 2 RepliesGrand Prix :: 1999 Pontiac Won't Start / Idle Briefly Surging Like Not Enough Gas
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)...

With summer heating up so is the engine. Temp stays normal at freeway speeds but as soon as I hit stop and go traffic it shoots up. Water pump is two years old. I flushed the radiator and didn't get much gunk out. Both fans are running when the AC is on. If I shut the car off but leave the key on the fans do not run when the car is not. I can't remember if they used to or not.

Pontiac :: 2003 Grand Prix Intermittently Won't Start And Sometimes Dies While Driving
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.
Grand Prix :: 1999 Pontiac - Temp Gauge Will Float Up And Down After About Five Minutes Of Drive
I have a 1999 Pontiac Grand Prix. The needle on the temp gauge will float up and down after about five mins. of drive time...after a short period of time, however, it will settle around 200 degrees or so. (The heater will not blow warm air while the needle is floating.) The only time the needle starts to rise is when the vehicle is stopped in traffic, but even then, it never gets into the "red." The car never overheats and I have yet to see any coolant on the driveway.

I just changed my fuel filter and now I am having issues with the idle/accelator. When I get the car going to a speed of 40mph for example, I let off the gas and the speed barely drops. Then when I went down a side street about 20 mph, I let off the gas and the car just kept going. The idle was initally high, but then dropped down to it's normal 800rpm.
The only thing I touched under the hood was releasing the pressure from the fuel pressure regulator before the fuel filter change. I just removed the idle control unit and cleaned it but that didn't work.

Grand Prix :: 2004 - When Turn Key On It Will Not Start Or Even Turn Over
My 2004 Grand Prix has a intermittent start no start condition. If I turn the key on and the radio and dash work it will not start or even turn over. Most times when trying to start it the only light that turns on is the check engine light. Some times I have to turn the key off and then to the start position a dozen times before the starter will engage. Then it runs normal and can be driven but the entire dash does not work except for the check engine light. At this time the radio and information display do not work either. Everything else works as it should. I cleaned the battery connections and installed a new battery. I also tried a new Ignition switch. Checked all my fuses and they seem to be good. Cleaned the ground below the battery and the two on transmission. I can always get it started but it would be nice If I could tell how fast I am going. Maybe try bcm next.

Grand Prix :: Torrent Wouldn't Turn Over When Try To Start Up
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.

View 1 RepliesGrand Prix :: 2002 Starts Then Dies - Idles At Around 1200 RPM
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.
