Grand Prix :: 2000 With 3.8L Engine Won't Start
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.

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.

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.
Grand 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)...
View 7 RepliesPontiac :: 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 :: 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 :: 2000 Randomly Dies And Doesn't Want To Start Back Up - MAP Sensor?
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.
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.

Sonata NF (2006-10) :: Car Is Not Starting After Parked For An Hour
OK, so I was gone for about a week and my Sonata's been sitting in the basement the whole time. When I went to start it this morning, the starter spins for about two fires then stops. I release the key, try again and it's fine. Once I got to work, I killed it then started it again and it was fine. I'll be heading home in about 30 minutes to see if it does it once again. It shouldn't be due to the cold; it's about 50-60*F in the basement. It turned over just fine, so it wasn't battery or power related. I'm hoping it was just some kind of fluke, but I'm also paranoid after seeing the recent surge of Sonata problems.
Oh yeah, and last time I went on a trip both my cars had problems. The Sonata had a leaking tire and the Jeep had a failing alternator. Now my jeep gets backed into while at the parking lot and my Sonata doesn't start the first try.
95 Grand Prix Ignition Cylinder - Cannot Turn Key

View 1 RepliesGrand Prix :: 99 GTP - How To Lift / Hoist Engine Out
I'm pulling the engine to overhaul. I've borrowed a hoist and think I'm ready to lift the engine out, but I don't know how to strap the engine to the hoist. I first thought of using the brackets with the eyelets bolted to each head and bought chain and hooks. But I had to remove the rear bracket so I could remove the rear exhaust manifold so I could remove that darn rear engine-transaxle bolt. (That really bites because I want to have the exhaust manifolds on when dropping it back in.)
Are those brackets intended for lifting the engine? If so, I could reinstall the back bracket and give it a go.
Searched the internet for info but didn't find much. Did find a 3800 being lifted with two straps completely under the engine.
Also, the engine-transaxle joint hasn't cracked open yet. I'm guessing it's because they're stuck after 198k miles and will eventually separate. But I did not find one of the engine-transaxle bolts mentioned in the 98 FSM: front lower (#1). I don't see how I could have missed it ; maybe the 99 doesn't have it?

View 2 RepliesGrand Prix :: 2004 - RPM Will Drop All The Way Down And Stall
When you are accelerating anywhere from half to full throttle it may cut out at any given time. The RPM will drop down, it may bounce up and down for a bit and recover, or it will drop all the way down and stall. If you let off the gas it may or may not recover. If it stalls so far from the tests I have done if you never shut the key off it will never restart again. If you shut the key off and wait from 5 to 10 minutes it will all of a sudden restart normally like nothing ever happened. If you try to restart it immediately even if you shut the key off and back on it will not start.
When it does not start when I am attempting to start: Fuel pressure according to my gauge is between 55 and 60 psi. Inline spark tester shows that it is getting a spark. Engine sounds normal while cranking so in other words compression sounds normal. I have an LED test light rigged up showing when an injector fires, and it does show electrical activity going to the injector when it opens (flashes). Only clue is that it SEEMS dimmer when it wont start, but I have no clue if thats how it normally is on start up. Its only a slight difference from the brightness of a normal idle brightness. I have a snap on scanner hooked up, nothing that I know of looks abnormal in the data and it will not throw codes when this happens.
Parts I have changed or cleaned so far: Changed the fuel filter, crank sensor, cam sensor, ignition module, and MAF sensor. Cleaned the throttle body. When the car is working normally it runs strong, good power, smooth. Starts great normally.
Grand Prix :: Harsh Shifting From 1st To 2nd And Then From 2nd To 3rd Gear
What may be causing my car to harshly shift fron 1st to 2nd and then from 2nd the 3rd. One solution some one had was to replace the:
"TPS (throttle position sensor). The other reason for hard shift is a worn Boost valve and will need to be replaced, or a faulty transmission fluid EPC (electronic pressures control valve). Both Boost valve and EPC are located in the Valve Body and can be replaced with out dropping the valve body, but have to drop the transmission pan".
I did just recently top off the tranny fluid because it was running a bit low but there is no leak....
