Check for fuel pressure at fuel rail near injectors, if the pressure is good, test for spark with an induction timing light , if there is no spark, check the pickup coil with an OHM meter. if it's open replace it. on a 3800 the coil is between the engine and trans about centered on the crankshaft. one 10mm bolt holds it in, two wire plug. if the engine just suddenly stopped like it was shut off with the key and never started again while cranking strongly start with the sensor first , it's easy to check. my position sensor or pickup coil would read good when it was cold and open when the car warmed up, it had a small crack in it when i pulled it out . some place to start any way, the part was 20 bucks.

See if you have spark at plug from plug wire.
these gm cars have a problem with the ignition module under the distributor cap and rotor button.
when they fail, car dies suddenly and will not restart.fairly easy to replace and not to expensive.

I have a 2002 grand prix gt v6 3.8. The car was running fine then out of know where it wouldn't start. After getting a jump I drove it home and the same thing happend when I tryed to leave again. I can...


Dont have a solution but i have a 3.1 and its doing the same thing. we checked fuel press. and its fine but some one told me that its the fuel pump because if you drive on a half a tank of gas or less the fuel pump is not cooling off properly so it shuts eng. off. cause fuel pump is going bad and it will not show any codes if tested. so i am replacing the fuel pump $260 hopefully this will solve the problem but try driving with full tank of gass it should not do it as often but after about 10 min car should start after it dies.

1991 grande prix 3.1 L turns over but will not fire. I changed the three coils and it is still not starting .


try listening for a noise near the back seat when you first turn the key. if you hear nothing than your fuel pump is not cycling and youll need to replace it. the fuel pump is located on the top of the gas tank and goes down in the tank.

Engine stalling out while driving


It could be that your fuel injection system is failing, try putting some fuel injection cleaner (gas additive) into your gas tank, you should notice a difference after the first full tank. If not it will be time to get your system checked-out at a garage.

Car drives good but it died while driving


I'm leaning toward a bad crankshaft sensor. There's a couple of experienced GM guys on here, so we'll pass it by them first just to be sure.
