Check your fuel pump pressure. An easy way is to crank the car over and then loosen the bleeder screw at the end of the fuel rail (assuming it's common-rail fuel injected) and fuel should squirt out. If it doesn't, you have insufficient fuel pressure and should first change your fuel filter, and if that doesn't work replace your fuel pump relay and then finally your fuel pump. If fuel does squirt out, check your throttle body for proper operation.
If the engine stops running when the key is released, then the ignition switch is probably bad. The switch will need to be replaced.
The fuel pump keeps running with the ignition off because it needs to be replaced. ?æThere could possibly be something wrong with the wiring.
sounds like the ignition control module
The lock/tumbler has to be in time with the ignition switch. I suspect it is not.
day time running module on drivers fender back by the brake booster needs to be replaced
The blower resistor is internally shorted to power and needs to be replaced.
I had a problem with my 1999 silverado bacause of a faulty fuel pump it was causing my truck to cut off after running for a minute or two. After getting under the truck and listening to the fuel pump whine I was then able to determine that the pump was in need of replacement. The truck runs great now that I have replaced the pump. I didn't know what to do for my truck to get it running right so I replaced ignition coils, control modules, and even straight wired my ignition so the relay's wouldn't cause my truck not to crank properly.
Quit running after its fully up to temp? Restarts after it cools down? Check the spark when it does it, could be the ignition control module.

just found out that it needed a fuel pump. engine was flooded and needed to dry up.
Go ahead and replace the pcv
its located on driver side head on top of block little black module with plugwire running out of it
