Won't start unless unplug and plug computer

How many miles are on it? Could be timing chain wear.

The gas u put I'm the tank was high octain if it was it was making the engine fire to early replace the gas and it should wor properly

If I crank the motor while it is st ??????? Probably ignition module . When it shuts off check for spark .

has base idle speed and kurb idle speed. allows engine to close throttle opening when shutting down to stop pre-ignition or engine running on

Try getting your transmission solenoid replaced. After I got mine replaced it ran fine after that. That's the exact same thing my Lumina was doing.

Hi Rachel, Have you had the cat checked to find out if its blocked? The symptoms you describe are of a build up of pressure in the exhaust system which inhibit the intake and kill engine. Regards John

Can you jumper the fuel pump and make it start and continue to run ?
Have you checked to see if you are getting spark when it won't start ?
Could be a relay or coil, ignition module, or other component.

I had the same problem. My car sat for a few days and when i went to start it i heard an extremely loud pop (kind of like a backfire). After that it would start and sound fine, but die 2 seconds later. Thank god my bf is a mechanic he knew instantly that the pcv valve hose that connects to the intake manifold unplugged itself. He plugged it back in and it runs fine now. I didnt however get a check engine light, but i only tried to start it twice before he fixed it because i was scared it jumped time.

sounds like a problem with the ignition barrel.the wiring is loose or the connectors are loose or the barrel is faulty,unless thse are all run from the onboard computer.

It could be a number of things. Have you tried to run any codes yet?
