Car is 2003 grand am gt 3400. When it starts it runs fine. The problem is most mornings it doesn't start and thats due to it not getting a spark. Later in the day it always starts fine. If I leave the car on for like 5-10 minutes after it not starting it will get a spark and start up. I have to leave the key on for it to work though. I know there is a security issue with these cars but I don't think that's it because it goes off right after I turn the keys on and its not flashing. Plugs, wires and coils are good. Both crank sensors and ICM are good. I'm lost now.
