99 Silverado won't start
Replaces fuel filter, fuel pump, fuel pressure regulator,
crank shaft sensor, cam shaft sensor, and computer, still
will not start, will start with starting fluid but won't stay
The security light only comes on after 5-10 seconds if the key is in the on position with engine off... But then turns off after a couple seconds... I also have a little black button in my fuse box by the steering wheel, if I push it the truck beeps and the little red light by my steering wheel stays on, if I push it again it beeps again and then the little red light starts to blink... How do I know if the anti theft system has failed?
