will not start, will start with starting fluid but won't stay
This may be related to the antitheft system. The system is known for turning off the starter and/or injectors when it fails. Normally when the injectors are turned off, the car will run for a second or two, and then stall. When it's the security locked out starter, you won't even hear a click when you turn the key. Is there a light on the dash that says SECURITY or a picture of a car with a lock through it? This is a common problem worth looking into. http://www.diy-gm-security.com/ & http://newrockies.com/
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?
