By-pass the anti-theft . Videos on youtube showing how too . How to troubleshoot bypass GM VATS Passlock Passkey System

try disconnect battery for 30sec.

If you turn the key to the on position do not start the car and you have
no security lights that come on then it may be your ati-theft system.
to try and reset it just leave the key in the on position for ten minutes
or more or until you see security lights on the dash.

the anti-theft has been activated and will have to be reset.

Repair the anti theft system as car thinks you are trying to steal it.

have ur battery checked first if battery charge is fine then have a car electrical system malfunction....

I have a 97 Malibu and when the theft system light kept coming on and would only start after letting the car sit for 10 minutes we ended up replacing the complete ignition where the key goes in. Then it was fine. It wasn't cheap either. Sorry, good luck.

Tell the guy to call the dealer and ask them how to override the anti theft system or reset it. when you disconnect the battery and lose power it kicks on the anti theft device and it won't get fire.

i changed the motor and tranny on my gt and the theft system was on. put key to on potion and leave for exactly 5 mins no more no less then the theft light will go out and start it. took me forever to find that out

turning left and stalling sounds like your power steering pressure switch is bad.as for other problem try unlocking drivers door using the key this should reset the factory alarm. also make sure you didn't miss a wire when reconnecting bat. look for 12gauge red wire near bat. this goes to computer if not connected car will crank but not start.
