I'm going to assume this has the VATS system with the pellet in the key. You need to know the correct resistant of the factory pellet and bypass the system using that value. A quick google search will result in many articles on how to bypass the VATS system, as it's required when installing a remote start system in most late 80s-mid 90s GM vehicles.

I have a 1999 pontiac sunfire with a remote start. Sometimes when I push the remote to start my car, it will start and shut off right away and the anti theft light will flash. Is there something that I can...


no but what you have bad is your remote start brain box that is triggering the anti theft. i suggest taking to a auto electronic place for servicing or stop using remote start.

Alarm sytem triggered


You cannot since the anti theft system is integral to the ignition and fuel delivery systems.

Sorry.

You may have a faulty ingition. Otherwise you have the very common GM anti-theft system. If you have a flashing anti-theft light with key in igniton, then this is what you should do:

Put key in ignition, turn to ON position (Do NOT Start)
Leave in on position for EXACTLY 10 Minutes
Then while watching the anti-theft light, as SOON as the light turns off after 10 minutes, START CAR IMMEDIATELY after light turns off.

This will reset the anti-theft

How to remove or bypass the factory installed anti theft vehicle immobilizer.


in the 1996 sunfire GM uses an anti theft lock system. It can be triggered by all sorts of things. In order to relinquish this you must have a key to turn the ignition. These are not coded just plain cut keys. Once you attain this you put the key in and turn the ignition to the ACC position and wait ten minutes (theft lock light will turn off), turn off and take key out. You MUST do this 3 times and then the theft lock will be disarmed.
