if the vehicle starts then stops and the anti-theft light is flahing you may need to re-set the pass-key system to do this you will need to atempt to start the vehicle and when it stalls leave the key in that position and watch the anti-theft light. it should flash on and off for about 5 to 10 minutes. when it stops flahing turn the ignition to off then try to restart your vehicle

SOURCE: 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.

2004 PONTIAC SUNFIRE REPLACED ALTERNATOR NOW STARTER CRANKS BUT WILL NOT START


I had the same issue!! it is the security system failing. I took it to the shop and they wanted a ridiculous amount of money to fix it.. So i did a ton of research and i found a part you can install yourself that will bypass it allowing your car to start every time... I did mine 5 years ago and i havent had an issue since. Check out the site your car in on the list year make and model.. They are friendly and have great customer service and for some reason if it doesnt work they will refund you 100% hope this helps ya out

I changed the steering column on my 95 sunfire and will start but due to the anti theft system the fuel injectors are almost instantly making my car die. how do i change or reset passcode on the...


I'm going to assume your Sunfire 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 bring up results 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.
