I own a 1989 Pontiac Firebird Formula, my security light will turn on and then the car will not start... I have searched for hours on the internet on how to rectify this problem... Can you please tell me what it is and how to fix it? Or point me in the right direction. -Thanks

Clean battery connections and lightly coat with Vaseline. Check the earth lead on the negative connections has a nice clean bond to the bodywork.

There doesn't appear to be a main fuse, but check on the positive battery lead.

Check all the grounds for the running lights

Buy a ECU from a local salvage and swap them out. It might just work. If not then you might have a short somewhere in the system causing it to shut down.

3m makes a great spray adhe they sell it at walmart for $10 in the auto section , most of the time do it right in the car remove any side trim and spray between liner and board and smooth down.

Yes the security system is doing its job it has shut off the fuel and ignition. Try disconnecting the battery for an hour or so to get it to reset. Good luck. Dont forget to rate.
