Q: 2004 Pontiac grand prix. Tried relearn process for the antitheft, didn't work. What can I do?

asked by on

Relearn process for the antitheft didn't work. Now, everytime I turn the key, the dash lights flicker on and off with a feed-back kinda sound then everything shuts off. It's like a surge. The key is an original. The car has been sitting for almost 3 years. My mother bought it new and always kept a strict maintenance schedule. Never been wrecked or had any problems.

Hello there. It is more than likely that you’ve got a stored error code in the ECU that is causing this problem. The best advice we can offer you is to have a professional mobile mechanic come to your location and have them complete a car is hard to start inspection. They will begin this by downloading error codes and clearing them to see if this resolves your problem.
