A few months ago lightning struck near my 1996 Olds Bravada. Since then my car does not start. Once I open the door or put the key into the ignition all of my dash lights and parking lights start to flash. The buzzer that sounds when you open the door and the key is in the ignition stays on constantly. I replaced the ECM on it and it is doing the same thing still. All of my power locks, seats, and cd player/subs still work. I would appreciate any help anyone can give me on how to solve this problem. Thanks.
