I own a 2003 Saab 9-3 Linear. It was in a small car crash and ive replaced the bumper and the fender which were broken, but since the accident the car refuses to start. When I turn the key to start it, all the lights come on like normal and there is power, but the engine is not responding to the key. Is there some kind of inertia switch that stops the engine from turning on after a crash or any other kind of safety device that may be causing this. Cause i know that the engine works and it was never touched in the crash, nor any important equipment.
