Welcome to the forum. Always begin with a diagnosis. Any 'click' or dimming of headlamps when the key is moved to the 'start' position? Tried starting it in Neutral? The PRNDL display in the cluster has the P boxed?
Is the car equipped with Remote Start, factory or aftermarket? Any aftermarket alarm/security system?
Has a scan tool been plugged in to look for fault codes? A good scan tool can tell you if the 'key-on' signal is reaching the PCM or TIPM.
