Hi I have a 2.0l 1997 Galaxy. Had problems starting. Engine turns over but will not fire. Then everything is ok after 10 mins wait. Starts ok in mornings and only a problem if i stop somewhere and need to restart. Wait 10 mins and everythings ok. AA man said it was key or lock housing on steering not sending signal code somewhere. I can tell if it wont start because light on door panel flashes constantly. HELP
