Hey on my 02 f350 my starter when the ignition is OFF. Just ramdomly cranks the vehicle. I had the truck sitting their for 3 hours and while I was landscaping my yard it just started to crank again. When I came out of the store I had smoke rolling out from under my hood because the starter was stuck on for so long. 5-10 minutes. I have already completely disconnected my remote start alarm, and swapped my starter relay. It still tries at time to start itsself. Any Ideas. I am thinking ignition switch.
