Thanks to all for responding, specifically 88pathoffroad & SEv6. I really appreciate your suggestions. I will try the switch voltage this week. Unfortunately, I do not have the money for a new starter just yet, especially one from the dealer, but I will check out the VIN number idea for now. I'm narrowing it down,...slowly. Thanks again guys!
On to my alarm system spazzing out when the rear gate heats up the sensor in the locking mechanism expands and looses its connection. The alarm thinks the door is open when the vehicle is locked and "armed". I managed to piss off some neighbors lately, but hey it's a big electronic machine and things go wrong from time to time. I read somewhere around here some one inserting a couple of washers to raise the anchor plate and some one else jamming a nail in the locking mechanism itself. Should be a quick fix, heh, heh.
