If you look at pages 8W-10-9 and the pages that follow, you will get the point - I see no battery supply to the PTCM that does not go thru the switch. Exception would be the "engine control relay" on the RCM. For the engine to keep running, the engine control relay and fuel pump relay would have to be energized and the PTCM would have to be powered up as well. Can I suggest you drop the under-dash panel below the steering column and look at the harness on the back of the ignition switch? I'd suspect that would be the easiest point for someone to have put a remote-start kit in. Also, such kits often use brake or other lights to signal that the system is active - my neighbor had one in the late 90's that, when she held the FOB up to the window in the kitchen and she hit the button, the door locks would lock, the engine would start, and (not sure when in the process, don't remember) the brake lights would flash indicating........... something. Don't remember what now. Hers was an aftermarket kit that a local garge put in. She liked it, never had an issue with it that I know of, but it took the garage 3 days to make it work.
