I've got an '88 with a 1 month old rebuilt 350 TBI. This problem was around before the rebuild and it's driving me insane! /forums/images/graemlins/angryfire.gif When I take the truck out short trips I wont have any problems. But when I have to drive for a good 30 minutes or more in the Florida heat, I'll park the truck for a minute, then it won't start. I mean nothing, no crancking, no sound, nothing. It's not the battery, because after cooling down for a 1/2 hour it'll start right up. Someone mentioned that it might be the coil, so I changed that out today, but is there something else that would cause this? /forums/images/graemlins/confused.gif I just don't want to be left stranded again in this heat. /forums/images/graemlins/k5.gif Any advise would be greatly appreciated.
