Please do not ask people to email you directly with answers. Part of the reason these forums are popular is because solutions from other users can be found. If someone emails directly with a solution, no one else benefits from that.


There is no reason for auto shop owners to be stumped unless they can't duplicate the no-start condition. If an engine won't start there has to be a reason. No compression, no spark or no fuel. When the truck won't start, check these things.
