Just replaced injection pump, glo plugs, starter and batteries. When I get in to to start the truck, the wait to start light flashes on for a second, and goes right off. I can the glo plugs cycle, but the truck will just sit there and crank. is the glo plug controller burned out or what? Iv'e even tried plugging the truck in about 45 min before starting to try and warm it up, but resulted in the same thing.
