The only things left is the oil pressure switch and pickup coil in the distributor. Those have a great deal in operating the fuel system for the truck. The oil pressure switch gauge is the bypass for fuelpump operation. But the pickup coil inside the distributor would be the main problem behind operation of the fuel operating system. If the computer is sensing no signal it shuts down the system.
