Problem: The engine will crank but not start. The MIL was not on and there were no DTCs.
Details: The technician verified the engine will crank but not start. It had spark but no fuel pressure. He verified voltage on both sides of the fuel system fuses, swapped the fuel pump relay and tried replacing the fuel pump. Still, there was no fuel pressure. At this point, he called ALLDATA Tech-Assist.
The ALLDATA Tech-Assist consultant suggested that he check for power and grounds at the pump. The technician found no voltage at the fuel pump (Circuit A61). He traced the circuit back to the fuel pump relay and found the circuit was open about 10 inches from the power distribution center.
Confirmed Repair: He repaired the wiring and the truck started and ran normally. He also rechecked the fuel pressure. It was at factory specifications.
