Hi my name is***** will be glad to try to help. Check all your relays. Try swapping relays with a known good one for test purposes. If the fuses and relays all test good be sure to check all grounds and battery to starter connections. Let me know your complete engine model so I know if this is full mechanical or electronically governed by an ECM. If there is an ECM your ECM could not be sending power to the fuel shutoff due to a fault logged such as low coolant, no engine speed signal, etc. Let me know
Hi Craig, Yes I have worked on a large variety of trucks including these, Fuso's, and the Ford version of these. I'll wait to hear back on the engine model info so I can see if I have the manual for this one. I have several. Let me know
I would have to contact the dealer with the VIN to find out the engine model you have but the tag sill either be on the valve cover or on the side of the engine block. Tomorrow works for me. We can post back and forth as needed
Thanks for the update Craig. Let me know.
Thanks for the info. I happen to have some ECM pinouts and diagrams for this model. Click the link below. Check all your inline fuses and relays shown in the schematic and your ECM powers and grounds
Diagrams and pinouts
Hi Craig, This is the information you are looking for.The SCV controls the fuel from signal from the ECM. If the electrical test good, check for a potential pump issue or low fuel pressure problem. Click this link below
Pleasure to help.
Hi Craig, Thanks for the update. Try this test.
