Working on a 91 Volvo with a series 60 Detroit ddec II. Initially the truck ran 30 seconds an died, swapped out the coolant level sensor and the truck ran great for half the day and died completely. Traced it to a fuel line and repaired only to have a return problem of running 30 seconds before it died out again. Checked the oil pressure sensor and found the harness bare and wires crossing. Patched the wires and truck ran great, for about 3 hours before diving and refusing to start….
