I have a 1992 F350 with the 7.3l diesel. I smelled a electrical burn then the engine died. Could not find a burnt wire and noticed the fuel pump was not pulsing, so I ran a jumper to the positive line on the fuel pump and it started right up. Drove it home and the key would not kill the engine until I disconnected the jumper. Does anyone have a wiring diagram so I can find the short? TIA!
