Last week I started my truck in the morning and it started right up. When it had ran about 45 seconds, it stopped running. I then cranked it for about 30 seconds and it tried to start, but would not. I then changed the fuel filter and cleaned the prefilter. They were a little dirty,but not enough to stall the engine. I then purged the air out of the filter and restarted it. Ran about 1 minute and died. I have rechecked every thing and have fuel to the injection pump, but no fuel from the high pressure side. I have the fuel shutoff lever disconnected from the solinoid and held in the run position. Any ideas, Thank you, Tom
