Truck Repair: Powerstroke diesel, camshaft sensor, pressure oil

Question
"I have a late 94 powerstroke in a 350 ford. I drove it down the road about a quarter of a mile and stepped on the clutch to down shift and the motor quit. I can't get it to start again When I crank it it won't even smoke. The starter is new and the batteries are new so it cranks fast. When I checked the fuel filter the pump was filling the fuel filter and it had pressure at the test port. The wiring harness is new the gaskets and glow plug are new and the motor run smooth previous to thi problem. I tried changing the camshaft sensor on the front cover and that didn't help the problem . what would be your next suggestion.


Answer
I have to say it looks as though you have all the basics covered.  Some of the other items involved in the starting process are the high pressure oil pump, the IPR(injection pressure regulator), and the injection pressure sensor.  These are all tested by the used of a diag.computer.  I have to say you are to the point you need to get the truck hooked up to a computer and see what it comes up with.  Let me know if I can be any further help.
