Sounds like a problem in the High Pressure Oil System. Have you unplugged the ICP sensor and see it if will start? It may be a failed ICP (Injection Control Pressure) Sensor. It may be an IPR (Injection Pressure Regulator) Sensor. It may be an o-ring on the pump, or the HPOP may have failed. It needs if I remember correctly ~500psi to start. If the ICP or ICR has failed, and you unplug the sensor it may start as the PCM will run the pump at a failsafe level and you may be able to start the engine at that point.

Exatcally, what codes are you getting? Please give the code numbers, that can help alot.

I hate to ask the obvious questions, have you checked the oil level? Just a few quarts low can cause a no start..... How many miles on the truck, any mods?

Do you have any "new" oil leaks, and if so where?
