01 PSD shut down and will not restart

My buddy said he was coasting down to a red light and she just shut down on him with no warning, just like you turned the key off.

Here is what we have tried so far;
Swapped CPS
Swapped IPR
Swapped IDM
Listened to fuel pump and checked fuel filter bowl
Hooked predator to computer and watched engine RPM and ICP and a few others

We noticed that the ICP when cranking read 15MPA with the ICP un plugged and sometimes 0 and sometimes 15MPA with it plugged up. We also noticed the HPOP reservoir was empty so we refilled it with no change. Im thinking the next step is to rig up a mechanical gauge and check the oil pressure to see what it is while cranking.

My next questions is if the oil pressure is not there while cranking what could cause it?
Im thinking maybe an injector went bad and is not letting the pump build pressure, is that possible? What would cause the HPOP reservoir to run empty? Any other likely culprits?

About 2000 psi according to convert.

Engine oil is full of Rotella 15 40 and is changed on a regular basis.


We did get to have a little redneck fun in the process though, Thank goodness it was down hill.

have you checked the wiring harness under the valve covers for damage?

I wish I could help a little better. No cranking at all is a bit baffling. I would assume no fuel, which it appears you have as well. The question is why. I'm surprised the HPOP reservoir was empty. That's three quarts of oil up there. I'm not an expert on how the oil, fuel and such is delivered so I'm not much help beyond the basics. Hope you get her fixed up soon,

I think his next plan of action is to remove both valve covers and inspect the wiring and see if he can tell if an injector may be bad and letting the oil leak by. He also plans to get a gauge tomorrow and check the oil pressure while cranking to see if it is near 500 psi like it is supposed to be.

I dunno what it's supposed to be, but Gators truck, even with all the ICP issues we're havin, is peakin around 14-1500 psi ICP while cranking. So I'd think 500 might cause a long or no start condition? No expert, but with what we've eliminated on Gators truck, I think your buddy's probably got an injector goin down. His symptoms are worse than Gators, but along the same lines.

Was there any oil in the top of his ICP sensor? I think a bad ICP sensor can cause a no start.

I would hook up a gauge to read oil pressure while cranking (Low pressure side). With no oil in the HPOP, you might have lost the LPOP.

I don't think the ICP will cause a no start.

Check your battery voltage as well while cranking. Must be over 11.8v to start
