My apologies to everyone, and especially BigJohn. Once again, I've found the enemy, and it is me. When I replaced the ICP sensor, I didn't reconnect the glow plug control module. Plugged them in and it starts right up. So sorry for distracting y'all from BigJohn's real problem.

I've done some rooting around and I believe that the oil is draining down back into the pan.
Does anybody have any ideas where I should look? Are there seals in the oil cooler that need to be replaced, how about the stand pipe for the HPOP?
Any comments or advice would be appreciated, also if I do have to go all the way down to the oil cooler again (EGR DELETE last time) are there other things that should be done while I've got the top open?

Thanks,

If it ain't broke, use a bigger hammer...

If it eventually starts, and runs fine, then I would rule out the HPOP. It sounds like a FICM problem. FICM power needs to be 48VDC. If you don't have a Scan Gauge to monitor the voltage then you have to remove the little plate on the FICM and check the voltage there. A real PITA. If you have close to 100K miles on the clock, suggest you go to your dealer and get a FICM power relay. About $40. It is a 75 amp relay located under the hood on the driver fender well. It is the box lid with the raised square on it. The relay is also colored gray and not black like the standard 30 amp relays.
