Well then I guess the PCM is ok. I'd diagnose/work with this one, and put the original PCM back in when you're up and running. Your F5 is ready to roll with that PCM, dunno about the new one.
Have we gone down the fuel heater short/blown fuse path yet? Harness rubbing on DS valve cover? Getting WTS light like normal? Any codes come back?
Edit: trailer it to Andy's next weekend, we'll work on it there over a few beers.

I would pull the IDM, clean the connections, check the ground, then go back to your oil problem after the FIPW reads 0.6. Optimistic, eh?

Are there any other codes present, or is that the only one? Just to confirm, it's P1668 right?
If it's the only code, do you have anyone nearby who would let you put your IDM in their truck and see if it will start? If you can, and it does run, that would pretty much rule out the IDM itself as the problem. If it isn't the only code, there are a couple circuits that need to be checked for continuity and/or power.

Now we're talkin' IDM. You need the FIPW to say 0.6, and it only does that when IDM/PCM talk to each other. You have two PCMs not giving you the sync signal, and one PCM throwing an IDM code. I'm guessing that ROM error on the other PCM failed to allow the IDM code to show.

no start, had a CEL, pulled dtc's and got 2 glow plug codes and aih code and a few instrument cluster codes. Ran KOEO and thats when the p1668 came up.

If I were he kind of person to go "all-in", I'd push the stack on the 0.6 ms being there when cranking... but I'd better double-check Stinky with the just sittin' KOEO thing. I'd hate to think I put you on the Merry-Go-Round.
From that last link in my signature:
Pulse Width; 0 ms means no sync, 1994-1997 .42 ms indicates
that PCM and IDM are in sync (on 99-03 it should be .60 ms) and
the PCM is waiting on the ICP to reach the minimum of 500 PSI.
When min. ICP is reached PW should change to 1-6 ms

Aw crap. Look for the 0.6ms while cranking - not KOEO. Pikachu has it right and I'd try to come up with something humorous right now... but this ain't funny. I made you waste hours on this just before a holiday weekend, and you're trying to make a living. I do everything in my power to avoid this very thing from happening, but I allowed myself to be distracted with overload on my end. I sincerely apologize and regret the harm/stress I've caused your situation. I hope this gets resolved today, and I'll do what I can to make up for the wasted time. I owe you one big damn beer.

Getting back to basics... What could be causing me to 0.00 ICP?
Pulling the HPOP is not my idea of fun, I just had it off approx. 3 months ago for a rear o-ring leak. took it to Joey and he replaced the o-ring and bench tested the pump. Does the 0.00 ICP sound like pump failure, or are we still working with electrical and other probablities?

Could pull the access cover and make sure the gear is still attached to the pump. Or could get the fittings and rig up a mechanical gauge to check the ICP. I have read where others have done this, but I'm not sure what all you would need.

I know it would be messy, but did you inspect the hpop gear, and if it was tight, did you unhook one of the quick connects to see if oil shot out while cranking. Obviously a gauge wouldn't be as messy, but for a quick/cheap check.

The last ICP voltage reading you said you had was .22 volts, which works out to about 100 psi or so. That's about what I had when my IPR puked. I know you said it came off a running motor, but it's one possibility out of several.
