Grasping at Straws....What Do I Try Next?
Good strong crank...I put the charger on the batteries, so no issues there.
I just took it apart to verify just that and all HPOP O-rings, stand pipe O-rings, and log style oil rail seals are good (or at least I don't hear/see any leaks from them).
I would also make sure the IPR isn't preventing the truck from starting. I had this problem on a 2006 F350. They said they took it to get inspected and it wouldn't restart after, wouldn't restart cold either. We check the ICP while cranking and it shows all the familiar signs of dummy plugs. We replaced the dummy plugs and standpipes and the pressure got higher at 350 psi, but still no start. The IPR was replaced and it fired right up no questions asked.
I would also use shop air and make sure one of the top injector seals aren't leaking. One of mine are and my '05 will start run and drive, but not long after it's fully warmed up, it stalls and will only restart cold. I have the revised STC fitting and standpipes, but did the HPO rail nipple cups a little under 3 years ago. Just something else to consider.

I replaced the IPR and IPC while it was apart and used shop air to test the injector O-rings. With the HPOP out I put shop air directly into the branch tubes, I don't see or hear any leaks from the O-rings.
All good ideas...it's definitely not building pressure. The gauge only shows that I build 200 psi while cranking.
I replaced the stock HPOP with the Dieselite unit and I added oil three different times to prime the HPOP and when I pulled it out to verify that the O-rings were in place correctly, the HPOP was full of oil, so I'm pretty sure that it is pumping OK.
The dash gauge is the only one I have for the LPOP and it is reading closer to the "H" than is it to the "L". Again, I'm pretty sure it's OK since it shows pressure and I get oil in the oil filter housing and I see oil at the HPOP
I get fuel at the fuel bowel.
I hear all of the injectors flutter at key on while I wait for the glow plugs to heat up.
I'm starting to think that I must have missed something obvious or there's something strange going on.
I know there's a ton of threads here, but I'm just not able to find the answer...I'm at a loss for what to do next.

I couldn't work on it last night, so I was planning to pull the wire harness and check the pigtail again. That is if the weather settles tonight, right now it's raining cats and dogs around here.

When she was running good I actually had that one plugged so that the oil could not pass and was forced through the oil cooler bypass at all times. When I put the new HPOP in I took the plug out. I will plug it again and see what happens.

At this point a gauge would give you true readings. That is if it's not also
got issues. The guys over at >>> https://www.hhcdiesel.com
do shave some test tools that might be handy.
The diagnostic deadhead plugs at this point are needed I think.
