Based on your last few comments, it appears you do in fact need to purge the air out of the HPO system. While the batteries are charging, check the HPOP reservoir and make sure there is oil up to about 1/2" from the fill plug. If there isn't, put some fresh oil in there. Once the batteries are ready to try and start the engine, let us know what you see and hear.
If there is no engine light on, you are getting close and the issue is mechanical in nature and may just be too much air in the system.
Keep at it sir, you will be
in no time!

Well, you can either leave it and assume it is full until you NEED to check the level. Or, you can remove it at all costs and get a replacement sent out to you.

At this point, if I were you I would probably leave it be until I needed to verify there was oil in the reservoir. This does not solve the problem that your fill plug is in need of being replaced, but you can tackle that later.

that oil level should be fine. As your cranking note if the icp pressure is going up.
Go to tests in the app, and do a buzz test just to verify all the injectors are connected and able to fire

crap. wouldn’t start
pic below is when key turns on and pic below that is when cranking.
yes icp pressure was building. The first gage showed about 186 consistently and the second gage spiked to that level a few times.
gave it 3 or 4 runs of about 15 secs but battery’s need more charging.
I will do buzz test later when battery’s have chance to recharge

Keep trying to crank it a bit more, I would have thought the air would have moved out by now though. When I changed my HPOP lines a couple years ago, I don't remember having to do more than about 30 seconds of total cranking to purge enough air to start. You have a HPO problem somewhere as indicated by the ICP and IPR values.

I installed the high flow fuel fittings with intention to do larger flexible lines at some point. Don’t think that could be it. IPR readings seem ok? I thought maybe solenoid? Something I forgot to do with Oil Cooler, or with that plunger in the fuel bowl? Or maybe something just pooched coincidently during the maintenance? (Unlikely). I tried disconnecting the icp sensor and they say it should start if that’s the issue.
Something with the valve cover gaskets? Think I connected each glow plug.
but there is little to no exhaust when cranking. Does that mean fuel not getting there? No engine light now means it’s not an Electrical/sensor issue?

No, they do not seem OK... IPR should NOT be 65% when trying to start the engine. It should be no more than 20% when trying to start the engine.
Not likely... This is a very simple part of the truck and it will let you know if you did it wrong.
Maybe, but your readings indicate a HPO (high pressure oil) issue. 500 ICP is minimum for starting and IPR should be near 20%. If you unplugged the ICP, it will default to 725 by the PCM, so the problem is NOT likely the ICP sensor itself.
Your immediate no start issue is NOT a gasket problem.
Your truck not starting might be a GP issue, but the HPO clues based on the readings is where your bloodhound should be sniffing.
Typically yes...
Do you hear the fuel pump come on when you turn the key to on? Open the drain valved on the back of the fuel bowl after turning the key to on and see if fuel comes spraying out.

I would ohm the ipr solenoid off of the truck.
based on my findings when i had mine assembled wrong it resembled a bad solenoid. Im guessing that.
looks back at my screenshot, same ipr percentage and basically same icp.

Sounds good.

You are probably right...
answers below.

ok. Strange, IPR was reading 14% and change when 42 pin was not plugged in. IPR should close when starting and open to relieve pressure when running. I guess only way to confirm proper operation is install “known functioning IPR”. Or eliminate other things

ok I will try disconnect the sensor and try again just to see what kind of pressure is being generated without it. But unlikely as it didn’t start when I tried before I had forscan and had old harness hooked up.
Your right, it is unlikely. Seeing as how the 42 pin connector was not reconnected at one point, you should retrace your steps and look for anything obvious. Did you rebuild the IPR or anything else associated with the HPO other than the HPOP lines?
yes rebuilt the IPR and checked it again a few days ago All seemed ok. Orings in place, clean, etc. Pics above. Don’t think I can check solenoid?
did fuel lines. Fuel bowl. Nothing else with hpop Turbo seals. Pedestal seals. Ebpv rebuild
Your immediate no start issue is NOT a gasket problem.
was thinking the injector seals are leaking preventing pressure build but was starting before maintenance. So shouldn’t be enough to prevent pressure build
Your truck not starting might be a GP issue, but the HPO clues based on the readings is where your bloodhound should be sniffing.
makes sense. Getting 186 and need 500plus
Typically yes...
Do you hear the fuel pump come on when you turn the key to on? Open the drain valved on the back of the fuel bowl after turning the key to on and see if fuel comes spraying out.
fuel bowl was full last I checked. But will hook up a line to the fuel bowl drain and see if there is pressure. With key on. I get a buzzing with key, a click and everything sounds like usual, best I can remember
