How much cranking have you done? Are you reading hpo pressure? Maybe I missed it. Since you had the system open multiple times you have a ton of air in the system. When I went through this after a blown hpo line and swapping them I had a ton of codes. I paid no attention to them at all. It took a very uncomfortable amount of cranking to get my truck to restart. I ended up hooking up 2 cars to my truck to keep the batteries charged because my chargers were not supplying enough power fast enough (I'm impatient).
All of my codes went away once it fired by the way. I do remember them having some relevance to what was going on and some not so much.

Im going to do that just to verify that the injectors are seated properly. Im trying to find a pcm or idm I could borrow as well. If those don't do it I'll keep going

Check for 5v reference and let us know what you have, if it tests within specification, then we can recommend another step. If it doesn't test within spec, we can recommend a corrective action.

Please look at what I said about P1670 above, it can be a ghost at times...

Your injectors may or may not be seated properly. The DTC's you are seeing and have repeatedly posted are not related to unseated injectors.

A spare PCM/IDM might be a good idea, but make damn sure it is known to be a working and well functioning PCM/IDM. Do not buy a store brand PCM/IDM, we have seen so many of those bad right out of the box it is ridiculous. I can recommend some places to get an IDM if that is what you need, but PCM/IDM repair should go to Jonathan at Diesel Tech Chattanooga, which I linked above.

Keep going, but address the questions these fellas ask. Don't skip over them or leave them unanswered because they are asking them for a reason. We have been known to fix some crazy issues, but we need you to be the eyes, ears and hands on the scene.

We look forward to an update from you soon!

Peter may be onto something here. Easy to check too; pull both connectors off and see if it starts. Truck will run with IPR disconnected.

Truck will NOT start and run with IPR disconnected. The truck WILL start and run with the ICP disconnected. Easy to get them mixed up because of the acronym and their location.

Thanks for the correction Sous! Peter and I both spaced on the acronym.

Can still be the problem tho, ICP and EBP connectors switched.

No worries sir and I agree, this could be a big problem and it is easy to check.

They are 100% not mixed up. I pulled the old connector off the ipr and was frayed to bare wire by the connector so I immediately replaced it. I know that its the right connector. The truck was started and running before it shut down suddenly after running for 20 minutes, it never would have started if it was swapped

I have an extra pedestal from an OBS I decided to take apart just to understand how it worked, and it is basically controlled with an IPR valve.
