WTS light coming on? CEL illuminated? Fuel Pressure? Fuses good? It's probably just me, but I don't like to do multiple mods at one time. I would have installed one of those (injectors or Hydra) first, got it to run then move to the next. Cheers!

Remove the chip.

The HPO system has air in it, so it will take a lot of cranking to get the air to to the point that the injectors will fire. Most remove the glow plugs to make it easier on the starter/batteries while trying to purge the air from the HPO system. If you don't remove the glow plugs be prepared to crank for a long time before it fires. Not uncommon to drain battery capacity before purging the air.

I took the chip off and I've been cranking it on and off for close to 3 hours my batteries are on life support at this point

I did find my scanner though and pulled some codes and got P0603, P1212
I ran a buzz test for giggles and got P1271, P1273, P1293, P1294, P0001, P007C

Start with clearing the codes. Is the HPOP still full? I've never had that much of a problem getting it restarted after R&R'ing injectors. I do crank it with GP's out as Greenskeeper mentioned. When I replaced my Oil Rail End plug, I refilled the rail prior to cranking by removing the forward-most port plug (small ports where HPOP hoses attach) and using a small funnel to fill it (letting any air make its way out). The truck fired right up without even a hiccup. Cheers!

I would do the ICP and the corresponding one on the passenger side. Those are the "highest" ones, so air should go towards them. Cheers!

seems like a harness isn't completely plugged in?

No need to attempt to fill the oil rails, the HPOP is doing that since it's full as you stated.

I would pull one (or both) of the valve covers and see if oil is coming from the injector spouts while cranking...that would prove the HPO system has been purged of air.

if you pull the covers, have a buddy crank it and observe around the injector body where its bolted down. if you see oil coming out around it youve jacked an o ring up possibly. i dont believe this is common...but it happened to me. i cranked for 3 days lol found all my pressure was going everywhere it shouldnt
