All you do by unplugging the ICP sensor is cause the PCM to use a default value. It only helps when the ICP sensor is bad. Looks like your low ICP pressure is real.
If you have no leaks, it would have to be one of 3 possibilities:
- starving the HPOP by not feeding it sufficient oil
- bad IPR
- bad HPOP
If your HPOP is not getting enough oil to it, it could be:
- aftermarket oil filter cap with an OEM filter
- leaking oil filter housing drain valve
- stuck LPOP regulator
- bad LPOP
Does your oil pressure gauge on the dash come up when you crank for 4-5 seconds?
Remove the oil filter and crank by jumping the starter solenoid with the key off. How long does the oil filter housing take to fill up?
Since you removed the IPR, have you inspected it closely (internally) to see if anything was stuck inside of it?
What did the screen on it look like?
Did you clean it?

Two things -
Replacing parts without testing can get expensive.
Installing aftermarket (non-OEM) parts can also get very expensive since they fail so frequently.

I am a big diesel tech Ron fan it’s a shame he’s gone I didn’t take the screen off the I PR because it looked perfect and I assume if I take it off I have to replace it which is an a big deal it’s only $35 for the kit but are you telling me to take it off and see if the plunger works

Start with doing/answering this:
Find the yellow with light blue striped colored wire which is adjacent to the passenger side battery in the engine compartment, it is near the vacuum pump. It has a "squeeze-and-pull" type connection. Disconnect it, and jump the male end of the connector to the passenger side battery positive terminal. The starter should crank. Leave the key in the off position to just crank.
