chasing hpop issue

so long story short. one of our shop trucks dies on the side of the road. so knowing that its an 06. i figured stc fitting. it would only build about 25psi of oil pressure. i got a new hpop(not a bad idea seeing it has 218k on it) from international and of course it came with the updated fitting. and it wont build more then 70 psi? what else could it be? the ipr screen did have a big hole in it. i put a new screen kit on it.

The hole in the screen let in some dirt and destroyed the IPR. New screen wouldn't matter if the actual IPR is shot.

my issue is similar in that my screen was completely torn but what i thought was the main cause was d-plugs (they had chunks of the o-ring missing) so i replaced those along with standpipes and used a victor reinz master o-ring kist to replace injector orings and several others throughout the motor. hpop already had updated fitting. icp is reading 0 PSI ipr is 84% and ficm V is 48.5v, any suggestions guys?

Are you getting low oil pressure....dash gauge moving after cranking for a few seconds or the oil filter housing filling up?

Even with a bad IPR, my ICP reading was around 100PSI. Can you get shop air to it and listen for the leak?

yes i made a fitting to quick connect shop air at the icp hole and made a harness to apply 12v to the ipr which im going to run the test in the morning and im assuming if theres no change in sound of the air then the ipr is not working and if theres no sound when the ipr is closed and i hear no leaks then what? bad hpop?

so i did the air test and applied 12V to ipr and there was absolutely no change in the air leaking into the crankcase below the pump. went to ford bought a new ipr. got them to give me a courtesy discount and walked outta there only $230 lighter. i have some errands to do then i will be putting the new ipr in and air testing once more to be sure theres no leaks. does anyone know if it matters which wire gets B+ and which is ground??? i tried the old ipr both ways with no change but id rather not risk burning the new one up.
