03 6.0 wire chafing?

my truck died while driving a few weeks ago. it was throwing code P2623 and low oil pressure while cranking. i thought it was a bad IPR so i replaced the IPR and ICP, and also installed an EGR delete kit. i checked out the HPOP and HPO lines and did the air pressure test, no leaks there.

once everything was back together the truck started up fine and ran good for a few miles. on my way back from the test drive it suddenly had no power under throttle so i lifted off and got back in it and it died. put it in neutral, cranked it and it started back up.

got home shut it down plugged the scanner up and it was throwing codes P132b, P2614, P2617, and P2623. and now it is cranking but no start.

IPR while cranking 84%, injector oil pressure while cranking around 250psi. i have no idea where to go from here the only thing i think i could be is wire chafing. and that was probably the problem the whole time

any advise is greatly appreciated

There was no metal in the IPR screen, and my dad did the air test so i dont know exactly how it was done. I found the cause of the problem today though. The connector the IPR is making weak contact to the IPR. It would get loose and truck would die. as soon as i wiggle the connector or wires truck would fire right up. is there a pigtail i can get from ford for the IPR like you can for the ICP?

Now i have to address the lack of power in first gear. at WOT in first gear RPMs go up but no power, it sounds like the turbo isnt spooling up. i have to back out of it and let it shift to second then it'll pull however turbo spools up pretty slow. the turbo is clean i inspected it while it was off last week, and the veins were replaced in december. its thowing a P132b code and i dont know were to start to look for the cause of that
