Ok lets start off by saying thanks to all for the
feed back. I have a 96 f350 7.3 crew with
350,000ish on the clock i bought the truck
about a year ago and the truck ran good. This
is my first time owning a diesel and know
nothing about diesels so i had to learn. one
day i hopped on the freeway started running
weird cel came on and by the time i got home
the light was gone. The truck would not start
after that. Fast forward to a month ago ive
replaced the ipr,icp,cas,fuelpump(all
motorcraft),hpop (cnc stage 1) with my snap
on solus scanner hooked i was getting 200ish
icp. I can jump the ipr with 12v and the truck
will start so i know its not fuel related. Fast
foward to present i bought a used dpc-202
thinking the pcm wasn't controlling the ipr
plug it in and it started and ran 5-550 ipc and
around 15% ipr for about 10 min then got
worse and worse and died now on the scanner
im getting 3500 icp and 95% ipr. I swapped
pcm back to the original and its back to 200
Icp. The video was to big to post so i had to take pics of it. As soon as it hits 500 psi it tries to start but it just stumbles. The last pic is key off

 

Sounds like low oil or injector leaking at the base

The other PCM tried to keep up pressure as it was leaking by

Could be loose IPR or oring on it tore up, there is a screen on older ones that can clog

 

Injector seals are my next move
