    So WOT ICP reading equals 1580 psi. That is pretty low. You need to inspect that updated fuel pressure regulator spring in there (look for abrasion wear and tear), but it looks like a fuel pump issue to me.

    Sounds like a bad HPOP and maybe an IPR problem as well.

    the boost problem was a rusted stiff unison ring.
    thanks for your help, i am currently doing some pressure tests to confirm it is the HPOP

    Just had my turbo cleaned up several weeks ago. Does make a difference.

    i also installed new hpop and that fixed the oil pressure problem and most everything but it has weird flutter or misfire under acceleration when cold. then just the other day it started running very rough and I figured it was some bad diesel that I put in from some old jerry cans but than the tranny started shifting weird so I really dont know what it is now

    Glad the HPOP has cleared up a lot of your issues. The flutter/misfire might be some injector stiction (oil related). Might try some Rev-X or Archoil. Usually when I hear flutter though, I think of the turbo. Can't recall - did you get yours cleaned up?
