    Have a DT466 non EGR which is demanding 3300PSI under load but won’t build more than 2500-2600. IPR % sits at 65.04% constant under load.

    New IPR, ICP, HPOP, injector seals, ECM, Engine harness.

    Truck starts fine hot/cold but while under full load spits and sputters and won’t build the pressure it needs. Pump has been bench tested, and the IPR is getting 12.3v. Grounds checked.

    Out of ideas if anybody has any suggestions. Thanks!

    Injectors themselves would be suspect at this point. Unplug all injectors and crank, check for leaks between injectors and the rail.

    Have you replaced the injection pressure sensor?
    What is the last 8 of the VIN?
