  1. 6.0L Surging & Revving at Idle

    General 6.0L Discussion
    I need input on an issue with my 2004 6.0L. It is making an odd revving sound when returning to idle. This issue us accompanied by a surging/loss of power. the IPR during these times is in the mid-30% range while the ICP is around 600-800psi. I do not notice any smoke when this is happening...
  2. IPR Screen and Oil/Coolant Issues

    General 6.0L Discussion
    Hello, My name is Walter, I recently bought a 2006 Ford F-250 Diesel with a 6.0 engine. First, I brought the truck in to a shop for an oil change and to have the check engine light diagnosed. In the process of diagnosing, the truck stopped running. It would not start because there was not...

  4. ICP Rapid Flux with Steady IPR%

    94-98 7.3L Problem Forum
    Experienced Diagnoticians, My 97 7.3 with 225k miles has started to idle roughly and run roughly until fully warmed up and, then sometimes even after its warmed up. No surprise, its winter time. It is particularly noticable when engine is still cold and going up a hill. Sometimes it will even...
  5. Seemingly extremely complex!

    6.0L Problems Forum
    Right to the point then I'll paint the picture. 2007 F250 No injector clatter BUT does start then runs really really rough KOEO all sensors perfect except icp, voltage is .33 check, and icp is 90psi?? Once it starts icp shoots to 3400 and ipr to 55ish runs like crap can't find idle eventually...
  6. CEL on hard acceleration - IPR?

    99-03 7.3L Powerstroke Problems
    I've got an '03 7.3 with ~230k miles. I had oil leaking out of the HPOP so last week I finally got around to resealing it as well as the fuel bowl. changed the oil, put it all back together, started up fine. Drives fine. But I get the CEL to kick on any time i'm pushing it and im accelerating...
  7. 6.0 Bad IPR?

    6.0L Problems Forum
    So Ive got a 2003 6.0 PSD. It wouldn't crank but unplugging the fan clutch solved that, now it will just crank. The ICP has oil everywhere so i unplugged it. I plan to change it out soon. That didn't change anything. Good fuses, good ficm, good starter and solenoid. Im out of options I could...

    General 6.0L Discussion
    been searching the threads; can't find an answer. 2007 F250 6.0L with 138k on the ODO. was starting to take longer and longer to kickover, so I benched it and began working on the engine. Found one of the dummy plugs to have an O-ring that was starting to fail. Figured while I was in there...

  15. 05 6.0 no start after replacing IPR, 169000 miles

    6.0 Motor problems
    Truck was running normal then died as if it ran out of fuel. Plenty of fuel in the tank. Pulled codes and codes were: P2290; P0528; UI900. P2290 is Injector Control Pressure Too Low. Read up on P2290 and suggestion was to check that low oil pressure would build on a long crank. Low oil...
  16. Attending to intermittent no-throttle-response and some miscellany

    General 6.0L Discussion
    I was going to stick this in the "What did you do to your 6.0 today" thread but it seemed too involved for that. I am posting it because the no-throttle-response is a problem that - in particular - seems to have a mish-mash of less-than-helpful information on the interwebs. ___ So... I have...
