    1997 7.3 F250 with a crank no start. Truck sat for about a year. New ICP, IPR, and CPS Currently no codes when I try to read them with FORscan, but batteries were replaced so maybe that is why. I plugged in FORscan and watched the ICP, IPR, and CPS signals live (see photo) I get flat lines for...

    2006 F250. P2285 code just came up. Truck has recently had new injectors(155/30), standpipes, dummy plugs, oil cooler, icp sensor and pigtail, and ipr and pigtail. The truck runs pretty good other than when coasting when the truck was in overdrive, the engine will miss until the speed comes down...

    Ok, I have a 2004 F-250 Super Duty 6.0L. What is the socket size needed for the original IPC? I keep seeing 24mm and the new IPC is. But 24mm is not going around the original.

  5. 6.0L Problems Forum
    Hey guys, I have had my 05 6.0 for a couple years now and the last year I’ve been tracing down this really odd issue that no one seems to be able to figure out. The issue all started with me replacing my injectors and ficm. I did all the work myself and know for a fact that everything mechanical...

  8. 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...

  10. 94-98 7.3L Problem Forum
    I want to be thorough to get the best help I can, so this post is lengthy. Over Xmas 2019 I was given a ts chip and decided to try it out. However In February I began to have idle issues on colder days. The truck would start with no problem but a few blocks down the road it would quit and Id...

  12. 6.0L Problems Forum
    Hey there! So I have a 2003 F250 that hasn't been running smoothly lately. The main issue is when I'm idling, usually in drive but occasionally while parked too, the truck seems to miss/stumble a little bit. It'll sorta bog down into the lower RPMs and act like it wants to die. So the RPMs seem...
  13. 99-03 7.3 Motor Problems
    Hi All! Been reading great stuff on this site for years. First time i speak up! Stranded after driving my 99 7.3 8 hours. I ran low on fuel pressure all of a sudden. Got towed to a Hotel. I have Wife and 3 kids with me and it's around 0 to 15 during the day. i Replaced the IPR to get pressure...
  14. 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...
  15. 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...
  16. 94-98 7.3 Motor Problems
    I had a leaking ICP that lead me to clean and reseal the fuel filter housing ( tablespoons of crap in the bottom of the bowl) replace the rubber fuel lines, prefilter and reseal the HPOP as a preemptive maintenance along with replacing the ICP o-ring. The ICP wasn't even hand tight when I found...
  17. 6.0 Motor problems
    My 2007 6.0 acted like it's running out of gas. Then ides fine. You can get it through the sputtering and nail it and it runs fine at higher idle speeds. Finally it would not start. I changed the ICP sensor and it started and ran fine for 30 minutes of driving. It was a cheap icp...so I bought a...
  18. 99-03 7.3L Powerstroke Problems
    I haven't posted in a while as my truck has been purring like a kitten. In fact, it was purring like a kitten at 75mph down the highway the other day (and I said, man, this thing is running GREAT!), seconds later, it coughed, sputtered, then ran again, then coughed, sputtered, ran, then died as...
  19. 6.0 Motor problems
    I have a 2005 6.0. It will crank up just fine even in cold temperatures. It will idle fine for about 5 minutes then die and not restart. As it idles the ICP will start at 1300 to 1400 and gradually it will drop to low 500's then it will die. It does not drop below the low 500's before it dies...

    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...
