  1. Diesel Diagnostics
    Went to start my truck this morning. Sitting all night in -6° C. So it’s not that cold but I guess enough to throw the truck off. Starts fine in warm weather. But this morning wouldn’t start at all. Turns over and would randomly get a fire but it would either last a second of running and turn...
  2. 6.0L Performance Parts Discussion
    2005 Ford f250 6.0L Truck will not fire off. I lose communication to the PCM and the FICM. The truck fires and then dies right away, maybe runs for maybe 2 seconds if we get lucky. I get connection back to both, and then randomly it just goes away. The PCM and FICM were both just replaced. I...
  3. Diesel Diagnostics
    No need to laugh, but I just purchased an 03 F250 6.0. This is the 1st vehicle I’ve ever owned with OBD2, so while I know my way around an engine bay, I’m new to all of this, this is my 1st diesel, and am looking for some help. I purchased the truck with blown head gaskets. I replaced the head...

    Howdy all! So I'm almost finished with my cab-off engine swap. Got the cab lowered Sunday after church, and most everything put back together today. Not sure where to start describing this issue, but here goes... The truck started after a good deal of cranking to prime the HPO system. It runs...
  5. 6.0 Motor problems
    I have an 06 Powerstroke 6.0, 125k miles. Replaced FICM 2 years ago. Died on me on the highway, no start. Only code I got was a ICP low code. Replaced the ICP, still no go. So I'm thinking I need to replace the dummy plugs/stand pipes and possibly the IPR valve. Ordered an IPR valve today and...

It has head studs, EGR delete, 4 inch straight pipe, AEM Intake, and an Edge performance system and 58v ficm. Recently I did head gaskets on this truck and before starting...
  7. 6.0 Motor problems
    Hi, I have a question about my truck(03 F350). No start issue. when I disconnect the FICM, the high pressure can go to 800 or 1000 PSI when cracking. but when I plug FICM in, now matter how I crank, I can only get ~400psi. hence now start. The FICM voltage is good at 48.5 and FICM sync is 1...
  8. 6.0 Motor problems
    OK I don't think I'll get a reply but at lease I can vent.Have a 07 6.0l no start. I have 53.0 FICM, Sync,IRP will reach well over 500psi, even over 1000 psi, IPR at 85% but will get back down to 60% or so and try to start. Batters very good and hot. Placed a rest fitting and gauge at the IPR...
  9. 6.0 Motor problems
    I keep getting a cylinder 5 contribution/balance code that will come right back as soon as I clear it. But if I turn the truck off, clear the code, and turn it right back on it won't come back for the rest of the drive. The idle is a little rough when I have the code but not too bad and runs...
  10. General 6.0L Discussion
    I am aware this has been discussed many times before, however money is tight and I cannot afford to throw parts at the truck at the moment. The motor has Studs, CAI, Alliant 155/30 injectors which are 1 year old, Coolant bypass kit, EGR is deleted, Blue spring mod, 4" turbo back with a muffler...

    Changed my oil this weekend and within 100 miles of driving my check engine light came on. Thought maybe it had to do with the oil change, but when I checked the codes (P0261, P0264, P0267, P0270, P0273, P0276, P0279, P0282) it was a low circuit on all 8 cylinders. The truck is running EXACTLY...
  12. 6.0L Problems Forum
    So my dad was driving the 6.0 and he said as he was driving all the lights dimmed, the gauges all dropped, and then the engine died. When he went back out to tow it home it started right up and he was able to drive it home. I replaced the ficm's power board and the alternator about 2 months ago...

    New Here, working out a no start issue and will be grateful for any help I can get. Truck started missing and ran like crap coming home one night. on that drive it kept losing power, but if I put my foot on it I could "blow it out" and carry on. Limped home. When I got home I shut it down and...
  14. 6.0 Motor problems
    I have found lots of posts chasing around various issues with Loss of Power & Rough Idle. I have read all I can find hoping for an answer but as of yet I have found none, with the possible exception of either 2 bad injectors or a shorting Fuel Injector Harness. My Story: 2003 Excursion with a...
  15. 6.0 Motor problems
    I have a 03 F250 6.0 with 230,000 miles. I don't seem to currently have engine problems that I know of, but my Edge Insight monitor was reading wacky FICM voltages. Right after start, the voltage was dropping to 34.5 and eventually as the engine warmed the voltage was back up to 48V +/- .5V...
  16. 6.0 Motor problems
    I have an 05 6.0 that originally had Cylinder 8 Injector Circuit Low (P0282), I checked the Injector 8 wiring on the injector harness and it was spliced by the previous owner so I respliced it with a heat shrink connector. That fixed the loss power, and then ran like normal. Then, the next day...

    Torque Pro question.... Is there any reason that my FICM would be reading so low and not reading EOT at all? 6.0 deleted, runs great, no issues. Not sure if this has anything to do with it, but since the last time I ran the Torque Pro app, I've changed my ICP sensor and had a short in my guage...

  20. 6.0 Motor problems
    So about month ago my 03 6.0 powerstroke up and died in the middle of an intersection on me and had to be towed home. It had been having really low RPMs all day, got home changed the fuel filters and oil. Took the tuner off and it threw up a FICM code, so we changed that. Just had Ford...
