6.0L Power Stroke Engine and DrivetrainDiscussion of the 6.0L Power Stroke diesel engine and drivetrain in the 2003-Up Super Duties and Excursions. No gas engine discussion allowed except on transmissions and drivetrain that pertain to all models. Please confine discussion of topics in this forum to those items that are specific to the 6.0L Power Stroke engine.
2005-6.0, F350, 133,000 miles on engine. Was heading to Austin yesterday, truck was on cruise control running 70mph going up a long grade overpass, the tranny dropped into passing gear and as I neared the top of the overpass I tapped the brakes to disengage the cruise, at that instant the engine went dead.
I have ran a FICM check and all the voltages are good, fuel is making it up to the secondary housing, (new filters a couple of months ago), all electrical systems seem to be working fine, no check engine light.
I know its a bad idea,just wanted to see if it was getting some air intake. Did a very quick check with starting fluid, engine will try and fire, it just seems like its getting no fuel whats so ever, it will not fire when cranking. I can hear the fuel pump running with the key on.
Any ideas? it just seems odd that it died instantly when the cruise disengaged, thanks for any help.
Need to run a test for codes. Common to lose high pressure oil to injectors on a stock motor. A P2290 or P2291 would confirm that. There are a number of upgrade parts from Ford that make the 6.0 much more reliable.

Interesting. Did you check any fuses? And you say you can hear the fuel pump running with the key on. Shouldn't it go off after a short time?

I did a cursory check of fuses, will do one with more detail now, The fuel pump sounds as if it is pumping up to pressure then the noise goes down to a very slight humming noise. Any idea of which fuses to check? Is there an easy way to check the hpop. And last, where can I get a code checking device? Thank you.
My SCT tuner is what gave me the low HPO code that came from a blown STC fitting. I know most cheaper OBII readers will not pick up all the codes. I personally don't know much about code readers or which ones to buy so hopefully others will chime in with more information. Only thing I can suggest is, getting the truck to a dealer, so they can plug in and run their diagnostic equipment.

I would suggest reading the IPR value. You need at least 500psi for the PCM to okay firing the injectors. You have the STC fitting prone to failure, so that's a concern, but pretty easy to fix if that's the culprit. You may also have an HPO leak from a blow d-ring on a standpipe or dummy plug, or an injector oil rail o-ring. You can air test the system (but you must command ICP closed or hot wire it momentarily to check properly). I'd suspect the STC first, and just replace that in the event that IRP is not where it should be. If that dosen't cure it the leak is somewhere that you won't be doing double work to get to it, and that fitting is a time bomb anyway. Also look at the IRP screen and check for damage, as bad IPRs are not uncommon. With that kind of mileage the HPO screen should really be replaced, which is a PITA is you aren't doing an oil cooler at the same time. A frequent cause of IPR screen damage is junk getting into the HPOP from a bad screen.
Another thing to check is the ICP. It's on the front of the right valvecover. Unplug it and see if the engine will fire. If it does the ICP is bad, just replace it and rock on.

Another thought, when you disengage the cruise control it cuts fuel, which is why sometimes it can be an abrupt, rough disengagement. I'm not saying it explains anything, just something to have in your knowledge bank.

I am betting that it does have something to do with the cruise control, the instant it was disengaged the engine went dead, I checked all of the fuses,none bad, so I had no option but to tow it to the dealer today, $150 to check it out, I hope its a cheap fix...lol(sarcastic laugh)

Got it fixed, Iwas forced to take it to a dealer, it was the valve (IPR?)right before the HPOP and two blown dummy plugs. Had it all replaced along with the screen on the valve. total cost was 1785.45 I want to thank everyone here for thier help, you guys know what your talking about.
Where are those dummy plugs. I am experiencing the same problem with mine. Turned off the cruise control and the truck shut down. Already replaced the ipr now wondering about those dummy plugs. Thanks

I had the exact same thing happen when a seal on the top of one of the injectors spit out. The HP pump was handling it at revs but when I topped a hill and the cruise cut back the throttle and engine speed fell it shut down and never made enough injection pressure until it was towed and fixed (it was still in warranty).
There a few places where HP oil system could pop a seal and there is the STC fitting if not already replaced.
