Default 2004 F350 Shut Off

Here I am again can't catch a break recently with this thing.

Truck is 04 F350 6.0 with build date before 9/03 and 147k miles on it. Just changed nipple cups, HP oil deals, stand pipes, and HPOP. Drove truck from NY to Georgia with no problems. Pull up to an intersection and just died on me. No codes. ICP pressure was up to 80-90 psi and no start. Unplugged icp and was seeing 1300-1400 psi and no start.

Any ideas? I have a spare icp sensor on hand and a IPR regulator as well.

That low of pressure sounds like an injector top seal blown out...

Is the icp sensor on the passenger valve cover or on the pump?

6.0 tech we changed the injector hp oil seals and snap rings think it went that quick?

No the icp sensor is on the HPOP cover

Its a possibility. If the snap ring wasnt fully seated or something like that, or could be a line had a seal fail in it. I would doubt its the pump with that low of miles, could be injectors pissing out the spill ports. Ive been seeing quite a few of those lately, especially on reman injectors. Had 2 different trucks a couple months ago that went thru 2 or 3 injectors each before one would seal up.

reason you see high icp with the icp sensor unplugged is because the pcm uses default values at with it unplugged. You have a major high pressure oil leak. Could always use ship air to figure it out

Could be the IPR sticking open or trash on the screen. I would pull the IPR and inspect. An 03 engine has fewer issues with leaks bad enough to cause it to just shut down, not to mention producing only 80-90 psi..

If that isn't it, then I wouldn't rule out a bad pump ..........

When pressurized with shop air and you can hear a leak coming out around the injectors and itís not the top seal, is that what youíre talking about?

Basically. If you look with a mirror, can see oil spraying out of the little holes next to where the hole is for the rail.

Ive really only had issues with reman early build injectors. Late build ones have been fine.

Right. So are you considering that a high pressure leak that can cause a no hot start? Iíve experienced that for sure and actually have an ambulance with a 6.0 in it at our shop now that I think has that happening.

Yeah, had one strand me on the road test after putting the injector in lol. Pulled it back in the shop, had to pull the valve covers when it was hot as fuk, and found the injector i had just installed doing that. Still had enough oil in it, it was making that side look smokey.

It is not common for an injector leak to leak so bad you can only get 80-90 psi but I will agree it can happen (anything CAN happen, especially if it was mis-installed, which doesn't seem to be the case w/ a drive from NY to Ga as a test drive).

OP - when you do the air test, also listen for a gurgle from the oil filter canister (as well as air leakage sounds from the oil fill tube and ccv hose).

So I checked on my truck yesterday and when I went to go try it for ****s and giggles it took right off. Built pressure quickly. Along the lines of the hp oil leak I did an air test after installing everything and she was air tight and i drove it around NY for 450 miles then decided she was back to normal so took it back to Georgia. I was on vacation seeing family and being in the air force moving and driving is what I do. I would think from what the one guy said about the possibility of **** clogging up the screen of the IPR as a reason and when it cooled off and got towed it knocked itself free?
my only consistent codes right now are P0528, P0603, P0670, U0306.
I had a 2285 and 2291 and I am assuming that was because I unplugged the ICP and tried starting it.

Thanks for all the help and I'm going to continue trying to diagonse this thing.

Btw I installed a dieselsite oil cooler, adrenaline pump, HHC diesel nipple cups, alliant injector HP oil seals and snap rings and a driven diesel regulated return. The air test after all was done held 120psi of air. Again thanks for all the info gentleman. Great talking with y'all.

Forgot to mention I tore into this thing because I was having hot hard start issues and I found the reason to be because a HP oil seal on top of number five injector was leaking badly. Could see air and oil coming out from under the nipple cup when we air tested it before tear down of the HP Oil system on it.

Check the GPCM and the PCM connections. Makes sure they are in tight and no wire chafing. Personally, I would still pull the IPR and look for screen damage and also closely inspect the wiring.

Right on I am going to try and do that. I am closing on my wife's and I's first house today and I start training tomorrow so maybe this weekend I'll get a chance to do that. Where are the GPCM and PCM connections?
It's just so wierd for it to do that after 1500 miles

PCM against drivers side - fender wall. Will need to remove the battery cover.

GPCM on passenger side of engine:

For a good pic of it:
Look on page 7 (but it is actually page 10 of the entire document):

Thanks for that. Checked those connections and I am picking up a scangauge2 to monitor ficm sync, IPR, and icp pressure. Truck wouldn't start yesterday and tomorrow I'm going to just put in my spare IPR to see if that helps it.

Check the IPR plug and wires at the plug. Try moving the wire harness to the IPR around then try staring the truck.

Tried moving them around but no change pressure was building to 360-460 psi. Will keep updated.

Changed IPR and still would not start. Wires all look good. Got a scangauge2 and ficm sync was one and IPR jumped right up to 84.7. I'm thinking that there might be leak in the oil system again. After just doing everything.

Messed with it some more and this time fuel light came on and I shook the truck and barely could hear fuel in it. Have been building up to 65 psi for fuel pressure.
New code popped up p2617.

P2614 and p2617 will set from extended cranking. Im gonna saay you got a leak. Youre gonna have to air test it, and find out where.

So for ****s and giggles this morning I put more diesel in it and it took right off. Had great oil pressure and fuel pressure and sounded strong. Got it up to 165 degrees oil temp turned it off and now I can't get Above 150 psi for oil pressure. Tonight and this weekend I am going to pressure test it to see if I can locate the leak. When we were pulling out the stand pipes the company who worked on it last just have cranked the passenger side down because it took way too much force to take it out. I'm thinking there's a possibility of the branch tube being messed up either cracked or something twisted too much. Will keep updated and thanks for all the advice.

Put air to it and I closed the IPR and I feel forceful air coming out the passenger side valve cover. Thinking stand pipe issue?

For some reason my kindle wont let me play half the you tube videos i click on, and yours happens to be one. Lol. Anyway, best way to pinpoint is with a stethoscope. Make sure the airflow changes slightly or you hear an electrical type click when you change the ipr, that tells you the ipr is working or not. If it is a large leak, it should be fairly easy to find with a stethoscope, just take the metal tip out, and find where the air is coming from. A small inspection mirror and a flashlight will also make things easier.

Good luck.

So when I activate the IPR the rate of air doesn't change. I'll have to pick up a stethoscope and small mirror. Do you do this from up top or from below?

So I dropped my truck off at the dealership because there's no diesel mechanics near me that I know of and last Thursday and everyday since it's been starting right up. Stopped by today and it was running when I got there and they are taking it for a test drive. Is it possible of an electrical issue? Something that shorts and then doesn't and then does kind of thing?

Leaks in the high pressure oil system aren't often intermittent unless it is oil temperature related (ie leaks hot and not cold).

I still believe you have something electrical going on.

One of your posts about the air sound not changing when you activate the IPR valve might indicate something if you are still occasionally seeing actual low ICP values.

the air doesnt change when activating the ipr so your thinking the ipr or hpop? i did put a new ipr in it and didnt help the issue. i also have a scangauge 2 and the ipr cycle goes straight to 84.7 during cranking

The 84.7 is just a command due to lower pressure than desired. Don't really know where the valve is actually. I am wondering about the wiring to the IPR. You should hear a change in air flow when it is commanded shut.

well after the test drive the truck would not start up again.
today they are starting on taking the cab off. they will find the problem this afternoon, tomorrow morning.
Just ordered the daystar Kevlar body bushing to swap out the 14 yr old body bushings on the truck as well.
Will let everyone know what we find out as we figure it out. Mechanic who works there owns a 6.0 as well so he seems decent with the engine.

Glad you found the issue, and thanks for posting it.

Question - where did you tie into for the air pressure test? I am still wondering why you couldn't hear a difference when commanding the IPR shut.

I was using the ICP port right behind the ipr. Only thing i can think of is that gasket was literally just letting all the air by even when the ipr was closed. Could have even been degrading the gasket more with air
