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?

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.
