Suspect HPOP

Driving down the freeway truck lost all power. When I came to a stop, it died and now will not start. Turns over but doesn't fire. Using the EDGE CTS, ICP never goes above .5 during cranking. I have an AutoEnginuity I'll be using to further troubleshoot in the morning now that the truck is in garage. What all should I look for?

Thanks in advance.

It's a late model 04 BTW.

Read thru the no start sticky for the diffeent tests and how to do them. It lists just about every problem that can come up on a 6.0. The link is the one just before the link to this page at the top of the Forum.

Thanks. Went through most of that thread.

Prior to doing anything I ran a KOEO Self-Test. Came back successful.
Also performed a KOEO Injector Buzz Test. Came back successful.

Going through the thread here is what I found:

FICM - 47.5-48VDC - GOOD

Batteries - 11.63VDC - Both are less than a month old.

Low Oil Pressure - Dash Gauge registers oil pressure after 4-5 seconds of cranking.

High Pressure Oil only gets to mid-400 PSI during cranking with the IPR at 84.77%.

Changed the oil just to be sure all is well. Same issue.

I had planned on removing the heads to have them gone through as I suspect a bad head-gasket. While its apart should I just replace the HPOP and IPR valve along will new o-rings on the HPO system?

Or could there be another issue that wouldn't be fixed with all that?

ICP sensor was replaced last summer and appears to functioning since I am getting accurate readings with the AE and the CTS.

Thanks again.

I just ordered some fittings and adapters so I can pressure test the HPO system before pulling the trigger on a new HPOP.

Can I use the AE to close the IPR for test or do I NEED to apply voltage directly to it?

not sure about AE but you can apply 12v to the IPR to close it. Actually all you need to do is ground the wire from the IPR to the PCM with the key on.

You should hear an air leak from the back of the engine with the IPR open and it should audibly seal up when its closed. Pull the oil fill cap to listen to the right side, pull the air duct/ccv hose for the left side, and pull the oil filter cap to listen for an internal leak from the hpop. No change in the noise may be a faulty IPR

Finally tested this. With the turbo removed and 100PSI of air supplied to the oil system via ICP sensor port I hear pretty much all air escaping the turbo oil drain tube. The sound changes slightly when I apply voltage to the IPR valve but it doesn't "seal up".

Here's a video.


Thoughts?

Should there be NO air leaking from anywhere if the system is good?

I pulled the IPR valve and found a bad o-ring.

I replaced the o-ring and retested. The air is nowhere near as bad but still there and now the change when applying voltage to IPR valve is drastic.

Could that o-ring have been by problem?

Yes, that could be the only problem.

Depending how you applied power, you may not get it to close completely. AE has a bug closing the valve fully, depending on the value you select. If you ground the striped wire, that should close the valve. If you apply 12v+, you still need to ground the other wire. If you still hear air, you may have another leak.

What is the ICP now when cranking?

I haven't tried cranking it. Since the turbo is removed, it'll spray oil out the oil feed.

I used a pigtail and applied 12 volts directly to the IPR with opposite lead on negative of the Battery. I noticed the AE will only allow the IPR to go to 84%.
