06 6.0 doesn't start suddenly
Gentleman,
06 F250 Stroker here. I've had no symptoms or any issues, maybe other than a little white smoke on startup. I last drove the truck on Saturday evening and everything was good. This evening I go to crank it, let the glow plug indicator cycle off and turned the key. The starter engaged with no response from the engine. I tried a couple more times and still nothing. There are no codes at all, IPR was up in the 50s and FICM was in good range while cranking. What could this be??

I will give the icp a check in the morning and report back. Filter cap is OEM. As far as the fuel pump, I didn't listen for it, what does it sound like?...I know on previous cars I have had, its like a buzzing noise. Where is it located? I can possibly try to get close to it to try to hear it.

Well so I went out this morning to check those statistics. In the process the truck started right up! I drove it around, it drove fine like it did the last time I drove it. The ICP at idle was about 580 - 595. What could have possibly caused the "temporary" no start issue? When I returned from the drive around it started up again just fine.

No, it was "cold". Coolant temp was around 70 degrees. I had driven it saturday evening and was trying to start it last night. This morning (still cold) started right on up.
Reminds me of the "Bill Gates syndrome" on my computer. One day Windows wont even boot, next day, Windows boots just fine, haha...I digress.

It's really important to get that ICP pressure gauge working. When it doesn't start next time, and it will happen again, check that pressure. You need 500 PSI before the PCM will turn on the injectors.
Leaks in the HPO system can come and go. The problem is temperature sensitive, but that is not the only issue. O-ring seals squirm around in the seat more than you might think under the high pressures seen in this system. This results in erosion of the seals. I've seen them with big grooves worn in them. But because they squirm around, sometimes they leak, next time they don't.

Yes, on the Scangage. The O-rings are those on the HPO system, primarily the STC fitting, standpipes, and dummy plugs. Injector O-rings can leak too. But not as common.

In a no-start, yes. In a delayed start, maybe not. The IPR should be closed while it is trying to build pressure during cranking.

This problem cropped up again after the truck was cold, sat for about 48 hours. I tried to crank it, and it would not turn over. After some cycling on and off, it eventually started up. I was watching the SG II and noticed the ICP was not hitting 500, it was about 350 something. The truck started when it said that, but do you all think this is causing my intermittent problem?

So you've got a high pressure oil leak, OR a bad ICP sensor. Unfortunately, because it does it after sitting, it is almost certainly a leak.

you said OEM oil filter cap so its not going to be easy
I betting Dummey plugs or standpipes might as well get them both done at the same time
I think your ICP sensor is fine since it does build oil pressure and eventully start a BAD ICP sensor would act diffrent it just wouldnt startt
