05 F250 Ran fine until, BAM No Start

I bought a 05 F250 back in November. Its needed Head gaskets since the day i bought it. I was gonna do them this summer but anyway, on to the current issue im having. The truck ran great minus the Head gasket issue up until monday of this week. I drove the truck to work monday afternoon. 10 hrs later, The truck wont start. It cranks and cranks but it wont even try to fire. I checked the FICM, its putting out 48v with the key on and while cranking.

I dont think its getting any fuel. Theres no smoke coming out the the exhaust, just air. Ambient temps have been between 35-55 when i tried starting it.

I think its related to the HPOP. Any other opinions?

Any idea what your icp is it should be over 500psi. If it still doesn't star try un plugging the icp and crank it this will thro the ipr int a default mode to start if your icp is not showing 500 or more.

You could put a gauge where the icp is if you have that. First try the icp unplugged if it won't start normally. It still could be a number of things wrong with it though crank sensor. So start with unplugging the icp and see if that helps then go from there.

ok the trucks still out at work it will be a couple days before ill be back out there. Ill give that a shot!

Im curious though,
I do have a SCT SF3 i was gonna use for the truck after i installed head studs. (was gonna do it in a few weeks, along with the SCT fitting, and a few other things haha
I plugged it in when this happened and pulled DTC codes, of which there werent any. Wouldnt there be a code if the crank sensor was Fubared?

Unplugged ICP, still just sits there and cranks. Pulled DTC codes again only thing that showed up is the ICP Circuit Low. hmm I wonder why haha
I pulled the upper fuel filter and cycled the key, fuel came running out. Not dumping, but a steady stream. I disconnected both batteries and let sit for 5 minutes. Still no start, and no hint of fuel coming out of the exhaust. And no new codes.

Whats next?

It has a HPO leak somewhere. STC, dummy plugs and stand pipes are the .most common failures on the 05+ trucks.

Its very hard to fix these truck without proper diagnostic equipment. Need to be able to check for injection pressure on engine cranking. #1 cause of no starts. If you can get the icp data and its not over 500 psi there is the no start. Next step is air checking the system to find the leak.

I checked the voltage of the ICP while cranking. It builds to .7 volts (~525 psi) after a few seconds of cranking. So its got enough pressure to start. Still not getting any fuel.
Ive been thinking about buying auto enginuty or a scan gauge 2. Im just not sure if the Scan gauge 2 is gonna do enough diagnosing.

Is there any tests i could do for the Crank position sensor and the cam position sensor? using a dmm?
