PLEASE HELP!!! 03 6.0 NO START

I have an 03 6.0 with 258,000 miles it has new stock injectors that were professionally installed around 2 years ago and a new/reman hpop installed professionally around 1 year ago.
Now onto my issue around 1 month ago my check engine light came on and showed a code that said replace injector control pressure sensor I cant remember the code number though. I went ahead and bought the new sensor and kept on delaying putting it in until I was on the way back from a road trip and I was driving and it just died on me didnít sputter or anything just died like I turned the key off. So then I replaced the icp sensor along with pigtail and tried to start but nothing happened just cranked and cranked and cranked. So then I thought ipr valve so I replaced that along with pigtail still nothing. So then I went on to replace camshaft position sensor and pigtail still nothing. I was at a standstill so I purchased the dash boss Bluetooth reader.

My ficm reads 48.5 volts key on and 47-48 while cranking.
ICP psi reads about 40 psi
ICP calculated psi reads around 150-200 psi while cranking
ICP volts read 2.2v I believe

So now from what ive read and researched that seems like a bad hpop but I donít wanna go tearing into it not knowing for sure. Anything else you might need to know ask but for now im lost and tired of riding my bicycle to work everyday.

Is your icp sensor in the high pressure oil pump cover? I think your reading your tool wrong. If ICP voltage is 2.2v you should be making 2000ish psi. What is your IPR %? You need a better scan tool or at least double check what your looking at.

When you replaced your IPR was the screen damaged or have metal debris on it?

ipr percentage was 15% during key on and then after i cranked it over it read 77%. however now it isnt reading icp voltage but might be because batteries are pretty dead. the icp sens is located in the back on the hpop cover. when i removed the ipr valve the screen was intact and had no debris on it.

If IPR maxed out at 77 percent and icp was 2.2 volts i do not suspect an icp system issue. Charge up your batterys, and double check your scan tool readings. Ficm voltage must be above 46v, rpm must be 150 or better and icp must reach at least 500psi among other things to start. Double check your readings with good batterys and report back!

Ok I charged up batteries my icp voltage is .23 volts static and .30 cranking. And I have 118 calculated psi and around 140psi cranking. My rpms are around 160 cranking. Also now my ipr maxed out at 85 % while cranking. Ficm is steady reading 48-49 volts.

Help me this sounds just like this girl's problem

You have described my problem almost to a T with just a few other things. I have replaced all the injectors, the HPOP (twice the first one was BAD!), got everything done drove awesome for about 8 blocks then died again and won't start. I have thrown lots of money at this and am at a loss as well as 3 mechanics.

Unplug your ICP and see what happens. Also the PCM only needs to see 100 rpm to start.
