So I'm having a really hard time keeping up with the other thread and I have a lot of new information so I wanted to start fresh. I'll be sending in the FICM to Ed if the oil caps don't solve the issue. My elm unit came in today and I bought the extended PIDs for it. Not 100% sure what I was doing but this is what I was able to figure out on my own:
Those are before and after data and the codes I have/had.
FICM rebuilt by FICMREPAIR.com and has the 100HP tune on it. The truck had it before the rebuild and it ran fine up until the issues that caused me to send it out.
FICM relay has been replaced with a brand new one from FICMREPAIR.com
Pull off the engine fuel filter lid and cycle the key, fuel should flow out of the bowl.
This has been done on the upper bowl only and filled/overflowed with no issues. It was full when cap was removed. I'll be checking the other one tomorrow.

I think. I posted the PIDs tonight that I gathered and will get more if needed/possible.

About to be doing this sadly.

Have you tried holding the starter just a tad longer?
Are you getting 150 rpm?

Also, you need to verify that you have Cam/Crank sync.
The above conditions, along with 150 cranking rpms (for a few seconds, not a fraction of a second), 500 psig ICP, sufficient battery voltage, and sufficient air and fuel and you should be starting (assuming you have good compression).
Does the secondary fuel filter bowl fill fairly rapidly (KOEO)?
Have you tried the bubble test (cranking with a half full fuel bowl w/ the FICM relay removed)?
Are you sure the air filter is allowing proper air flow (filter minder check)?
Getting any significant exhaust smoke on extended cranks?
Things that were mentioned before:

To get FICM sync, you need cam and crank sync first. You should be able to see those on a gauge, don't know if the Edge will read it though, I'm not familiar with its capability. Once it receives cam/crank sync, the FICM sync turns to a yes/1 and fuel is commanded.
FICM SYNC (needs to say “yes” when cranking)
FICM L power (needs to be above 11.5 volts)
FICM V power (needs to be above 11.5 volts)
FICM M power (needs to be 45 volts or above)
ICP or injection control pressure, needs to match the ICP Desired reading.
IPR or injection pressure regulator (should not reach and maintain 85%
Sure will. You need an IPR reading to show oil pressure to the injectors. No or low oil pressure and she won't start. Don't look at the dash gauge either, that thing is useless.
I see RPM @135... not enough.
Injector Control Pressure, 1.4v, 2.0v... is enough.
FICM logic at 9.3v is bad.
FICM output at 48v is good.
Injector Control at 43.75% is good.
Looks to be hitting thise numbers for just a second or so. And your not showing sync for crank/cam/FICM. They need to be sync yes/1 before it will command fuel.
Those readings are not easy to read in the setup you have and most are useless. Air/fuel ratios, absolute pressures, all need to be in PSI if there going to be useful.

The ELM device for Torque?
Yes, ELM with DashCommand and extended PIDs. I'll swap it to PSI in the morning and try again. What PIDs can I take off from that (long) list to make this easier?

I think Randy's got it for you right here in red. It's probably not getting sync because it's not cranking fast enough. Is your voltage still dropping that low with new batteries, etc???
