I see my IPR % is maxed out but that doesn’t explain the rest. I have a spare FICM that I’ll have my hands on late this afternoon. Can’t find any more wiring shorts. It does take a second for sync 1 and 2 to go to yes. Haven’t noticed that before, but haven’t been looking.
Power company is working on lines in my area and said expect outages on and off today, so I may disappear on and off.

I haven't used ForScan to check the vreference, but I bet it can/does. The codes are what makes me want to see that value.
As far as the no-start, it seems that the main issue is w/ the high pressure oil pressure.

Sorry I have been popping in irregularly. Been taking medicine - pretty sleepy today.
No Fuel Pulse Width indicates to me a FICM issue.
Are the IAT and cooling fan circuit codes gone? Did you repair the IAT short (was it IAT1 or IAT2)? Have you tried clearing the codes and seeing what comes back?
That said, you clearly are low on ICP (or the PCM thinks you are). I know that you tried w/ the ICP disconnected before, but try it one more time. I just can't believe you are actually at 51 psig on ICP since you have already done the dummy plugs, standpipes, and STC fitting. I know you tried it and posted the values in post #4, but turning the key off to get a screen capture somewhat obscures the whole picture. I guess it wouldn't hurt to make sure you have low pressure oil flow to the oil filter also.
Your codes sure seem to indicate an electrical issue also. You might just leave the EGR, ICP, and EBP sensors unplugged if you still have multiple sensor codes. They aren't required for starting.
I am still looking to find Vreference in ForScan.

Got my hands full with daughters/son-in laws/grandkids. Would rather spend time with them than work on my truck. BUT did repair IAT wiring problem. Still shows up on DTC’s. Here is my last. AND if you feel like it is the FICM i’ll Replace it tomorrow.

I guess I am going to have to change my mind on the FICM. I went back and saw that your earlier post when cranking w/ the ICP unplugged gave a FPW value.
I guess I am going to say that the high pressure oil readings are your top priority, That said, it still looks like you have an electrical glitch also and I really don;t know where to point you on that since you have looked in the area of the codes and you haven't found the vreference PID yet.
Are you able to do an air test on the HPO system where you are? Have you verified oil flow to the oil filter canister?

Don’t have hardly any tools here. I think i’ll have it towed to my little shop Tuesday and just enjoy my family for a few days. Mark it means a lot that you and Mike helped me. I’ll piddle with it over the next day or two and if I don’t get it, just tow it home. In the mean time if anything jumps out at you give me a shout.
I hope your cataract surgery doesn’t cause you any troubles, and the healing process is underway. Thanks to all and Have a great Memorial Day. Remember our troops.
Have a storm heading here anyway,so I’m not going to do much work on anything.

Changed FICM this morning with a known good one. Nothing. Cranked with ICP,EGR and Fan unplugged. Nothing. Relooked at fuel bowl filling and got diesel everywhere. Checked for bubbles none. First cranking I had FPW at 1.82. Next two crankings had no FPW. Images are with everything plugged in and last cranking.

Gotcha - looks like an air test is next, seems like the low pressure reading is real. Did you verify the LPOP filling the oil filter housing and that the drain plug works (closes) when pushed down? I figure it is fine, but you never know.
Thanks for the kind wishes (today things seem to be pretty good!), and hope you have an enjoyable Memorial weekend despite the truck troubles!
