Crazy idea... I'm reaching here... How about alternator test for AC noise and possible ECM issues because of AC noise damage? Yes you can pull the alternator and have it tested but it might give a clue to if the ECM possible was damaged by excessive AC noise. I've now had one report that proves that AC noise is possible on newer trucks.

You said you took the fuel supply line off the pump?  There are 3 lines to the cp3.   A banjo bolt, a quick disconnect and a steel line that you need a wrench for.   Which line is it your referring to?

 

You said the banjo bolt had minimal flow??   That is the pump return and minimal flow might be normal.
