Are you having a hard time starting? When you go to start it, how quickly does the oil pressure go up on the truck? (Cold Start.)

I'd remove the sender from the top of the HPOP resi and install a mechanical gauge before doing anything else. IIRC the sender is 1/8" NPT so even a cheap 0-150 psi air compressor gauge will work for testing purposes.
