Check fuses for light corrosion on the blades, and as for the plug connections, I've had pretty good results lightly spraying with CRC electrical cleaner and blow drying, with a light spray of Amsoil metal protector.

Something that sits a lot seems to develop more gremlins it seems.

Yea im concerned that since this was an engine swap, and it went from CAT to Cummins, theres alot of wire splicing back there, and I dont know if I'll ever figure it out...... but wanted to hear opinions incase it's ECU problem that stands out....
