Also, I don't know if this option is suitable for your circumstance but others have bypassed the fuel pump relay to defer a TIPM replacement. I say defer because chances are you can expect more TIPM grief in the future. Not that my tea leaves said so.

Appreciate the info. Whatever the fix is, I’m thinking it’ll be my last ditch effort to keep this truck. It’s served me well, but the mileage is definitely getting to it.

Update, finally got the truck back. Replace the TIPM along with the serpentine belt which had a massive rip in it and various maintenance needs parentheses transfer case differential, etc. We’ll see how long I can keep this truck alive!
