Serious question about injector cups on 7.3s

I fought a stalling issue on my 2000 F-250 for 3 months. Changed the IPR, ICP, even the HPOP. Nothing fixed it. Then a buddy told me to pull the valve covers and check the glow plug harness. Found a pinched wire grounding out on the head. Fixed it with 5 bucks in shrink tube. Has anyone else run into electrical gremlins that made you chase fuel parts first?

Bet you 20 bucks half the people chasing fuel issues on these trucks actually have a chafed wire somewhere. UVCH harnesses love to rub through on the valve cover gasket bolts. Always start with a visual on that passenger side rear corner.

Saw a guy on YouTube find that exact problem, lol.
