Engine troubles Injectors? Wiring??

[jsengle]

Truck ran fine. left the house and boom check engine light on and lost power and running rough. limped it home. I lose the drivers side injectors. They work fine one minute then cut out next. Seems like wiring but dont know. Any suggestions?

Inspect the external harness connections to the valve covers (especially the driver's side, but check them all). Remove the oil cap and take a sniff. Does it smell like burned electrical insulation? If it does you have some burned/melted under-valvecover wiring harnesses. If all that happened to be good you could have a bad Injector Driver Module (more likely the wiring has burned/melted). Cheers!
