The crazy thing is the truck was being driven daily. It started missing and got worse over two weeks before they brought it in. I fixed the engine wiring and he ate on it that night again. Other issues appeared and I found him above the fuel tank eating wires around that area. After the wiring was fixed, the truck was on the road for about a week before a lifter broke on the first cyl he ate the injector wires on. Could be a coincidence but who knows. Thanks for watching!
