Got a 7.3 with a dead miss. All 8 injectors were buzzing at the same noise level. KOEO code is #7 injector somethign something. I quickly glanced at it and saw a burnt wire going to the v/c harness. It's the one towards the back of the engine, probably #7 since it's on the right side. Anyways, i'm gonna tear into today, would a bad injector get the wires real hot to the point of melting the insulation? any body ever seen this?
