    Genuine and good

    Replacing the engine wiring harness is one of the best preventative maintenance items you can do to ensure all your sensors, glow plugs, and injectors have the best connection back to the PCM. Also be sure to check the wiring harness connector and the wiring that can rub on the left valve cover as this might be your issue.

    My old wiring harness has seen enough oil over the years that the wiring casing was disintegrating every time I unplugged things, leaving bare copper all over the place. Yikes!
