    check wiring under valve cover for insolation damage and wiring harness for oil leak from cylinder head down to ECM

    I just had to do this. Just as Pablo said, my injector harness that comes out the drivers side back of the engine head was leaking oIL and shirting it out. Injector 123 are in series and 456 in series. If there's oil leak then it's the very common to fail harness

    Need one injector, do them all at the same time and replace the wiring harness. It's better for your pocket long term.
