I have a 04 Dt 466 that is showing an injector isn't working . I have never done an electrical injector . Has a code saying an injector shorting to ground and I can feel the dead cylinder isn't working . Any thing I need to test for or how to remove the solenoid and injector ? Thanks in advance .
Might check the under rocker cover wiring. If one of those plastic wiring guides is broke or out of place, a wire(s) can rub through and short to rocker cover or etc.
exactly what Fastback said. Been there, done that.
Pull the valve cover off and it's pretty easy to check and see the wiring. Make sure you drain the fuel rail and the HP oil rail before removing an injector. pulling one out is pretty self explanatory once you get the valve cover off. :)
