Hi, I have a PO204 code. Injector is stuck open. I removed the fuel rail and turned key to on. #4 injector would not stop spraying. I switched #3 and #4 injector and the same thing happened. So injector is good. Car runs bad but runs, on the other three injectors when I unplug #4 injector. I think I have a Poss injector wire grounding out to metal or a bad ECU. Does that sound correct? I need a wire diagram for my #4 fuel injector to # ? ECU pin so I can bypass my wire harness for know. If that works will sodering the wires back together, be the best way to fix the wires?

A Dodge wiring diagram is available in the link in my signature for the '03-'05 FSM.

 

The PCM controls the injector VIA ground if I remember correctly. Sounds like the injector PCM ground is shorted to ground before the PCM.

 

Thanks I found this else where

POWERTRAIN CONTROL MODULE C2 - BLACK/ORANGE 38 WAY #11 K14 18LB/ BR- fuel injector #4 driver. So it's the PCM pin #11 and it's a BROWN wire? I'm still trying to get the 03-05 FCM link to load. What's the K14 and 18lb mean?

 

Hi If I disconnect the bad #4 injector connector and sparkplug. Can I drive the car home it's about six miles, on hilly paved back roads?

Thanks
