Good Job!! I am having the same problem, have replaced number 3 and 6 injectors. After 100 miles check engine light comes back on. When I unplugged wiring harness it was full of oil. Should have charged harness first!!

[@RobertsLife]

I found it will also leak down to the ECM through the engine harness. Mine had oil last November. I think the injector harness and leaking oil pressure sensor both contributed to it.

[@rooster7191]

Thank you Sir, Good Job!!

I replaced the injector harness. Truck runs great but it still has check engine light. Code says injector 6. I did a cut out test and all injectors are working. Truck runs great. Is there another harness between the injector harness and the Ecm? I called Cummins they want to sell me the engine wiring harness. Any suggestions?????

[@rooster7191]

@@RobertsLife how did you correct it? New Ecm? Or engine wiring harness?

[@RobertsLife]

​@rooster7191 I would pull the engine harness where it connects to the ECM, the plug gets full of dirt and dust, so if its hard to open I would use shop are to blow it out, I would definitely look at cummins quickserve for instructions for the engine harness to ECM plug before trying. If your ejector harness and oil pressure sensor leaked enough it'll leak all the way through the harness to the ECM.

You're very welcome.

[@PaulTanner-j9h]

what scanner tool do you have to clear the codes?

[@RobertsLife]

I'm useing cummins insite.

[@johnhazlett6764]

Is your pass thru plug lose or does it need to be tight

[@RobertDominguez-xq7yx]

It's supposed to be tight.

[@pedropedro2837]

Thanks sir very good video now do you have more engine power?

[@RobertsLife]

Thank you. The power feels the same.

[@ghumanrocks]

On my truck the oil is not leaking but I have codes for all 6 injectors and engine laking power any suggestion pls

[@RobertsLife]

You need to do more diagnosing for it, hook it up to cummins insite and do a injector performance test, check fuel pressure drop, injector leak test. Did they all come on the same exact time?

[@magnovska3979]

So did that fixed the code? I have the same code but for injector #2

[@RobertsLife]

Yes it fixed it.

[@RIOS247]

I have the same issue on my truck the plug is wet of oil outside but in I'm not getting any fault code yet my question is if I replaced just the gasket inside would that help to avoid oil leak thru there?

[@RobertsLife]

It could if you could find a gasket for it. I was told the harness needs to be replaced.
