I have 06 Cummings and have replaced the #6 injector but still receive a misfire code. I double checked the injector and verified that it ohms out like the rest of the injectors so I have read that it could be a fuel issue? Can the FCA be the culprit or would it more likely be the lift pump?

 

Did you Ohm at injector or from the harness.

I ask because the injector harness could be the issue, what code are you seeing?

Also what resistance are you seeing?

 

I ohmed at the injector and it ohmed the same as the rest. I don't remember what the ohms were

The harness is brand new also as I replaced two other injectors

 

What codes are you getting?
