Hello, which side of the engine did you replace the injector on, driver or passenger side? Thanks
Customer: replied 7 years ago.
#1 cylinder
Expert:  Dieseljunky2 replied 7 years ago.
I want to make sure that it was number one that was changed, do you know which side was changed? Was the Ford dealer the one who changed the injector?
Customer: replied 7 years ago.
passenger side very front

Was the injector wiring harness inspected closely? There have been many problems with the harness chaffing on different parts of the intake manifold and where it goes under the turbo, as well as where it comes out the FICM, shorting out on the manifold.

no i havent checked that, if thats good any other ideas
Expert:  Dieseljunky2 replied 7 years ago.
There are only 3 parts involved in the code you have. The injector, the wiring harness, and the FICM. The injector harness is only for the injectors and can easily be removed for inspection. The injector and Ficm have already been replaced. The wiring harness is all that is left. Thanks
