Sorry for the delay had to pick up my daughter she was sick at school. Has the harness been checked as well as the ECM for this issue?
Customer: replied 4 years ago.

I did not change the harness. However I made sure the part going to the pump is not short circuiting anywhere and I checked the resistance and compared it to a working was correct. I also reprogramed the ecm after fitting a new diesel pump. Problem still exists

OK at this point if the fuel rail pressure sensor was replaced there has to be an issue with the injectors or the ECM itself .Have these been checked for this issue?
