2008 6.4 Got this code yesturday and the truck idled rough and died started it back up and it does it intermittent is this possibly just a sensor change under the valve cover or fuel pump ? I was going to change the sensor tomorrow and go from there. This is the only code I could pull fuel rail pressure was right at 5750 at ideal and went up to 7-8000 just giving it a little fuel the voltage for the sensor is bouncing from 1.18 - 1.22 volts running koeo .50

 

Iirc sensor and under valve cover harness.

 

Ok I changed the sensor and the wet harness but when I pulled the sensor I thought fuel would come out but it was dry ? Is that normal

 

You will only have fuel there if there is pressure at the line. So what you have is normal.
