Hello. My name is ***** ***** I will be helping you today.It usually means the cam sensor is bad. Sometimes its the wiring to the cam sensor. Do you have a multimeter for testing?
Customer: replied 1 year ago.
Yes I have multimeter
Expert:  Wayne Crawford replied 1 year ago.
Unplug the cam sensor just below the injection pump. Check for 5 volts on the Dark Green/Orange wire and on the Dark Blue/Red wire. Check the Light Blue/White wire for a good ground. Let me know what you get on those.There is also a TSB for reflashing the ECM to address this but that is when its intermittent.
