Optimum Rail Pressure
#11
Ok, did you hook the rail pressure gauge up to see what the problem was or did you hook it up and then experience the problem?
Do you know about cycling the key to retrieve codes? If not, you turn the key from off to on off to on off to on and leave it in the on position the third time without ever starting the truck. In the odo window it will show what codes if any that are present. Codes can be present with or without a CEL. If no codes are present then it will simply say the word done and then go back to the odo reading.
