High fuel pressure ruined the 4th


Recommended Posts

Like skurfer said, bad fuel pressure regulator.

 

As long as it doesn't go into power derate you are generally you are safe to run, it's just an annoyance.

Ironically, I got the exact same error yesterday while we were out. We cut the day short and came in. Note: my fuel pressure was up to low-70’s at idle and mid-60’s while underway.
