I am newly registered, but have been scouring this forum for a few weeks trying to resolve my problem. I have found several related scenarios, but I have tried about everything I have found. Any assistance or ideas is appreciated.
I have a 2016 F-250 (complete delete) with just over 52,000 on the odometer. I changed the oil and fuel filters two weeks ago, I drove the truck about 1.5 miles and parked it at my house. The next day the low fuel pressure warning came on when I started it and I have a P01C6 (fuel pressure sensor A circuit high). No issues starting the truck, no CEL, and it seems to run fine…..but I only drove it a short distance hoping the light would go off.
The lift pump sounded like it had air in it (gurgling noise), so here is what I have done so far:
I have ruled out a sensor since I can hear the gurgling in the lift pump. This has never occurred prior to me changing the fuel filters so I’m assuming it is somehow related, but I replaced everything at least once. The low fuel pressure warning, P01C6 code, gurgling from the lift pump are all still occurring and I’m at a loss.
I am hoping someone has had a similar experience or can point me in the right direction.

The lift pump sounded like it had air in it (gurgling noise), so here is what I have done so far:
- changed out both filters again….and the lower/frame mounted filter housing is 100% on all of the way.
- replaced the lift pump; it came with a new housing and fuel filter (factory sealed)
- purged the fuel line at least a dozen separate times, to include connecting a hose to secondary filter in attempt to push the air out
- I have unconnected and reconnected all of the fuel lines, everything is on tight and not leaking fuel
- I have never used additives, so there shouldn’t be any foil/cardboard in my tank
- I clear the code and it immediately comes back
