2013 F150 loss of RPM WOT

[TownsendsFJR1300]

maybe Townsends can comment of the fuel pressures.
I thought it was different than 40 all of the time.
he should know

I don't see spec's for the pressure in the Yamaha shop manual. Fuel does go thru a regulator BEFORE the rail...

PM sent to the OP

well now that I think more about this, It probably was not rail pressure I was thinking about.
maybe lift pump pressure on some other motor

The manual states how to check(Schrader valve), but I don't see any pressures. I'd think it'd be there, but I'm missing it...

The manual I found online was for a f150A, the manual tells you fuel pressure specs..... https://www.manualslib.com/manual/95...a.html?page=76

I also checked the fuel regulator as well and that is functioning as it should,

I guess I'll haul it out of the water and send it to the dealer......... THANK YOU EVERYONE FOR THE IDEAS AND SUGGESTIONS!!!!

STAY TUNED, I'll post back in a week or two when I something is found!!!

THANK YOU AGAIN!!!!!

I would get them to do a leak down test..or at the very least a compression test before anything else...check the general health of the engines heart.Easy and quick to do and cross that off the list.
