2022 23ZX Primary fuel pressure low fault

[Jwolfe]

Anyone ever have this fault? Primary Fuel Pressure Low, SPN 94, FMI 1.
I also had STFT 1 and 2 low limit, SPN 4238, FMI 1.

The boat is still working but has a power loss under full load, it has a hard time getting to surf speed of 11 and maintaining it.
Any help would be appreciated.

Low pressure will do that. Usually it's just the regulator that fails on top of the in tank fuel pump.

The the STFT limits may be from ECM tryin to pull out injector pulse width timing or you also jave a misfire as well. Injector kill test with Diacom is best way to confirm IMO.

If you have a fuel pressure tester you can screw into the to of the Schrader at your fuel filter and test. Fuel pressure should be 58psi plus or minus 5PSI. If you don't have a FP tester they are relatively cheap.....or take it to your dealer for warranty work
