Use the engine’s wiring diagram. the boat specific wiring is often not published

Got that on the first post, but without knowing what "motor" your working on we cannot help

I'm pretty sure its not a Briggs and Stratton but other then that I have no clue. Might be a Merc, VP, Ilmor, carb, efi, mpi :unsure:

Sorry, I mixed yours up with another
Don't know if it has a MEFI, 555 ECM or PCM but... if I had a serial number ...

The fuel pump is turned ON/OFF by the ECM applying a ground to one side of the relay coil. Trun key ON, energizes Main Power Relay (MPR) should hear a beep then fuel pump turns ON.

If it's not turning ON then check fuses, MPR relay, FP relay and then wire from ECM

Her is 555

2001 vintage 6.2 would probably be either MEFI-3 or the ECM. The service manual for the engine is what's needed and it will have the wiring diagrams.

To clarify for the OP . . . Engine wiring is not boat brand specific, they all use the same wiring based on the motor.
