Starboard engine quit yesterday at WOT, that was fun, Restarted but would only run a few minutes with limited RPM. Got her home have no fuel pressure and no power to pumps. Good engine has power on one of the terminals with key on. Before I start pulling apart does anyone know if there is a breaker somewhere. Whire to pumos goes into main harness.Engine will run if a small amount of fuel is poured into it. Thanks Tim

Check the pump relay on the motor... one wire will be hot all the time. one wire will get hot with the key. one wire will be the power to the pump . one wire is ground.
You will have a couple relays together... 2 or 3 I can remember
Unplug 1 relay at a time on the good motor to find the right one if you need to figure out what relay to look at
