On my '05 42 Fountain EX with 525's the starboard rear engine quit running. When you turn the key on you could hear the fuel pump running and you can clearly hear it on the port motor.
Now all you hear is the fuel pump relay clicking when you turn the key on. Swapped out the relays and no help. The engine will start with a little shot of starting fluid and then die. I know there is a mechanical pump, but is there an electric booster type pump, too. Where is it located.
Any help is appreciated, been out of the forums for a while.

Its in the fuel cooler box under the front of the engine. Drop the water hose in and out, then the two bolts holding the fuel box bracket on the front of the engine. After there are 4 7/16 bolts holding the plastic box to the metal bracket, un do those then pop the lid on the fuel cool box.

Check your wiring to your tether switch, fountain wired mine to the electric fuel pump rather than the ignition.
