I have a '03 mobuis dd fuel pump does not come on when you turn the key. After banging head for hours and taking apart wiring traced to the temp. sensor put in a used one and fired right up. so after putting in a new one back to same original problem. Put in the used one and nothing. boat just cranks no fuel. Any help would be great.

Is your engine carbureted or fuel injected?

Put a test light on the two wires on the fuel pump turn the key on and see if the light comes on. If the light comes on and you don't hear the fuel pump come on I would think it would be a bad fuel pump
