    Default 8.0 KW Westerbeke Fuel pump wont activate

    I have a 8.0 KW Westerbeke gen that the fuel pump will not activate and prime accordingly therefore causing the engine not to start. I have replaced both relays and the Start Stop switch but niether has helped. The reading is less than 1 volt at the pump however, I am able to jump power to the pump and it work.
    Any ideas on what is causing the low to no volts at the fuel pump?

    You need to check every connection between the fuel pump and the battery including grounds. Problem is probably corrosion in a connector, fuse holder, etc. Make sure you get 12 volts to the relays and switch. Follow the wire where you're getting 1 volt back to it's connection and read there. If you read 12 volts at the other end then either you have a bad wire or a bad ground. And so on...

    Had to call a professional.. turns out there is a bad diode on the overspeed sensor board that needs be replaced as well as an issue between the remote start panel and the generator.. still to be found.
