  • Cannot start - fuel pump and/or starter

    Dear fellow riders!

    I'm dead in the water. My trust XV1600 suddenly can't start. Here's my observations and troubleshooting so far:

    When I turn on ignition I'm not hearing the fuel pump build up pressure as it usually does. When I hit the starter button absolutely nothing happens (not even clicking). Plenty of power on battery.

    I have worked my way through troubleshooting from the manual and it actually seems the fuel pump is not working. According to the manual I should be able to measure a resistance of 1.6 - 2.0 ohm. I get nothing. I have tried applying power directly and nothing happens.

    What puzzles me though is the starter does not crank. I imagine starter will crank regardless of a faulty fuel pump? Which leads me to think it's actually not the fuel pump anyway - or perhaps something else is wrong as well?

    Any advice or similar experience is VERY much appreciated it! (especially whether a faulty fuel pump will affect the operation of the starter as well).

    Thanks! - ride safe.

    When did it last run and start well? Just because a battery measures 12 volts does not mean that it's adequate. It needs to be tested under a load. Make sure all your cables are tight.

      Check all fuses (not just looking testing with a meter) and try jumping starter solenoid lead to bump starter.

        Check the relay fuse and the battery cable connections.

          Measure battery voltage as it sits and while cranking

          Check relay fuse... Sounds like it may have popped

          Fuel pump OR fuel pump relay sounds like one or both of those is bad also since it's not energizing with key on

            if the carb is not calling for fuel the pump will not come on. Check fuses as others have said a blown 30 amp main fuse will stop everything from working. If they are all good you likely have a bad starter relay. jump a screwdriver across the 2 big post with the key on to see if it starts or cranks over.

              As others have said, check fuses and cables to make sure they're clean and tight. Do the needles sweep or any lights come on when you turn on the key?

                Thank you for all the inputs!

                It turns out it was actually corrosion on the starter switch. Once cleaned it came alive! (note to self: don't get tunnel vision - you almost wrote off the fuel pump)
