    2005 XB9 City-X Fuel Issues

    I just purchased a 05 Buell XB9SX City X, changed all fluids - drained gas tank and cleaned - new battery - I cannot hear the fuel pump - so I checked the fuses - and relays - I think the fuel pump needs a rebuild, the bike has 516 miles & still has dealer tag, not wrecked just sitting inside a storage building with old gas and oil. I poured gas down by the air filter and the bike will run. Any other ideas or things I can try to troubleshoot?

    Thanks

    If it sat with old gas I would rebuild the fuel pump. More than likely the pump is bad and gummed up. You can try and pull the relay and put it back in and see what happens. If nothing then replace the pump. You can try lunatic he has them in stock. He has complete kits. Make sure your switch is in the run position and key on to hear pump run. Sometimes people forget to put in run position.

    He's totally right ^^^

    You can put a test light on the brown (IIRC?) wire at the pump to make sure its getting power before you order one, but Lunaticfringe does sell them at a good price to board members.

    You can check my guess at the wire color from the wire diagram in the service manual. They are available for free at Buellmods.com or Buelltooth.com

    Post pics, that seems like like a fresh ride

    2-stale moisture-laden fuel has been sitting there covering the pump assembly and its 2 filters for an extended period of time and caused problems. the problems are a frozen pump motor...rotted inlet strainer filter....clogged pressure-side filter. it will need to be removed and rebuilt or replaced...simple as that.
    3-you can try this to temporarily bring the pump to life but i would NOT run the motor with the pump and filters in this condition. as follows: put small block of wood under sidestand for slightly more vertical positioning. confirm that there is a bit of fuel in the tank...just a gallon or so will do. with key ON and kill switch to ON and battery CHARGED....kneel down to left side of bike where the pump is affixed to the frame rail. with rubber mallet or butt end of big screwdriver...wrap the head of the pump and/or the frame rail where the pump attaches. see if it comes to life. if it does you will hear it run and prime for a few seconds.
    this doesn't accomplish much other than to confirm that the motor is frozen fast and pump assembly needs rebuilt or replaced.
    Thank You - Yes I have replied to your email !!

    Ordered a fuel pump rebuild kit today (thank you lunaticfringe), now to find a motorcycle lift mod so I can remove the fuel pump.
