Fuel pump noise 2005 Buell xb9sx

There is a distinct sound that has a hissing component when you first turn on the key. It will last a second or two when the key is turned to the run position. When the engine started the sound will return and continue to produce the noise so long as the engine is running.

A relatively low noise is normal. If you are concerned check other like cars for the loudness level.

how to check your fuel pump

The pressure regulator on the fuel rail can also produce a sound when the fuel pump is running. The regulator is under the hood and any reasonable noise would not be a concern, A clicking sound is also normal throughout the fuel system when the engine is running created by the fuel injectors cycling.

Buell didn't make MOTO GUZZI.

Look at your fuel pressure - make sure that you have good CLEAN GAS in the bike, this is usually a fuel pump issue.

The spark plugs may be fouled. They often will fire when outside the motor, but will not fire when installed. Replace the plugs, inspect the plug wires for damage, and try again.

i would say...change out the gas put new premium in it and put some starting fluid on the spark plugs then give it a start it might just be bad gastry using seafoam on the bike you can find it at any auto store

I have a Buell M2 and a Buell Rirebolt.
When the batteries go, they leave us with clicking solenoids. There is enough power for ignition but not enough for the starter motor, hence the clicking noises.
That is possibly what you are experiencing.
Hope that helps.

It'll make a noise but it shouldn't be loud enough for you to hear it while riding unless you have ears like a cat. Ask a buddy to let you ride his fuel injected bike and see if you can hear his pump.

Good Luck

Now that you brought up the sound phenomenon, it is not a normal procedure for any fuel pump. To me it seems that the fuel pump is faulty and there is no fuel going to the carb. And that is why it does not start. And when you try too hard it does start with whatever you have and then goes off when you rev it up. So open up the fuel pump and check its bearings etc. The noise means that the bearings are not up to the mark.

disconnect fuel line from bottom of tank and allow to drain

Did you check the charging system? Sounds like when you ride it the battery drains. Could be you are drawing more amps than it is putting out. Sometimes folks run a lot of accessories, extra lites/ heated garments/etc on their Ulys. Once sitting for a few days it builds up enough to start.
