900RR fuel pump not running ?

Hi guys just a quick one, ive come to start my 95 blade for the first time since i bought it a few weeks ago and it turns over fine but im not hearing the fuel pump running ... what exactly stops the fuel pump from running ? im presuming it starts as soon as ignition is turned on ? im hoping there is a really simple answer which is why i posted here before diving into the loom with the Fluke. thanks in advance

The fuel pump will start when you press the starter button.
When the engine is running the pump will continue to run.
Was it running when you bought it?

Thank you bladeracer, this is the information i was really looking for ! i wasnt sure WHEN the pump was supposed to run so basically only when the engine itself is spinning ...

no it had been sat for a couple of years and hence battery was knackered, fuel old etc etc. so i offered him bottom price with regards to all this.

I was actually struggling to use the search function using two words (it never finds any results!) but i tried one word last night (much better idea) and found a thread on bypassing the pump. I tried this out and the bike fired up with a little choke so its all good.

thank you again mate !

Re: 900RR fuel pump not running ?

i unplugged the fuel pump and ran the bike with the fuel straight to the carbs. once running i checked at the socket for the pump plug and had 15 odd volts there so looks like fuel pump could be fine. thanks for clearing that up bladeracer

He means he bypassed the pump so the fuel is gravity-fed.
The pump is under the tank. You only need the pump when the fuel level in the tank falls below the level of the float valves in the carbs.
