Default Fuel pump problem, maybe.

hi everyone
i have a new problem on my k3 when switching ignition on sometimes the fuel pump does not make its usuall whirring noise on pre startup check. if i turn ignition off and back on it is fine. but today it happen 3 times where it made a short whirring noise and stopped on fourth time it was ok. any ideas on what this might be is it a minor or major problem

thanks chris

Default Re: fuel pump !!!!!!!!!!!!!

Sounds like a lose connection to me, lift the tank up and have a look at all the connectors under there make sure there all fully pushed to geather. Also this could be a long shot but check the kill switch wire is fully connected because if its a bit dodgey it could be why it keeps cutting it out, Dom

same thing happens to my k3 after a cold night occasionally,
im assuming its down to the pump being sooooo cold having petrol around it all night, and probably needing to good clean out.

I've got Exactly the same thing, short buzz several times with the dreaded FI indication, before the proper loooong whirr, did you get a definitive diagnosis and solution?

I'd say more likely to be other safety systems on the bike, the pumps themselves tend to be pretty reliable

Agreed. I've seen a couple of failed pumps, but more often when the problem is traced to the pump itself it's been iffy connections/wiring.
If an SV650 has a flat tyre in the forest and no-one is there to blow it up, how long will it be 'til someone posts that the reg/rec is duff and the world will end unless a CBR unit is fitted? A little bit of knowledge = a dangerous thing.
