fuel pump
« on: 29 May 2013, 02:14:44 pm »
pleae help  :o

went out 2 start my fazer today after about a 3 week lay up (battery has been charged though).

Turned ingnition and the fuel pump clicked away as normal, hit starter, turned over but didnt catch - this is normal, my fazer doesnt like being started if it has been riden for a week. BUT..when i let go of the starter, the fuel pump clicked away a bit more???

ignition off......back on, fuel pump clicks for 5 secs but kind of sounds like theres a loose connection (the sound isnt "even" if that makes sense)

so i did igntion on...fuel pump clicked for 5 secs...ignition off....back on...clicks for 5 secs....AND SO ON, it just keep clicking away always for 5 secs.

This isnt right is it??? never done it before and i thought the fuel pump just primed the carbs? so why is it doing it for 5 seconds every time the igntion is switched on??

The fuel pump shuts off when the float bowl level is correct.  Perhaps the pump is not getting the pressure resistance expected and so continues to operate for a while longer.  Could be symptomatic of an issue with the float needle seat O-rings, Phil.

However, start by checking the obvious things like electrical connectors, fuel lines and fuel filter before you assume it's inside the carbs.

ok. i do actually have a brand new fuel filter in my garage. So i will fit that, dont you have to remove the fuel pump to do so?? (if so, that will give me chance to spray up / clean the connectors)

thanks
