Hi all.
I pulled into a gas station last week and my cbr954rr3 didnt start. I turned the ignition on and i couldnt hear the fuel pump prime. I then tried turning the engine on but nothing happend, all the normal display and running lights were on. While waiting for the tow truck I left the ignition on and all of a sudden i heard the fuel pump prime, i tried the key and she fired so home i went.
The following week i tried to start her but she wont fire. the fuel pump can be heard working and there is a definite spark at the plugs but she wont fire, the starter motor sound ok and the battery is fully charged,
Ive done a fuel flow check at the return hose and its delivering about half of what the manuel states. could the pump be faulty or should it still fire with only half the reccommended fuel flow?
Am i on the right trail of thought or could it be something other than the fuel pump?
Any ideas guys would be great

Buell is correct. Measure the voltage at the pump on the bottom of the tank. Could be corrosion causing it not to be getting full voltage. If it has 12vdc it is probably your pump.

Thanks for your replys. I cranked it over this morning and got it started. Im wondering if I flooded the engine when I briefly started it midweek.
Ile try it again tomorrow and see how it goes.
Will let you know

Cheers guys

Well she started like a dream this morning but im a bit worried about the knocking noise i can hear from the engine when the revs came down to normal idle speed.
Im pretty sure i havent heard this before and i havent adjusted anything while looking for the previous starting problem. It got quite loud at one point so I turned it off.
I know the fairings are all off at the moment and the engine will be louder but does anybody know if this is normal?
