Default Gsxr fuel pump sometimes doesn't prime

Hello All, Short version, 2003 gsxr1000 will not start sometimes, intermittent fuel pump will not prime. Takes a few minutes fiddling with the ignition to hear the fuel pump priming like it should before she starts up.


What could be the problem any suggestions ?

if you have to fiddle with the ignition then I'd start there...
see if you can get a loan of an ignition and go from there.

Wires from ignition barrel can rot, particularly where they are tied to the frame with a clip, just behind the Radiator (this happened me only a couple of months ago (but thats probably if its a winter hack as mine is). The fuel pump relay switch can give problems, I had to bypass mine and tie it into the kill switch (so if you want it to start priming you have to put the kill switch on (normally I would not use a kill switch but I have to every time I start the bike as such, or I could just leave it on but you cant have the ignition turned on with the bike not running as it keeps priming continuously, but its not a problem for me) good luck with it

Biggest suspect is the wiring block connectors down the sides of fairings. Probably got corrosion on them.
