I have a 2001 RC and one day I came out to start the bike , I did not hear the fuel pump prime . I pushed the starter switch back and forth and it primed ! It started to where i needed ro push the switch 15 to 20 times to hear it finally prime ! I purchased a new oem switch and it does the same thing . Any suggestions guys ?
my fuel pump prime problem turned out to be a crappy connection through the pump. Theres a brass rivet underneath that green exoxy stuff. I had to re tighten the connection and re epoxy it. Not fun. Nor did I have confidence its not going to loosen up again and leave me stranded somewhere.
The fuel pump is one of the last things on my list. So many other things that are tied to it that need to be checked first.
Did you try swapping the Highbeam relay. Put the fuel cut relay into the highbeam relay and cycle the highbeam a few times. Same works with the bank angle relay.
Pilot has a good point about connectors. There's a connector on the left side near the gas tank hinge that should be checked too. As I recall, it's a 3P connector.
So I'm out in the garage tonight with my girlfriend looking over the bike and she says why don't you for giggles switch the headlight relay and the bank angle relay! You can really feel the fuel cut off relay when the Fuel Pump comes on intermittently and very little with the bank angle relay ! So I did that and now you can feel both really click and the fuel pump primes like a mofo! I tried it for 45 min intermittently on and off and it primed everytime ! I HOPE THIS WAS MY ISSUE I'm ordering two more relays just in case and I'll put a picture up on Amazon if anybody else wants to order them also
