I road my bike one day, and the next day, it wouldn't crank. When I flip my kill switch, I do not hear the fuel pump prime. I've bypassed my BAS to see if that was the issue. My relay is clicking and has ~12v when I check it with the multimeter. The 20a fuse at the battery is good. I switched it out just so that if someone asked me if I was sure, I could say yes. The wiring harness that connects to the fuel pump doesn't get 12v when I flip my kill switch.

Could this be anything else but a bad wire or ECU issue? I've tried to retrace my steps on the wiring diagram, but I don't see anything else that it could be.

 

Did you do a DIY kill switch or is it a factory switch?
