You could use a paper clip , and push it into the back of the connector, do the same thing each end ,then join the wire to the paper clips

The only thing im seeing that would control the pump is that brown wire that has no voltage out of the relay, i did swap the relay and that didnt change anything so it cant be the relay thats bad. If there is 12v coming from ecu to the relay but nothing out of relay to pump what the hell is happening? this is confusing to me. Im not a expert but i understand low voltage and have some experience in electronic repairs, auto wiring, etc so im not a complete noob
The Brown wire only goes from the Fuel Cut relay to the fuel Pump, the Brown/Black wire from the fuel sensor goes to the instrument cluster

Have you checked the right handlebar switch for loose or broken connections? Does the headlight come on with the key and kill switch on?

Default Help needed

I'm kind of running into the same problem, bike ran fine today then just died, fuel pump won't prime, checked all fuses, bas, all relays, kill switch, heres the odd part, I have power going to the pump when its not plugged in but when it is plugged in I have no power at the pump itself, swapped out relays still no change, ran pump straight to battery and it kicks on, does anyone have any ideas
