I have a 2009 ninja 650r that has power to the fuel pump but is pushing 15-17 volts I was wondering if anyone knew what could be up with it? Right now I’m kinda stumped but I know it’s not getting fuel

Hi I have an 09 zx10r and it will only start with jumper cables. When i pull the cables off the needle on the speedo goes crazy and the motor starts idleing rough then it finally just dies.. Any help would be greatly appreciated thank you.
