1-check your ECM ground. shown in SM ECM wiring schematic electrical chapter.
2-fuel pump circuit fuse is 10A and is in fusebox. R models behind right side of fairing...all other models under seat.
3-replace your KEY SWITCH/IGNITION relay. a failing relay will quite often cause the pump not to operate
4-last step is to: KEY SWITCH ON....KILL SWITCH ON...BAS CONNECTION CONFIRMED...TRANS IN NEUTRAL...SIDESTAND DOWN....gently wrap on frame spar as close to pump housing as possible with large rubber mallet and see if it comes to life. If so, the motor was frozen from sitting.
