ok look, this is very very simple.
there is a fuse off the battery, it has a 20 amp fuse in it, it feeds the efi circuit. it's red and white
the red white feeds the contact for the engine stop relay, when the engine stop relay is triggered it powers up the black/white that feeds the bank angle sensor relay
the engine stop relay is controlled by the kill switch, it is fed by a white/black which is from fuse D in the fuse box, the wire FROM the kill switch is a black wire, and it goes to the coil on the engine stop relay. the other side of the coil on the engine stop relay goes to the bank angle sensor as a red/white. the bank angle sensor connects this wire to ground.
first check for power on the red/white on the engine stop relay, if this wire is dead, then change the 20 amp fuse, if this wire is live, then check for 12v on the black wire on the coil side of the engine stop relay (from the kill switch) make sure the key is on and the kill switch is set to run when youu check. if there is 12v on the black wire, then make sure that the red/white wire is grounded through the bank angle sensor. or simply unplug the bank angle sensor and short the red/white to the green.
now you should be able to flick the kill switch and hear the relay click. it is possible that you are already experiencing this but your 20 amp efi fuse is blown and hence no action on the fuel cut relay.
once you have the engine stop relay working, chances are the rest of the bike will work. if not, then you need to look at the fuel cut relay. the black/white powers both the contact and the coil, so if there is 12v on that black/white wire, all you need is the ground signal on the brown/black from the ecm. if you have 12v on the black/white and no action on the relay, try a known good ecu.
chances are you won't get that far, because i suspect your issue is much simpler.
if you are confused, keep reading this post until you understand. absolutely 100% of what you need to figure out your problem is clearly explained above.
i'm going for a ride.
