I have researched this quite a bit since my bike messed up. No solution yet. It all started with fuel pump not coming on with no head lights, back blinkers staying illuminated. Bike will crank just fine but will not start. I have check all fuses, all relays test fine, kill switch is good, kickstand sensor good, grounds are good, and no messed up wires. I did test the bank angle sensor and i only get 4.2V on the hot and ground. Went back to relay and i am getting 12.3V going into it. The relay will not close. Fuel pump does work when jumped straight from battery. Also tried starting bike with fuel pump hooked straight to batter and no luck. I did spray starting fluid in and bike tried to start so I know I am getting spark. Any help would be great. I am stumped, and this is my primary mode of transportation since my truck is broke as well. Thanks in advance.

 

I found the problem. I have a bad ground connection on the BAS connecter on the harness side.

 

Thanks for posting that you found it and, what it was...most don't.
