The wiring diagram will be in the back of your service manual.

I'm just here for the beer.

Injectors are hot any time the key and bar switch are both in the run position. ECM grounds the circuit to cause them to open.

Do not go pocking around in there with a test light or analog voltmeter. You can burn out the injector drivers in the ecm. First thing to do is read the trouble codes.

System relay provides the power.

Unless someone has been dicking with the wiring, the fuel pump would also be dead if the system relay was not providing power.

You'll need a electrical diagnostic manual to fix it efficiently, there are diagnostic ladders that will walk you right through the problem to the source.

My point was many crashed bikes have the security system tripped,,, the injectors are not fired if this has occurred...
Follow the diagnostic tree from here..
There are no off the hip correct answers to efi issues.. each one is different
