Damien is correct, that the ECM controls the ground for the injectors.
With the key on there should always be power at the injectors. The ECM grounds the other side of the injector, to make the injector open.

The computer needs to receive a distributor reference pulse from the distributor module to trigger the injectors.
If you have no spark, don’t expect the injectors to work.
