no pulse to the injector

Good afternoon.

I attached the diagram for the number one cylinder.

If your power on one side, then you need to go to the ECM and test for power on the wire from the coil to the ECM. With the key in the on position, it should have power. If it does then the wire is good and only leaves the ECM as the failure.

It is the black and orange connector on the ECM.
