Does anyone know how I could check that the ECM is sending a signal to the Injector? Im sure there is a tool out there for it but I do not have one.

I think you are talking about a noid light. It plugs into the harness at the injector. You crank the engine and the light flickers to show that the ECM is sending the fire pulse to the injector....Napa carries them....or any of the tool truck..ie: Snap on, Mac etc
