That all the eco grounds are sound and that continuity exist with the cas. Put an LED on the number one injector connector and it gets a signal weather spinning the cas by hand or cranking the engine. I am getting a spark but just as I said before I feel it's a bit weak and that the injectors I know for certain are suppose to click much louder.
I'm guessing it could be fuel pressure and or poor grounding on the battery side of things.
