VATS is the only thing in the PCM that will keep the injectors from working. How did you test them? And how did it run if they aren't working?

I had made a tester/cleaner. I just connected it to each injector and hit the button and I could hear it spray. After testing each injector I hit the starter and the truck ran using the fuel I sprayed I guess. Each injector has 12+ so I know it’s the ECM. I checked all the grounds and they are good.

I did turn vats off in the tune under OS tab I believe. Any where else I need to check or do?
