So you are saying that there is power and no control to the injectors and if you add carb cleaner to the intake it runs, meaning that there is spark, timing is ok, and critical inputs are ok right?
well to me the next step is to go to the pcm and check for injector pulse at the pcm, if no injector pulse look for a shorted injector that burned the driver in the pcm, but that would be weird cause i dont think that the pcm uses the same driver for all the injector, we need a wiring diagram can you give us the vehicle info?
