Please I need a help on how to test voltage to the injector pump solenoids. I don't think ecm is energizing them but I want to be sure. Three out of the six injectors share a common positive and so for the other three but each with a negative supply. I want to know if I can measure the positive to ground and get battery voltage when the ignition is on. Thanks. Attached is the engine ecm schematic.
