Does anyone know what the voltage is on pin 5 and when is it powered (allow fuel or shut off fuel)? Also will a test light put too much load on the ECM hooked to this wire? I want to check this line when the engine is running to see if the ECM is causing this input to momentarily shut off fuel causing my engine to cutout (miss).
