Technician A is correct because using a test spark plug can help determine if the issue is with the ignition system by checking for spark. Technician B is also correct because if a noid light pulses when connected to the injector harness during cranking, it indicates that the primary ignition circuit's triggering unit is functioning properly, as it's sending the signal needed to pulse the injectors.
