If a noid light test light remains on and does not flash on the ground side while the engine is cranking, it could indicate a problem with the fuel injector circuit. This issue may be caused by a short to power, where the injector is continuously receiving voltage, or a fault in the engine control module (ECM) that is not providing the necessary pulsed ground signal to the injector.
