Hyundai Accent won't start after dying at stop light, fuel pump and sensors replaced on Hyundai Accent

Some Hyundai Accent owners report experiencing starting issues after the vehicle dies at a stop light, even after replacing the fuel pump and sensors. These owners often find that the immobilizer system may be malfunctioning, indicated by the immobilizer light not turning on, which can affect the car's security system. Additionally, problems with the battery and alternator are common, as a weak or dead battery can prevent the engine from starting. Even with a new fuel pump, some owners discover that low fuel pressure caused by a faulty fuel filter can hinder fuel system performance. Electrical and wiring problems can also contribute to starting difficulties, necessitating a thorough inspection of these components. Furthermore, issues with the throttle position sensor (TPS) and mass airflow sensor (MAF) may arise, impacting engine performance despite previous checks. Lastly, some owners report that their vehicles may enter limp mode, limiting speed and functionality, which signals an underlying issue that requires attention.
