Some Saturn LW200 owners report experiencing starting issues despite having replaced the battery, fuel filter, and fuel pump relay. These problems may stem from a faulty starter motor that prevents the engine from cranking properly. Additionally, ignition issues, such as a malfunctioning ignition switch or ignition coil, can contribute to the inability to start the vehicle. Even with new components, owners might face fuel delivery problems due to clogged fuel lines or a malfunctioning fuel pump. Electrical problems, including bad wiring or a malfunctioning engine control module (ECM), can also hinder the starting process. Furthermore, poor quality or contaminated fuel may lead to starting difficulties, regardless of the new fuel filter. It is advisable for owners to consult a qualified mechanic to accurately diagnose and resolve these starting issues.
