To differentiate between a faulty starter and a solenoid, listen for a clicking sound when turning the ignition. A single click usually indicates a faulty solenoid, while rapid clicking suggests a battery issue. If there’s no sound at all when trying to start the engine, it is often a sign of a faulty starter. Inspect connections for any loose or corroded wires as well, which could impact both components. Testing these steps can help identify the root cause.
