To tell the difference between a bad solenoid and a bad starter, listen closely when you attempt to start the engine. A faulty solenoid will often result in a clicking sound but no engine turn over. This means your battery is functioning, but the electric flow to the starter is interrupted. In contrast, a failing starter might produce a whirring or grinding noise, indicating it's receiving power but can't engage the engine properly. Sometimes, there might be no sound at all if the starter is completely dead. To further diagnose, try jumpstarting your car or testing the battery, as these parts can also influence the starter and solenoid's performance.
