To distinguish between a faulty starter and a bad solenoid, listen closely when you attempt to start your vehicle. If you hear a clicking noise but the engine doesn't turn over, it's likely the solenoid. However, if you hear nothing or a whirring noise without the engine starting, the problem might be the starter itself. For a more definitive test, you can bypass the solenoid by directly connecting the starter motor to the battery using jumper cables. If the starter motor engages, the solenoid is likely the issue; if not, the starter might need replacing.
