If your car doesn't start but all the lights turn on, it usually indicates a problem with the starter system or a weak battery. The lights can turn on because they require less power than starting the engine. To solve this, check the battery's charge and connections, or try jump-starting the car. If these steps don't work, the starter motor or starter relay might be faulty and should be inspected by a professional.

  1. What are common reasons a car won't start even though the dashboard lights come on? Common causes include a weak or dead battery, faulty starter motor, bad starter relay, or poor battery connections.
