If your car won't start but the radio and lights come on, the issue is likely with your battery or starter. The battery might have enough power for small functions like lights and radio, but not enough to start the engine. Check the battery connections for corrosion or looseness. If that’s not the problem, the starter or ignition switch could be faulty. It's best to have these components inspected by a professional to ensure accurate diagnosis and repair.
