If your engine clicks but doesn't start, it’s likely the battery. If you turn the key and nothing happens, it might be the starter. Dim lights and electronic issues usually indicate a battery problem, while strange noises or smoke might point to the starter. Use a multimeter to check the battery voltage; it should be around 12.6 volts when fully charged. If unsure, consult a professional mechanic for accurate diagnosis.
