Common reasons for a car engine not starting include a dead battery, faulty starter motor, empty fuel tank, or issues with the fuel pump. Check the battery first by turning on your headlights; if they're dim, the battery may be dead. Ensure there's fuel in the tank and listen for a humming sound when the key is turned to 'on'—a sign the fuel pump is working. If these steps fail, it might be time to consult a mechanic.
