Few things are more frustrating than turning the key and hearing… nothing. Before you panic, here are the most common reasons your car won’t start.

1. Dead Battery

Symptoms: No sound at all when turning the key, or a slow cranking sound
Solution: Jump-start or battery replacement. Average battery life in Florida is 3 years.

2. Failed Starter

Symptoms: A single click (or rapid clicking) when turning the key, but engine won’t crank
Solution: Starter motor replacement. We can do this at your location.

3. Faulty Alternator

Symptoms: Car was running fine, then suddenly died. Battery warning light may have been on
Solution: Alternator replacement. The battery may also need charging or replacement.

4. Empty Fuel Tank

Symptoms: Starter cranks but engine won’t fire
Solution: Add fuel. If you’re stranded, Jeljo offers emergency fuel delivery.

5. Failed Fuel Pump

Symptoms: Engine cranks but won’t start, especially if it happens after the car sat for a while
Solution: Fuel pump replacement — requires professional diagnosis.

6. Ignition Switch Issues

Symptoms: Key turns but nothing happens, or electrical accessories don’t work with key in “on” position
Solution: Ignition switch replacement.

7. Security System Lockout

Symptoms: Engine cranks but won’t start, security light is flashing
Solution: Try using the key fob to unlock/lock the doors, then attempt to start again.

8. Blown Fuse

Symptoms: Specific electrical components don’t work
Solution: Check and replace fuses. Keep spare fuses in your glove box.

9. Faulty Crankshaft or Camshaft Sensor

Symptoms: Engine cranks but won’t fire, or starts then dies immediately
Solution: Sensor replacement — requires diagnostic equipment to confirm.
