1. Ensure that the battery is properly reconnected. Make sure the positive and negative terminals are connected correctly and securely.
2. Check the battery terminals for any corrosion or damage. Clean the terminals if necessary.
3. Turn the key in the ignition and try to start the car. If the car doesn't start, try jumping it with another car.
4. If the car still doesn't start, check the fuses and relays in the fuse box. Replace any blown fuses or damaged relays.
5. Check the fuel level in the car and make sure there is enough gas in the tank.
6. If the car still doesn't start, you may need to have it towed to a mechanic for diagnosis and repair.
Here are some additional tips:
- Make sure the battery is fully charged before attempting to start the car.
- If the car has been sitting for a long time, you may need to press the accelerator pedal while starting the car.
- If the car starts but then stalls, try giving it some gas while starting it.
