1. Dead Battery:
- Check the battery terminals to ensure they are clean and free of corrosion.
- Try jump-starting the car using another vehicle or a portable jump starter.
2. Faulty Starter Motor:
- Check the wiring connections to the starter motor.
- If the connections are secure and the battery is in good condition, the starter motor itself may be faulty and may need to be replaced.
3. Bad Ignition Switch:
- Check the electrical connections to the ignition switch.
- Try turning the key in the ignition multiple times or jiggling it slightly while turning it to see if it makes any difference.
4. Neutral Safety Switch:
- This switch prevents the car from starting if it's not in neutral.
- Check the wiring connections to the neutral safety switch and ensure the switch is functioning properly.
5. Faulty Fuel System:
- Check that there is enough fuel in the tank.
- Listen for the fuel pump engaging when you turn the key to the "On" position. If you don't hear the fuel pump humming, it may be faulty or damaged.
If none of the above steps resolve the issue and your Subaru Impreza WRX still doesn't start, it is recommended to have the car diagnosed by a professional mechanic or at a Subaru dealership to identify the exact cause and have it repaired.
