Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is cool.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement

Inspect Battery Condition:
- Use a multimeter to check battery voltage; it should read between 12.4V to 12.7V.
Replace Battery if Necessary:
- If the battery voltage is low, remove the battery using a socket set.
- Install a new battery (if needed) and ensure terminals are tightened.

3. Fuel System Check

Test Fuel Pump:
- If the pump does not operate, locate the fuel pump relay and check for functionality.
- Replace the fuel pump if it fails the test.
Replace Fuel Filter:
- Access the fuel filter according to manufacturer specifications, which may require removal of underbody shields.
- Install a new fuel filter ensuring correct orientation for fuel flow.

4. Ignition System Maintenance

Inspect Spark Plugs and Coils:
- Remove spark plugs using a spark plug socket; inspect for wear or carbon buildup.
- Replace spark plugs if necessary, ensuring they are gapped to specifications.
Check Ignition Coils:
- Test each ignition coil with a multimeter; replace any defective coils.

5. Starter Motor Inspection

Check Starter Operation:
- Access the starter motor; ensure all connections are secure.
- If the starter is weak, replace the starter motor.
