Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery using a wrench to prevent electrical shorts.

2. Battery Inspection and Replacement

Remove Battery Cables
- Use a wrench to loosen the negative (-) terminal first, then the positive (+) terminal.
Inspect Battery Condition
- Check for corrosion, leaks, and ensure it holds a charge (12.6 volts or more).
Replace Battery (if necessary)
- If the battery is faulty, replace it with a new one of the same specifications.

3. Starter Motor Replacement (if needed)

Remove Starter Motor
- Disconnect wiring harness and mounting bolts using a socket set.
Inspect or Replace
- Test the starter motor and replace it if it fails to engage properly.

4. Fuel System Check

Check Fuel Pump Operation
- Turn the ignition on (without starting) and listen for the fuel pump priming.
Replace Fuel Filter (if applicable)
- If the fuel filter is clogged, replace it according to the manufacturer's specifications.

5. Ignition System Maintenance

Remove Spark Plugs
- Use a spark plug socket to take out the spark plugs for inspection.
Inspect and Replace
- Replace worn spark plugs with new ones if necessary, following torque specifications.
