Solution

1. Preparation

Gather required tools and parts.
Ensure the vehicle is on a level surface and the parking brake is engaged.
Disconnect the negative battery terminal to prevent electrical shock.

2. Battery Inspection and Replacement (if necessary)

Remove the battery from the vehicle:
- Use a socket set to unbolt the battery hold-down clamp.
- Disconnect the positive terminal first, followed by the negative terminal.
Clean battery terminals:
- Use a wire brush to remove corrosion from battery terminals and cable ends.
Test the battery with a multimeter:
- A reading below 12.4V indicates a weak battery; replace if necessary.
Install a new battery:
- Position the new battery in the tray and secure it with the hold-down clamp.
- Connect the positive terminal first, then the negative terminal.

3. Fuel System Inspection

Replace the fuel filter if clogged:
- Locate the fuel filter and relieve fuel system pressure using the fuel pressure relief valve.
- Disconnect the fuel lines from the filter and replace it with a new one, ensuring proper orientation.
Test the fuel pump:
- If the fuel pump does not activate, check the electrical connections and replace the pump if necessary.

4. Ignition System Inspection

Remove the spark plugs:
- Use a spark plug socket to remove each spark plug and inspect for wear or fouling.
Replace spark plugs if necessary:
- Install new spark plugs according to the manufacturer’s specifications.
Check ignition coils:
- Inspect for physical damage; replace any defective coils.
