Solution

1. Preparation

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

2. Battery Inspection and Replacement

Check Battery Condition:
- Use a multimeter to measure the battery voltage.
- If below 12.4V, consider charging or replacing the battery.
Disconnect Old Battery:
- Use a socket set to loosen the battery terminal bolts.
- Remove negative (-) terminal first, then positive (+) terminal.
Install New Battery (if needed):
- Place the new battery in the battery tray.
- Connect the positive (+) terminal first, followed by the negative (-) terminal.
- Tighten terminal bolts securely (torque to manufacturer specifications).

3. Fuel System Check

Inspect Fuel Pump:
- Turn the ignition to the "ON" position without starting the engine.
- Listen for the fuel pump's humming sound; if absent, check the fuse and relay.
Replace Fuel Filter (if necessary):
- Locate the fuel filter (consult the service manual).
- Relieve fuel pressure before removal by using the service port.
- Remove the old filter and install the new filter, ensuring proper orientation.

4. Spark Plug Inspection and Replacement

Remove Spark Plugs:
- Use a socket set to remove the spark plugs from the engine.
Inspect and Replace:
- Check for wear or carbon buildup; clean or replace as necessary.
- Gap new spark plugs to manufacturer specifications before installation.
Reinstall Spark Plugs:
- Torque the spark plugs to the specified value (typically around 15-20 ft-lbs).
