Solution

1. Preparation

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

2. Fuel System Inspection

Step 1: Check Fuel Pump
- Reconnect the battery and turn the ignition to the "ON" position without starting the engine.
- Listen for the fuel pump's humming sound, which indicates it's working.
- If no sound is heard, replace the fuel pump.
Step 2: Check Fuel Filter
- Locate the fuel filter (usually along the fuel line).
- Disconnect the fuel lines (use safety goggles and cloth to catch any spillage).
- Replace the fuel filter if clogged.

3. Air Intake System Inspection

Step 1: Replace Air Filter
- Remove the air filter housing cover.
- Take out the old air filter and inspect for dirt and debris.
- Install a new air filter (ensure proper fit).

4. Ignition System Inspection

Step 1: Inspect Spark Plugs
- Remove the spark plug wires and unscrew the spark plugs using a socket.
- Inspect for wear or carbon build-up. Replace if needed (use OEM specifications).
- Reinstall new or cleaned spark plugs and reconnect the wires.

5. Final Checks

Reconnect the negative battery terminal.
Start the engine and check for any unusual noises or issues.
