Solution

1. Preparation

Gather tools and parts needed for repair.
Disconnect the battery to ensure safety while working on electrical components.

2. Fuel System Inspection

Fuel Pump Check
- Remove the fuel pump relay from the fuse box.
- Use a multimeter to check for voltage at the fuel pump connector while turning the ignition to the ON position.
- If no voltage is present, trace wiring back to the fuel pump relay and check for continuity.
Replace Fuel Filter (if necessary)
- Locate the fuel filter (often near the fuel tank).
- Relieve fuel pressure by removing the fuel pump relay and starting the engine until it stalls.
- Disconnect fuel lines from the filter (use line wrenches to avoid damage).
- Install the new fuel filter, ensuring proper orientation and tight connections.

3. Ignition System Maintenance

Inspect Spark Plugs and Coils
- Remove spark plugs using a socket wrench.
- Inspect for wear, carbon buildup, or damage; replace as necessary.
- Check ignition coils for cracks or damage; replace any faulty coils.

4. Air Intake System Cleaning

Clean Air Filter
- Remove the air filter from the air intake housing.
- Inspect for dirt and debris; clean or replace as necessary.
- Ensure the air intake housing is free from obstructions.

5. Reconnect and Test

Reconnect the battery.
Start the engine and monitor for proper operation.
Perform a test drive to ensure stalling issue is resolved.
