Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the battery to ensure safety while working on electrical systems.
Gather personal protective equipment such as gloves and safety glasses.

2. Fuel System Inspection

Check Fuel Pump Functionality:
- Locate the fuel pump relay in the fuse box and test it with a multimeter for continuity.
- If faulty, replace the fuel pump relay.
Inspect Fuel Lines:
- Check for kinks or leaks in the fuel lines. Replace any damaged sections.
Replace Fuel Filter:
- Disconnect fuel lines from the filter using a line removal tool.
- Replace the old filter with a new one, ensuring the flow direction matches the fuel flow.

3. Ignition System Check

Replace Spark Plugs:
- Remove the spark plug wires and use a socket wrench to remove old spark plugs.
- Install new spark plugs, ensuring they are gapped correctly as per manufacturer specifications.
Test Ignition Coils:
- Remove the ignition coils from the spark plugs.
- Test each coil using a multimeter for resistance. Replace any coils that are out of specification.

4. Air Intake System Inspection

Replace Air Filter:
- Remove the air intake cover and take out the old air filter.
- Install a new air filter, ensuring it seats properly in the housing.
Inspect Throttle Body:
- Remove the throttle body from the intake manifold.
- Clean the throttle body with an appropriate cleaner and a soft cloth, removing any carbon buildup.
