Solution

1. Preparation

Ensure the vehicle is parked on a level surface and the engine is off.
Gather necessary tools and parts before starting the repair.
Disconnect the battery to prevent electrical shock.

2. Fuel System Inspection and Repair

Check Fuel Pump Functionality
- Turn the ignition key to the "On" position without starting the engine.
- Listen for the fuel pump engaging (a humming sound).
- If no sound, test the fuel pump relay and fuse for continuity.
Replace Fuel Filter (if clogged)
- Locate the fuel filter; it’s usually along the fuel line.
- Disconnect the fuel lines using a line wrench.
- Remove the old filter and replace it with a new one, ensuring proper orientation.

3. Ignition System Repair

Inspect Spark Plugs
- Remove the spark plug wires carefully.
- Use a spark plug socket to remove the spark plugs.
- Inspect for wear or fouling; replace them if necessary.
- Gap the new spark plugs to manufacturer specifications before installation.
Test and Replace Ignition Coils (if faulty)
- Use a multimeter to check the resistance of each ignition coil.
- Replace any coils that do not meet the manufacturer’s specifications.

4. Throttle Body Cleaning

Remove the Throttle Body
- Disconnect the air intake duct.
- Unbolt the throttle body from its mounting.
- Disconnect any electrical connectors.
Clean the Throttle Body
- Use throttle body cleaner and a lint-free cloth to remove carbon build-up.
- Ensure the throttle plate can move freely.
Reinstall the Throttle Body
- Reattach all components in reverse order.
- Tighten bolts to the manufacturer’s torque specifications.
