Solution

1. Preparation

Gather all necessary tools and parts.
Ensure the vehicle is parked on a level surface and the engine is off.
Disconnect the battery to prevent any electrical issues.

2. Inspect Fuel Cap and Filler Neck

Remove the fuel cap and visually inspect for any cracks or deformities.
Clean the fuel filler neck with a suitable cleaner to remove any debris or corrosion.
Reinstall the cap ensuring it clicks into place securely.

3. Check Vapor Recovery System

Locate the vapor recovery canister and inspect for any signs of damage or leakage.
Test the purge valve for proper operation by applying vacuum and checking if it holds.
Replace the canister or purge valve if found faulty.

4. Test and Replace Fuel Injectors (if necessary)

Remove the fuel injectors using a socket set (ensure to relieve fuel pressure prior).
Inspect the injectors for clogs or leaks.
Clean or replace injectors as needed; ensure proper seating and sealing upon reinstallation.

5. Reassemble and Test

Reattach any components removed during inspection.
Reconnect the battery.
Start the engine and observe for smooth operation.
