Solution

1. Preparation

• Gather necessary tools and parts.
• Disconnect the negative battery terminal to prevent electrical shorts.

2. Check Fuel System

• Inspect Fuel Lines:
  • Visually inspect all fuel lines for cracks or leaks.
  • Tighten any loose connections.
• Replace Fuel Filter:
  • Locate the fuel filter based on the owner's manual.
  • Use a line wrench to disconnect the fuel lines (ensure fuel pressure is relieved first).
  • Replace the filter with a new one, ensuring proper orientation.

3. Repair EVAP System

• Inspect and Replace Purge Valve:

  • Remove any engine covers if necessary for access.
  • Locate the purge valve and disconnect the electrical connector.
  • Remove the valve and replace it with a new one, reconnecting the harness.

• Check Charcoal Canister:

  • Inspect the canister for cracks or damage.
  • Replace if necessary by disconnecting hoses and electrical connectors.

4. Fuel Injector Service

• Cleaning Injectors:
  • Remove the fuel injectors using a socket set.
  • Clean the injectors using a fuel injector cleaning kit or replace them if clogged.

5. Reassemble and Test

• Reconnect any components removed during the repair.
• Reconnect the negative battery terminal.
