Disconnect the battery to ensure safety while working on the electrical system.

Tools Required:

OBD-II scanner
Fuel pressure gauge
Socket set
Torque wrench
Screwdrivers
Safety goggles and gloves

2. Inspect and Replace Fuel Cap

Remove the fuel cap and inspect for proper sealing and damage.
If damaged, replace with a new fuel cap.

3. Test and Replace Fuel Pump (if necessary)

Access the fuel pump by removing the rear seat or bed (depending on model year).
Disconnect the electrical connector and fuel lines from the fuel pump.
Use a multimeter to test the fuel pump's electrical connections for voltage.
If no voltage is present, check the fuel pump relay and fuse.
If the pump is faulty, install a new fuel pump by reversing the removal steps.

4. Check and Replace Fuel Filter (if applicable)

Locate the fuel filter along the fuel line.
Depressurize the fuel system by removing the fuel pump relay and cranking the engine briefly.
Disconnect fuel lines and remove the old filter.
Install a new fuel filter, ensuring proper orientation and secure connections.

5. Inspect EVAP System Components

Check the purge valve and make sure it's functioning properly; replace if defective.
Inspect the charcoal canister for cracks or damage and replace if necessary.
