Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the negative battery terminal to ensure safety.
Ensure the vehicle is on a flat surface and properly supported with jack stands if necessary.

2. Fuel Pump Inspection

Remove the access panel for the fuel pump located under the rear seat.
Disconnect the electrical connector and fuel lines from the pump.
Use a multimeter to test the fuel pump for proper voltage when the ignition is turned on.
If the pump is faulty, replace it with a new one following the manufacturer's specifications.

3. Fuel Pressure Test

Connect a fuel pressure gauge to the fuel rail service port.
Turn the ignition to the ON position (do not start the engine) to check the fuel pressure reading.
Compare the reading to the manufacturer's specifications (usually around 40-50 psi).
If pressure is low, inspect the fuel filter for clogging and replace if necessary.

4. EVAP System Check

Inspect the EVAP canister and purge valve for any signs of blockage or damage.
Replace any defective components to ensure proper vapor recovery and fuel system operation.

5. Reassemble and Test

Reattach all connectors and lines securely.
Reinstall the fuel pump access panel.
Reconnect the negative battery terminal.
Start the engine to verify repair effectiveness.
