Solution

1. Preparation

Gather tools: OBD-II scanner, multimeter, fuel pressure gauge, basic hand tools (screwdrivers, socket set).
Ensure the vehicle is parked on a level surface and the engine is cool.

2. Access the Fuel Pump

Remove rear seats: If necessary, remove the rear seats to access the fuel pump access panel.
Remove access panel: Unscrew the panel covering the fuel pump located under the rear seats or in the trunk area.

3. Inspect Fuel Pump Wiring

Check connections: Disconnect the electrical connector from the fuel pump and inspect for corrosion or damage.
Test voltage: Use a multimeter to check for voltage at the connector while the ignition is in the "on" position; it should read approximately 12 volts.

4. Replace Fuel Pump (if necessary)

Disconnect fuel lines: Safely relieve fuel system pressure by removing the fuel pump fuse and cranking the engine until it stalls. Then, disconnect fuel lines from the pump.
Remove the pump: Unscrew and carefully lift out the fuel pump assembly from the tank, taking care to avoid damaging any components.
Install new pump: Place the new pump into the housing, ensuring it is securely fitted, and reconnect the fuel lines.
Reassemble: Replace the access panel and re-install the rear seats.
