Solution

1. Preparation

Gather required tools: OBD-II scanner, fuel pressure gauge, multimeter, socket set.
Disconnect the negative battery terminal to prevent electrical shock.
Relieve fuel system pressure by removing the fuel pump relay and starting the engine until it stalls.

2. Inspect and Replace Fuel Pump Relay

Locate the fuel pump relay (refer to the owner’s manual for the exact location).
Remove the relay using a socket set.
Test the relay with a multimeter for continuity.
If faulty, replace with a new relay of the same specifications.

3. Check and Replace Fuel Pump

Access the fuel pump by removing the rear seat or accessing the fuel tank from under the vehicle.
Disconnect the fuel lines and electrical connectors from the fuel pump.
Remove the fuel pump assembly from the tank (note the orientation for reinstallation).
Inspect the pump for any signs of damage or wear.
Install a new fuel pump if necessary, ensuring it is properly seated and secured.

4. Reassemble and Test

Reconnect the fuel lines and electrical connectors, ensuring a tight fit.
Reinstall the fuel pump assembly into the tank.
Reconnect the negative battery terminal.
Start the engine and monitor for proper operation and leaks.
