Solution

1. Preparation

Gather tools and parts required for the repair.
Disconnect the battery to prevent electrical shorts during repairs.

2. Inspect and Replace Fuel Pump Relay

Tools Required: Socket set, multimeter.
Locate the fuel pump relay in the fuse box.
Test the relay with a multimeter for continuity; if faulty, replace it with a new one.

3. Check and Replace Fuel Pump (if necessary)

Tools Required: Fuel line disconnect tool, socket set, torque wrench.
Relieve fuel pressure by removing the fuel pump fuse and starting the engine until it stalls.
Disconnect the battery again for safety.
Remove the rear seat or access panel to access the fuel pump assembly.
Disconnect the electrical connectors and fuel lines from the fuel pump.
Remove the fuel pump assembly from the tank, noting the orientation.
Install the new fuel pump into the assembly, ensuring proper seals and connections.
Reinstall the assembly into the tank, reconnect lines, and electrical connectors.
Reconnect the battery and the fuel pump fuse.

4. Verify Fuel Pressure

Tools Required: Fuel pressure gauge.
Connect the fuel pressure gauge to the fuel rail.
Turn the ignition to the "On" position (without starting) to check pressure. It should meet specifications set by the manufacturer.
