Solution

1. Preparation

Tools Required: OBD-II scanner, fuel pressure gauge, multimeter, socket set, safety glasses, gloves.
Ensure the vehicle is parked on a flat surface, and the engine is cool.
Disconnect the battery negative terminal to prevent electrical shock.

2. Check Fuel Pump Relay

Open the fuse box and locate the fuel pump relay.
Remove the relay and use a multimeter to test for continuity.
- Sub-step: If there is no continuity, replace the relay.

3. Measure Fuel Pressure

Connect the fuel pressure gauge to the service port on the fuel rail.
Turn the ignition to the "ON" position and observe the pressure reading.
- Sub-step: Refer to the vehicle service manual for the specified fuel pressure range (typically around 50-60 psi).
- Sub-step: If pressure is low, the fuel pump may need replacement.

4. Test Fuel Pump Operation

Reconnect the battery and turn the ignition to the "ON" position.
Listen for a humming sound from the fuel tank area, which indicates the pump is running.
- Sub-step: If no sound is heard, the fuel pump may be defective and should be replaced.

5. Inspect Wiring and Connections

Visually check the wiring harness connected to the fuel pump for any signs of fraying or corrosion.
Repair or replace any damaged wiring as necessary.
