Solution

1. Preparation

Gather tools and parts.
Ensure the vehicle is in a well-ventilated area.
Disconnect the battery to prevent electrical shorts.

2. Inspect Fuel Pump Fuse and Relay

Locate the fuse box (typically under the dashboard or in the engine bay).
Remove the fuel pump fuse and inspect for damage; replace if necessary.
Test the fuel pump relay by swapping it with a similar relay in the fuse box.

3. Test Fuel Pressure

Connect a fuel pressure gauge to the fuel rail Schrader valve.
Turn the ignition to the "ON" position without starting the engine; check if the gauge indicates the correct pressure (consult service manual for specifications).
If pressure is low, proceed to check the fuel pump.

4. Verify Fuel Pump Operation

Reconnect the battery and turn the ignition key to the "ON" position.
Listen for the fuel pump activation sound (a humming noise) for a few seconds.
If no sound is heard, check the electrical connector to the pump for corrosion or loose connections.

5. Inspect Fuel Filler Cap and Lines

Remove the fuel filler cap; inspect the rubber seal for wear or damage.
Check the fuel lines for cracks or leaks from the tank to the engine.
