Solution
1. Preparation
  • Gather necessary tools and parts.
  • Ensure the vehicle is on a flat surface and the ignition is off.
  • Disconnect the battery negative terminal for safety.
2. Inspect Fuel System
  • Fuel Cap: Check the fuel cap for proper sealing. If damaged, replace it.
  • Fuel Lines: Visually inspect all fuel lines for cracks or leaks. Replace any damaged lines.
3. Test and Replace Fuel Pump
  • Fuel Pressure Testing: Connect a fuel pressure gauge to the fuel rail. Turn the ignition to the "ON" position without starting. Check the pressure reading; it should be within the manufacturer’s specifications (typically around 50-60 psi).
    • If pressure is low:
      • Remove Fuel Pump: Access the fuel pump by removing the rear seat or trunk panel as needed. Disconnect the electrical connector and fuel lines.
      • Replace Fuel Pump: Install the new fuel pump, reconnect fuel lines and electrical connectors. Ensure all connections are secure.
4. Reconnect Battery and Test
  • Reconnect the battery negative terminal.
  • Attempt to start the engine.
