Solution
1. Preparation
  • Tools Required: OBD-II scanner, multimeter, socket set, fuel pressure gauge.
  • Ensure the vehicle is in park or neutral and the parking brake is engaged.
2. Battery and Connections
  1. Disconnect the Negative Terminal:
    • Use a socket set to remove the negative battery terminal.
  2. Clean Battery Terminals:
    • Inspect and clean both battery terminals and cable ends using a wire brush.
  3. Reconnect the Battery:
    • Reattach the negative terminal securely.
3. Fuel Pump Relay Check
  1. Locate the Relay:
    • Refer to the owner's manual to find the fuel pump relay in the fuse box.
  2. Swap the Relay:
    • Remove the fuel pump relay and replace it with a similar relay from the fuse box.
  3. Test the Fuel Pump:
    • Turn the ignition key to the "ON" position and listen for the fuel pump activation.
4. Fuel Pressure Test
  1. Prepare the Fuel Pressure Gauge:
    • Connect the fuel pressure gauge to the Schrader valve on the fuel rail.
  2. Turn the Ignition On:
    • Without starting the engine, turn the ignition key to "ON" and check the gauge reading.
    • The pressure should typically be between 50-60 psi.
  3. Release the Pressure:
    • Carefully release the pressure and disconnect the gauge after the test.
5. Ignition System Inspection
  1. Remove Spark Plug Wires:
    • Use a socket set to remove the spark plugs and inspect them for wear or fouling.
  2. Check Ignition Coils:
    • Test each ignition coil with a multimeter to ensure proper resistance values (typically 0.5-1.5 ohms).
  3. Reinstall Components:
    • Replace any faulty spark plugs or coils before reassembling.
