Solution
1. Preparation
  • Tools Required: OBD-II scanner, fuel pressure gauge, multimeter, socket set, vehicle service manual.
  • Safety Warning: Disconnect the battery before working on electrical systems and relieve fuel system pressure by removing the fuel pump fuse and starting the engine until it stalls.
2. Check Fuel Pressure
  • Sub-steps:
    1. Locate the fuel rail test port.
    2. Connect the fuel pressure gauge to the test port securely.
    3. Turn the ignition to the "ON" position and observe the pressure reading.
    4. Compare the reading to the BMW specifications (typically around 50-60 psi).
    5. If the pressure is below specifications, proceed to replace the fuel pump.
3. Replace Fuel Pump (if necessary)
  • Sub-steps:
    1. Disconnect the battery.
    2. Remove the rear seat or access panel to reach the fuel pump access.
