Fuel System Pressure Release

WARNING: Fuel system is under high pressure. Release fuel pressure before disconnecting any fuel lines or fuel system components.
  1. Turn ignition off. Remove fuel pump relay from Power Distribution Center (PDC). PDC is located in engine compartment. Start engine and let it idle until engine stalls. Attempt restarting engine until engine will no longer run. Turn ignition off. Remove fuel tank filler cap from fuel tank to release any pressure from fuel tank.
  2. Fuel system components may now be serviced. Use care when servicing fuel system components, as some fuel pressure may still exist in the fuel system. Install fuel tank filler cap and fuel pump relay once fuel system components are serviced.
  3. Diagnostic Trouble Code (DTC) may have been stored in PCM due to the removal of fuel pump relay. Clear DTCs from PCM. Using scan tool, clear DTCs.
