Fuel System Pressure Release

WARNING: Always release fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
  1. Turn ignition off. Remove fuel pump relay from Power Distribution Center (PDC). See Fig 1. PDC is located in engine compartment. See Fig 2.
  2. Start engine and allow engine to idle until engine stalls. Attempt restarting engine until engine will no longer run. Turn ignition off.
  3. Place a shop towel under fuel line quick-connector at fuel rail. Use care when disconnecting fuel lines, as some fuel pressure may still exist in fuel lines. Disconnect fuel line quick-connector. Reinstall fuel pump relay in PDC.
  4. One or more Diagnostic Trouble Codes (DTC) may set when fuel pump relay is removed. Using scan tool, erase any DTCs that may have set after fuel pressure release procedure.
