Fuel System Pressure Release
CAUTION:
Always release fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
- Locate Power Distribution Center (PDC) on left side of engine compartment. See Figure. Remove fuel pump relay from PDC. See Fig 1.
- Start engine and allow engine to idle until engine stalls. Attempt to restart engine until engine will no longer run. Turn ignition off. 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.
- Diagnostic Trouble Code (DTC) may have been stored in Powertrain Control Module (PCM) due to the removal of fuel pump relay. Using scan tool, clear DTCs from PCM.
