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. See CLEARING DIAGNOSTIC TROUBLE CODES under SELF-DIAGNOSTIC SYSTEM.
