Fuel System Pressure Release: Gasoline

  1. Remove fuel tank cap. Remove Fuel Pump Relay from Power Distribution Center (PDC). PDC is located in left side of engine compartment. Start engine. Allow engine to run until engine stalls. Attempt to start engine until it will no longer run. Turn ignition off.
    2. CAUTION: Ensure step  1 is performed to release high-fuel pressure in the fuel rail before proceeding. DO NOT attempt to use the following steps to release fuel pressure unless step  1 has been performed, as excessive fuel will be released into the cylinder.
  2. Disconnect any fuel injector harness connector. Connect a jumper wire between one terminal of fuel injector (component side) and positive battery terminal.
  3. Momentarily connect another jumper wire between remaining electrical terminal at fuel injector (component side) and negative battery terminal for a few seconds. DO NOT apply voltage to fuel injector for extended time or fuel injector may be damaged. This operates fuel injector and releases fuel pressure.
  4. Remove jumper wires. Install fuel injector harness connector. Fuel pressure should now be released. Reinstall Fuel Pump Relay. Diagnostic Trouble Code (DTC) may have been stored in Powertrain Control Module (PCM) due to the removal of Fuel Pump Relay. For clearing DTC from PCM, see CLEARING DIAGNOSTIC TROUBLE CODES  under SELF-DIAGNOSTIC SYSTEM.
