Fuel System Pressure Release

WARNING: This page is about a different car, the 2003 Dodge Dakota. However, it is still accessible from the selected car via links, so may be relevant.
WARNING: Always release fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
  1. Remove fuel cap from fuel tank. Remove fuel pump relay from Power Distribution Center (PDC). See Figure and Figure . Fuel pump relay can be identified by label on inside of PDC cover.
  2. Start engine and allow engine to idle until engine stalls. Attempt to restart engine until engine will no longer run. Turn ignition off. Service fuel system as necessary. After performing repairs, install fuel pump relay in PDC.
  3. If fuel injectors or fuel rails are to be serviced, disconnect electrical connector at any fuel injector. Connect jumper wire between one electrical terminal on fuel injector and positive battery terminal.
    CAUTION: DO NOT apply battery voltage to fuel injector for more than a few seconds or fuel injector may be damaged.
  4. Connect another jumper wire on remaining electrical terminal on fuel injector. Momentarily touch remaining end of jumper wire to negative battery terminal in short intervals to energize fuel injector and release remaining fuel pressure.
  5. Diagnostic Trouble Code (DTC) may have been stored in Powertrain Control Module (PCM) due to removal of fuel pump relay. Using scan tool, clear DTCs from PCM. See appropriate SELF-DIAGNOSTICS article for clearing of DTCs.
