Fuel System Pressure Release

WARNING: This page is about a different variant/trim than selected.
WARNING: ALWAYS release fuel pressure before disconnecting any fuel injection-related component. DO NOT allow fuel to contact engine or electrical components.
CAUTION: When battery is disconnected, vehicle computer and memory systems may lose memory data. Driveability problems may exist until computer systems have completed a relearn cycle. See COMPUTER RELEARN PROCEDURES article in GENERAL INFORMATION before disconnecting battery.
  1. Disconnect electrical connector at injector. Connect jumper wire between Dark Green/Orange wire electrical terminal on injector and positive battery terminal.
  2. Momentarily connect jumper wire between remaining electrical terminal on injector and ground for no longer than 5 seconds. DO NOT exceed 5 seconds or injector may be damaged. This operates injector and releases fuel pressure.
  3. Wait 5 seconds and then ground jumper wire for another 5 seconds. Remove jumper wires. Install electrical connector. Fuel pressure should now be released. Use care when disconnecting fuel lines, as some fuel pressure may still exist in fuel lines.
