Fuel Injector Flow

  1. Remove fuel injectors with fuel rail. See FUEL INJECTORS in REMOVAL, OVERHAUL & INSTALLATION article. Leave injectors connected to fuel rail. Fit a transparent hose about 15" long and 9/16" inside diameter onto end of injector. Place end of hose into a suitable container. Reconnect fuel injector electrical connectors. Connect a jumper wire between the following fuse terminals: on 9-3, between fuse No. 4 upper terminal and fuse No. 32 lower terminal. On 9-5, between fuse No. 8 upper terminal and fuse No. 19 lower terminal.
  2. Use scan tool to perform injector flow test. Scan tool should continue test for 30 seconds. Measure volume of fuel for each injector. See appropriate FUEL INJECTOR FLOW SPECIFICATIONS  table. Repair or replace any injector that does not meet specifications.
