Fuel Injector Test

  1. Connect one end of jumper wire to a clean chassis ground and turn ignition switch to "RUN" position. Using jumper wire, ground Tan wire at injector. Listen and feel for injector click.
  2. If injector clicks, injector test is okay. Go to CONTROL CIRCUIT CONTINUITY TEST  . If injector does not click, use a test light and check for voltage at Red wire on injector. If voltage is present, replace injector and retest system. See Fig 1 .
