Fuel Injector Test
- 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.
- 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 .
