TSB : Fuel Injector Operation

Details

Remove engine cover. Using a stethoscope, listen for clicking from each injector (or feel injector for vibration using a screwdriver) with engine running or cranking. If clicking is not heard, check for loose connection at fuel injector connector or fuel injector resistance. See FUEL INJECTOR RESISTANCE . If fuel injector is okay, check for no voltage signal at suspect injector connector.
