  1. Using a stethoscope, check operating sound of injector(s) during engine cranking or idling. If clicking sound is heard, injectors are okay. If clicking sound is not heard at each injector, go to step 2).
  2. Disconnect injector electrical connector. Measure resistance between injector connector terminals. At 68°F (20°C), if resistance is not 13-16 ohms (2-3 ohms on turbo models), replace injector.
  3. If resistance is within specification, check injector wiring circuit for open or short to ground. If wiring circuit tests okay, replace injector.
