Fuel Injectors

  1. Warm engine to normal operating temperature and operate at idle. Using stethoscope, listen for normal clicking sound at each injector during idle and acceleration. If clicking sound is not heard, check injector wiring circuit, or PCM power relay andcircuit.
  2. To check injector resistance, disconnect injector connectors. Using ohmmeter, measure resistance between injector terminals. Resistance should be 11-18 ohms at 68°F (20°C). If resistance is not as specified, replace injector.
