Fuel Injector Resistance: SC400

Turn ignition off. Remove engine cover. Remove battery cover and air cleaner inlet tube. Remove intake air connector tube. Disconnect appropriate injector connector. Measure resistance between injector terminals. Resistance should be 13.4-14.2 ohms at 68°F (20°C). If resistance is not 13.4-14.2 ohms at 68°F (20°C), replace injector.
