Fuel Injector Resistance: LS400

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