Before the ohm test start engine and check each injector with a long wood dowel placed on top of each injector cap. Listen for the very audible tick-tick-tick....... A dead injector will lack the tick, bad sign. The ohm test will be conclusive for the injector. 10 to 14 ohms is in spec but closer to 10 better. Also note if any corrosion in the electrical connector. Good idea to clean contacts and fill connector with dilectric grease. Do this to as many connectors as you can reach.
