EGR engine? You still need to remove the rocker cover. The coil resistance for the open or close coils is 0.7 to 1.5 ohms. Should be totally open to ground. If you measure outside the engine at the pass through connector, you still don't know if it is the pass through gasket or not. The electrical fault may be intermittent and only show up when the engine is hot too, so it may check good if you test it cold. 95% of the time, it is the injector. With engines this old, we highly recommend to replace all six injectors, the pass though under valve cover harness and ICP sensor while you have it apart. If not, 4 months from now, another one goes and you are right back to where you started.
