Guess I was going by the title of the thread, and your attempt to check continuity Bentley-style, knowing that won't apply to the 940.

Be sure that power you see at the injectors is present during your cranking attempts. If the plugs are still dry, make sure you are getting spark to at least two plugs. I'm not a 7/9 guy, but I have read a lot of posts here, and recall one trouble where the wire bringing the engine timing signal from the ICU to the ECU was pinched, so the ECU never really knew the motor was turning. This, I think, was a consequence of some under-the-dash work.

Anyway, no, you won't get continuity 9-18 through the injectors and ballast, because the RSR is not energized (hopefully) while you are using an ohmmeter on things. A squirt of starting fluid might be a quicker way to verify spark...
