Re: no spark on one cylinder
If the problem is in the pak, and all you have to work with is an ohm meter, try this test to further isolate the problem. Unplug the 6 wire connector between the timer base, and pak. Disconnect the black timer base ground lead. Connect the ohm meter black lead to timer base ground lead, don't let these lead's touch the block. With the ohm meter red lead, touch each of the 6 colored lead's coming from the timer base. With the meter on the Rx100 scale, the reading should be 40 ohms, + or - ten ohm's. Next attach the meter ground lead to a clean engine ground, again with the meter red lead touch each of the colored lead's coming from the timer base, you should get no reading. The ground lead from the timer base is left disconnected, and isolated during this test, What you are doing is checking the ignition trigger coil's. This is about as far as you can go with an ohm meter.
