    Help me troubleshoot ignition system please

    Hell, let me get into it right away. My car is cranking but not starting. After a lot of inspection I came to conclusion that problem is related to spark plugs not getting the spark. Now, I want to test my ignition coil first, and the pickup/igniter module that was suposed to switch the ignition coil on and off. Please, how to test those components?

    The car is 1990 Mazda 323 sedan. It's not an US model, so it's not labeled "protege", but I guess it has to be the same car. Engine in it is a Mazda B3, to be precise a 1324cc, 16 valve engine with a carburetor.

    Ignition coil wise, I know that I should test the resistance in the primary and secondary coil for correct values. The problem is in the next situation.....every god-damn service manual I came across shows an ignition coil with just three wires connected to it: two low tension wires (battery + and ground) and one high tension lead that conducts spart to the distributor cap.

    Notice both black connector on the left, and white connector to the right. Please, tell me some info about signal path in this case. So far I figured out that 12 volts from the battery go from one wire on the left black connector, when the key is switched on. White conncector has two wires that go to the igniter module in the distributor. Please, how to test this coil, which points should I measure???

      UPDATE. Car is fixed and is running fine. The problem was bad ignition module which I replaced. Glad I could fix this for cheap.
