    There's only one coil on your car.

    Is there anyway to test the plug in that goes into the module to see if I am getting any juice to the module if not should I just replace the icm and coils

    Bench testing ICMs and coils is not reliable. Too often they test fine but don't work at all. I would install a new ICM and two new coil packs, if that's what you have. The AutoZone site shows only one coil for your engine and a coil pack housing. I recommend replacing ICMs and coils every 120,000 or 10 years, whichever comes first.

    Is there any way I can test the end of the plug that goes into the module to see if there is juice going to the module

    I'm not familiar enough with your car to say. You should consult a Haynes Manual, if you want to do that.

    The motor "jumps"?
    Has anyone checked to see if the engine is perhaps seized?

    You need a Haynes Manual on your car and see what tests they recommend that we have not performed. I'm not that familiar with your car to get more specific than I have. Ensure all under dash and under hood fuses test OK with the test light or multimeter. Make sure you get the sense that the PCM (computer) is working.

    Make sure your've performed the tests in the link below:

    Sorry I can't offer more help.

    Please, read post # 49 on this thread.
    You won't have spark via the Crank Position Sensor (CPS) if the engine doesn't turn.
    Can you move the engine through an entire 360° revolution? As in: no mechanical damage internally?

    Thought:

    The anti-theft system may be preventing the car from starting. It would likely take the dealer to solve, if this is the situation.

    Correct-a-mundo!

    You'll need someone locally with the tools and talents to finish this diagnosis.
    Then, all the bits and pieces will come together.

    How do I test to find out if it is the anti theft system would that also cause it not to have spark
