You don't get spark to the coil. You get spark FROM the coil. The coil is the part that creates the high voltage spark.

I gave you pictures of it. It's designed for testing the signals without burning out the computer in the process. Most auto parts stores sell them.

Now what?

You haven't even followed the first instruction I gave you. I never advised you to throw parts at it.
