Q: No spark at spark plugs

A: I will assume that the results of the test ...

I will assume that the results of the test were taken from the location between the spark plug boot, and the top of the spark plug. In this case, the spark is not getting to the wire at all, or it's escaping the wire through a break, and reaching ground before going through the combustion chamber. The lack of spark may have caused the spark plugs to foul, so do not forget about them. Have an experienced mechanic, with the proper equipment, test your ignition system for signs of wear or a failure.
