The engine turns over but there is no spark. There are 12 volts going to the coil and a good ground but nothing coming through on the primary wires when the engine is turning.

I have seen this problem before, we had to change the MAF sensor to fix it. Here is the location of the crankshaft angle sensor so you can check the connections for corrosion. Also, this video might help as well:

If this sensor has failed all you need to do is to unplug it and the engine should start and if so, replace the sensor. If this doesn't not work, please upload as short video of the engine cranking over so I can hear it. That way I can tell if the engine is hurt or not. Check out the images (below). Please upload pictures or videos in your response of any problems so we can see what to help you with.
