Most likely cause of sudden no spark issue like that is a failed ignition coil or a blown fuse. Have you checked the fuses?

With a coil like yours, I use an in-line spark tester to see if there is anything coming out of the coil. Here is a link to the one that I use: https://www.amazon.com/Lisle-20610-Inline-Spark-Tester/dp/B0002STSC6/ref=sr_1_3?ie=UTF8&qid=1501325755&sr=8-3&keywords=spark+tester

AutoZone also carriers similar testers for a few bucks more than Amazon's price. If there is no spark coming out of there, then we have identified the problem. Let us know.
