To check from spark you can go old school and pull the plug and watch for spark. Plenty of videos out there with more specifics.

Another option is to buy a $10 tool light that slips between spark plug and coil. It will flash consistent with firing if it is sparking. I always used the "old school" method, but finally broke down and bought the tool. One of my better tool purchases especially for the price.

Here is a video for a leaf blower:

It looks pretty much like the same one I have, and the process of use is the same as the video.
