What is the problem ? The best to test everything, You need a DVA adaptor and a good multimeter.

if only one cylinder do not fire, they are some test you can do without special equipment, but a DVA is the best.

Or try a know good one switch-box.

There are several you tube sites. After reading in your repair manual about testing, check out a you tube site which will help understand what you have read.
