First you need to unplug the two plugs coming out of the stator, you will see one with three prong holes: that's for the source coil and the other has four that is where you check your pickup coil, depending on what year you have, there will be two coils on the early years 87- maybe up to 90 or 92, after that just a single onward. The color coding on the wires you will have to get out of a Yamaha factory manual, to figure out which coil is bad, the Clymer manual won't show you the color to each coil.

1999 Alero how do i test ignition coil pack
if you have the module off take it to a parts store(autozone/advanced auto,or whatever you have around your location) they should be able to test it for free. you may also want to check your pick up coil/coil and distributer.
to save time and money the best way to find the problem is to have diagnostic test done this way here you want have any doubts if you remove the module (not too hard). autozone and other places like that can test it for you for free. if its good then you know to replace the pick up coil. if its bad then you know to replace the module. you can aslo test the coil with a multimeter but i would guess that you dont have one and this would be a lot more work... I like to pull a known good module from another truck, I have had gm modules pass the bench test that were actually bad, so you end up chasing your tail looking for other problems when there are none.
Take off the modual and coil pack take it to autozone they will test it free.
