Do you have a manual? If you do can you send me a copy of the correct schematic for your bike. It will me help you if you can scan a copy in to send me. If you don't already have a basic voltmeter that measures resistance. You should pick one up at either WalMart or even better Harbor Freight has the best deal $4-$9 there. What year is your bike? You can start off by isolating the kill switches from the coil by unplugging the coil lead headed towards on/off switch and other safety switches. The idea here is to make sure you don't have a bad switch by disconnecting all kill switches to test for spark. If still no spark does the bike have cdi box or points fire ignition. CDI is capacitor discharge ignition often refered to as the black box. Points are mechanical switches that open and close riding on the crankshaft.
Please send year of bike so I can better assist you.
Thank you,

Why no spark

There should be three coils mounted on the ignition module.
Each coil fires two plugs, one positive and one negative.
If one of the three coils is dead, it could be the coil. If every other plug is not firing, it could be the module.

Motorcycles Not getting spark from back 2 plugs

Sounds like you have power to the coil, but the coil is faulty and not producing a spark.

Remove the coils. Put power to it, you should get a spark when you remove the negative lead.

Im getting fire from the coil to the cap but

Check the wire itself by placing it in a different position in the cap. If it's OK, check the inside of the cap for any carbon tracking especially near the #1 wire tower. You have spark from all other wires? It sounds like you have a bad cap. but check both.

Coils won't fire 12 volts both sides what grounds them so they will fire

im not familliar with this bike, but it sounds like the coils are powered from the positive battery, and the igniter module provides the ground signal to fire the coils. check ignition fuse and then check igniter module. maybe this may help.
