No spark

2010 rzr 4, and it has no spark. I started it Saturday and moved it. Yesterday i went out to move it and it wouldn’t start. I can hear the fuel pump, so its getting fuel. While i was letting it spin over, it would eventualy backfire. It did this a few times and now it just spins and not backfires. I pulled the plug and no spark. Could it be the CDI box and if it is where is it located. I checked the fuses up under the dash by the steering wheel. Any input.
