It depends on what you mean by no fire...
Do you mean no spark? or it just won't start?

Does the starter turn over?

Unplug the main wireing harness from the CDI. Turn the ignition to the ON position. Use a volt meter to find the 12v line going to the CDI. Turn the quad off. Plug the wiring back in. Turn it back to ON. Check the voltage on the same wire (from the backside of the plug). If you're getting like 1.5v then you have an oxidized connector on the wiring harness. Usually the monster plug under the tank in front of the engine. That thing is a pain to get unplugged.. lol.
