Default No fire to plug on 99 Big Bear

My 1999 Big Bear will not start. It was running fine then the battery went dead. Bought a new battery. Turns over just fine but won't fire the plug. I could not find the problem so I took it to a mechanic. He said he checked the coil and everything else, and was 99% sure it was the CDI. I said are you sure, because the way it just quit firing the plug, it didn't sound like it was the CDI. He was wrong. I put a new one... $$$! Plus the cost of the mechanic! Still the same problem. Let me reemphasize something, it will turn over fine. Also I put a new starter solenoid on it because one of the wires fell off of it. I forgot too much about these things and need some help, haven't had one in years. Will probably have to trace the wires to the coil and figure out why it is not getting power.

I just changed the ignition coil on a Big Bear and it solved the same problem, quick cheap fix. Always start at the cheap stuff before moving to the more expensive stuff like Stators and CID boxes.

Changed the Ignition Coil. Still won't run. Turns over but no fire to plug. So far New CDI, Starter Solenoid and Ignition Coil. Are there any switches that let it turn over and not fire? I would think that any safety switches would not even let it turn over.

Did you change the plug?. They can fail too, you know. Check all kill switches, ignition and brake light switches, anything that can kill spark. How about stator keyway and stator ignition pulse pickup, do they check out OK?.
