Super Jet superjet wont start

Ive got a 95 superjet that wont start nor do i hear anything at all. It worked perfect last week when i used it. The following things are what i think may be the problem:

Lanyard? Dont know how to check/test it. It simply doesnt start
Bad start/stop switch? Dont know how to test
Battery? Its showing 12.18V, seems a little low but pretty sure its got less then 5hrs on it
Bad wires? The inside is nearly mint with no corrosion, rust or sludge on any of the connestions
Something in the electronic box? Ive got an volt meter so i can test whatever (starer relay?)
Starter? I bench tested it and it turned but sparked like crazy, not sure if i did it right but it spun
Spark plugs/wires? No corrosion and plugs look good

Forgot to mention i checked plugs and they look good. Pistons look good as well, motor turns freely by hand so its not seized.


Not sure what it coukd be. I didnt check everything above, but if i can get some help testing parts and how, id appreciate it. Thank you

Disconnect the black and white plugs for the start stop switch. They are located behind the pto carb near the e-box. Plug the black one into the white but not all the way. Just enough to make contact before the clips lock the plugs together. This will test out your start button and circuit for bad connections. It that doesn't work you can also jump out the two terminals on the box side of the white plug with a piece of wire to test out the solenoid.

Clean the connections on your battery as well.

Those are the only things you can do before pulling the ebox and inspecting inside.
 
Update: the start stop switch was faulty and im in the mist of replacing it. Before that, i took apart the exhaust, carbs and starter to find out what the problem was. When i try to start it, it keeps clunking sort of abnormally and doesnt start. New spark plugs. When i try to start it without plugs, it freely spins and doesnt make any noise. Fuel or spark problem?
 
I tried squirting some gas down the cylinders and it started right up...i forgot that when i cleaned the carbs, i completely drained the carbs of gas and it wasnt priming gas into engine due to air i believe. I ended up fixing my own question again! Thanks for the help and suggestions everyone, hope i can start enjoying some weekly rides.
