What are the usualy supsects?

Here is what I got --

1. Spark -- works fine. Tested each coil with a known good plug.
2. I have the air box off. I can see fuel coming into the engine.
3. Air -- I am not in outerspace.

I threw some starter fluid into each throttle body. Still nothing.

Does anyone have any other ideas?

 

Have you removed your right clutch cover case recently? I was installing a new engine cover(chrome) and put the cam pulse generator on backwards. It wouldn't start, you can take the plug off and look to see if the fins are making contact with the generator.

 

but did you actually take each spark plug out and check? its a bitch to do but i foweled all 4 of mine at one time...
