Hi,
Is it possible for you to record it from under the hood so I can better hear the engine cranking? I could hardly hear anything. If you have a helper, have them crank it while you stand in front of the vehicle with the hood open.
I really need to hear it because if you have spark at the plugs, fuel to the engine, and compression, it should run, unless the timing is off. I should be able to tell by listening to it cranking, I just need to hear it a bit better.
Also, the idea that starting fluid made no difference makes me think there is no spark (if the timing is correct). I/m not sure how you tested it, but here is a link showing how to do it. Take a look through it and see if it's what you did.

Also, where are you feeling air come out of the valves? And yes, the timing belt could have jumped time.
Let me know.
