You have fuel spray, you have spark at the coil. That doesn't mean you have spark ACROSS THE PLUG GAP where the spark does some good, and AT THE RIGHT TIME.

Check cap, rotor, plug wires, and if they're good...verify that the plugs aren't fouled or excessively worn.
Wouldn't hurt to find out if the gasoline is so old it won't burn. Not likely, but possible.

It's unlikely that you've lost compression, or plugged the exhaust--and if you have a burnable fuel/air mix, spark across the plug gap at the right time, compression and a non-restricted exhaust...the engine ought to run.
