99 wont start

Crv with b20 engine has me stumped. It does crank over and their is fire at the spark plugs, also fire at the coil but it still will not start. The ignition switch seems fine correct lights come on according to key position. I also tried spraying starting fluid down the intake and still will not start. I checked the timing belt and nothin is broke, it is correctly aligned. I am totally stumped on this problem, the ignitor seems to be fine too. Help any suggestions.

Anybody have an idea?
