1992 Acura Integra 92 Acura Integra won't start

I have a 92 Integra that won't start. I'm getting a good spark to the plugs and I'm getting fuel to the fuel rail. I don't have any check engine lights that come on. It ran great and just wouldn't start up the next day. The timing is on and the belt is good and not missing any teeth. I tried using starting fluid and that didn't work. It almost fires but just won't fully do it. What can it be? I'm totally stumped. Any advice would be greatly appreciated. Thank you.
