It sounds like you have done a fair amount of checking. That's a good start.
What is the condition of the plugs? I have worked on hondas where the spark plugs seem to suddenly spark their last spark. If you pull them and they look burned out and the electrode gap is way over then that's a good place to start.
The best way to test the injectors is with a noid light set on the injector harness. You plug it in in place of the injector on each injector connector and see if the light blinks when you crank the key.
You should also check the fuel injector relay. The PGM-FI main relay is located under the driver's side of the dash, right of the steering column. Always verify powers and grounds to the PGM-FI main relay.
