To do it by fuel pressure a sophisticated fuel pressure tester will have the adapters for Hondas. It attaches to the fuel filter. You could remove the fuel rail and crank the engine with the injectors squirting into little jars or bottles and watch the pattern. And turn the key on and see if any drip without cranking.
Edit: also check to see if any part numbers are on the injectors and run them
