Honda fuel injectors are also known to be noisy. Fuel injectors by their design create a "ticking" sound and this was a common complaint among customers while I was at a Honda and Acura dealership. Sometimes cleaning out the fuel rail lessens the noise or replacing the noisy injector. This is noise is more prevalent when the engine is cold. This is not a sign of a bad or failing injector, just a noisy one. You can always remove the intake manifold cover when the engine is cold, start it and see if the noise is coming from an injector(s).
