It might be what Honda calls the fuel pump relay which is actually the fuel pump resistor by-pass relay. The relay is located on the inside firewall just behind the driver's side seat next to the traction control unit, probably between your spine and where your right shoulder is. The relay starts out unenergized and as the engine load increases the relay energizes (which might be click you here) to by-pass the fuel pump resistor and increase the fuel pump speed to insure sufficient fuel delivery.If you want to confirm that it is the fuel pump relay you could remove the inner bulk head cover to expose the relay which should make it easy to confirm that it is the relay making the click by listening while you drive. Relays normally make a noise when they operate; but, I don't know why you are all of a sudden hearing it unless it is just a matter of becoming aware of it and now you are listening for it. I have never noticed mine.If you want to replace it, I think it is a Denso 056700-7330. Less than $20 new from Rock Auto.
