Fuel Pump Issue

Nope, it doesn't kick on at all until the bike is running. You have to prime the pump, (so to speak) by creating a jumper between 2 female points on it's plug with the key in the on position. It even tells you how to do it in the service manual.
Edit - I am only referring to the way a f3 pump works. I believe other generations may operate differently, but not totally sure about that.

That's insane. So, if the bike runs out of gas and you're not versed on how to do this thing you describe, you're screwed. It can't actually work that way, it makes no sense. Bikes are run dry all the time...intentionally and by mistake. Having to dig into the wiring whenever you ran the bowls dry would be a serious shortcoming, and Honda is simply smarter than that.
Apologies if it seems that I'm being contrary, but there has to be SOME method of getting gas to the card bowls without the engine running - either through some gravitational method through the pump, or by the pump priming when the key is turned or vacuum is sensed from cranking the engine. I do not have the manual for the F3, but may download it to investigate.

Not taking it that you're being contrary, not at all.
The bike will run on gravity. There's some debate on how well or if it should, but it does run on gravity. I've gotten my bike to start from dry like that. It does take a lot more cranking. I may have been unintentionally misleading when I said you "have" to prime the pump. I've just done it that way for so long so as not to potentially drain my battery by cranking it, that I automatically do it when the need arises.
.
In the service manual, the process to perform what I described is in section 18, pages 16-17.
If the OP follows those steps, it will tell him if his fuel pump is GTG or not.

It's common for people to put a meter on the 2 wires going to the fuel pump expecting to see 12v when they turn the key on. That doesn't happen. Also, even when the engine is running, measuring those same wires won't show a continuous 12v. That's because the relay is providing a "pulsed" supply. You'd need to have a meter that can capture "Peak" voltage. Then you'll see the 12v.
