I don't think it's a hose issue or vent tube issue. Something electrical. Really surpised that changing out that relay didnt help the issue. If it was a hose issue the fuel pump would still try to prime and you'd still hear the whine noise from the fuel pump when you turn on the IGN. Gotta be something electrical not powering up the fuel pump. System Relay, fuse, wiring...
when the IGN is turned on the fuel pump should start(whine) for a few seconds while is pressurizing the discharge line to the injectors. if the bike is not started the whine will stop after a few seconds. so if the IGN was on and the pump was cycling on and off mulitple times that, to me, would indicate a discharge tube leak inside(or outside) the tank. But being that the pump is not making any noise at all when the IGN is turned on tells me that it's electrical.
unless i'm misinterperting what the OP is stating, which has been known to happen.
just my .02

The OP said he heard a hiss and bubbling noise when he turned on the IGN. Thats exactly what mine did a couple weeks ago before my indy found the crack in the vent tube. Along with hissing, I could hear a bubbling noise...same as OP. One thing that makes me think you could be right is my bike would still start but would pop thru the intake and ran very rough. Hopefully the OP will find out soon and let us know.
yeah man, let us know what you find out.
