Well if it isnt showing conver

Well if it isnt showing convergence info for k and epsilon, you are not solving for turbulence. Check your constant/turbulenceProperties dictionary. turbulence should be "on" and the turbulence model...

So what is your inlet value for k and epsilon?
Is the turbulence solver doing anything?

why did you edit the k file? Buoyancy has no effect on k and epsilon BCs. You should use fixedValue for k at the inlet.
You need wallBuoyantPressure for p at all boundaries where it is usually...

One thing I can tell you about buoyant calculations from painfull personal experience: make 100% sure all your wall and inlet pressure boundaries are defined as "wallBuoyantPressure" and not...
