High Pressure Residuals

I'm simulating a fully developed flow using pimplefoam (I've read that now includes the channelfoam solver) and cyclic BCs on inlet/outlet; but i'm facing a strange problem. I have a pressure's residual too high (about 1) and it doeasn't decrease.

Here what i've done:
-consider a finer mesh
-change fvsolution and schemes
-change Courant number (lowered to 0.5) and time step
-change initial values

The problem hasn't been solved and I don't know why. I've made the same setting long time ago and it worked unfortunately i lost that case files.
