Check the ballvalve/filling loop is passing an adequate amount of water into the system.

If the bottom rads have filled up; but you cannot get upstairs to fill; try running the pump to agitate the water and free any air - Check your airing cupboard (If you have one) for air legs on any key flow and a return pipes.

If no rads are filling up; it's likely you have a blocked or partially blocked cold feed - Plumber requried.
