The pump is ok (have removed and checked & only 3 months old),
and if i push the (2 port Honeywell)

Before we go any further, bleed all of your radiators and any bleed valves
you see elsewhere on the pipework, such as near the pump, boiler and zone
valves.

The symptoms seem to indicate that no water is flowing. How are you sure the
pump is working? Don't be distracted by the fact that the pump is new. The
"bathtub" reliability curve indicates that brand new equipment is less
reliable than stuff that has been installed and working for a couple of
years.
