THANK YOU!!! I HAD BEEN THE IDIOT AND CLOSED THE FLOW RETURN VALVE. OPENED NOW IT SEEMS TO BOOTED INTO LIFE.

Air vent cap has little screwed in stopper on top that is half screwed in.
Pump is not on but presume this is becuase the temperature guage still says its over 75 and this is the cut out temp

Update - no hot water or heating, reset boiler but as...
