did you bleed them when you filled the system back up? Chances are they are full of air. Get a bleed key and tap off the air. then, if its a sealed system, check the pressure and fill if nessecary.

have been able to get one radiator going it was a sticking thermostat valve but the other rad seems to have a blockage in the pipe as it is cold going to the rad anyone any ideas?

Turn one valve off on all your other radiators and usually it will force the water around this rad getting rid of your airlock
