turn radiators valves off at the radiators thats already working then open the rest of radiator valves that arent working, if that works leave them on for about 2 hours then open the rest of the radoators , plus check the pump while the boiler is on. it has a screw in the middle undo that with flat screw driver or chisel, a couple drips water will come out put not to worry thats just normal, once u undo that screw stick screw driver in u should feel if pump if its working.
