need help fixing problem with some radiators on domestic system?

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.
