Bleed the pump
Check for a vent on the cylinder primaries
Check that the header tank has water in it and that it feeds the system when you drain some water off (?blockages)
Bleed all the rads repeatedly until no air or foam comes out.
Close off most of the rads so you force air into the one(s) which is/are open
Check that the motorised valve(s) is/are on Man
Tell us what your system is
Tell us what your boiler is
And have you looked for a reset button on the boiler?
