Furnace not circulating

I need some help!
I had a radiator pipe break under the house and all the water from the radiators drained out.
I replaced the broken pipe and the radiators are filled back up.
Now when I turn on the heat the water won't circulate.
It was fine until the pipe broke. I have a combo furnace and I'm getting hot water to the sinks but the circulator pump won't turn on to get heat.
The circulator pump was working fine and will turn on if I push in the relay.

Are you saying water will not flow because the system is air bound or because the pump will not run. The pump not running has nothing to do with the pipe break unless the water got into the electrical circuit.

More info is needed like what do you have for controls and did you bleed the system after you filled it back up. Pics would be very helpful of the boiler and controls.

I'm sure it has something to do with the system being air bound, everything was fine until the pipe break.
i only bled the radiators, what else should be bled?
I have a 1980 new yorker combo furnace.
