Did you turn the gas valve knob from pilot to "ON"?

May just be that the thermocouple is too weak to open the main valve.

A bad circ, or air in the boiler/piping would not prevent the burner from working. It would just cause the boiler to reach its set te,p quicker. And still have no heat.

A dirty pilot could cause it.

Corrosion on teh thermocouple could cause it also.
