IIRC; the pilot light flame heats a sensor which energises the solenoid in the gas manifold valve and permits gas to flow to the main burners. [The gas manifold is a multi-port device which sequentially admits gas; - after the boiler is pressurised (by the fan) to the pilot light; then after the pilot light has operated to the main burner(s)]. Is the exteernal vent get-at-able? Can you smell gas being admitted to the burners? Is the main burner gas solenoid u/s?
