York Furnace (#PISPD16N0100IA) ignitors not lighting

I had a gas leak at my main gas line to my house, the utility company came out and replaced my gas meter. They came inside and relit pilots to water heater but not furnace. Now my furnace is not working. The pilot light, lights and stays on, but the burners do not light. The blower is running and i can hear a humming sound coming from a black fan motor inside the furnace.

Thanks for your help.

Was your furnace working real recently before the gas company fixed the main line? Or hadn't you ran it yet this year?

Check to make sure that the black fan (induced draft motor) is actually running not just humming. If it is running, the rubber hose connecting the blower to the pressure switch may be clogged. If the hose is plugged the pressure switch will not close and will not allow the gas valve to open to the burners.
