It may be that the draft inducer fan motor is bad or the pressure switch is bad.
To determine which is causing the problem you will need to call your HVAC tech. There are some DIY forums that provide advice for how to check bot, but if you are unfamiliar with working on furnaces it is highly recommended you not try to diagnose and fix it on your own.
To keep legal happy, let me just say that I am not an HVAC contractor, and you should never even look at your furnace without having a qualified, liability accepting HVAC contractor present.
