Inside your furnace you will see clear plastic tubes running to a pressure switch, make sure these tubes are in fine condition. Check the pressure switch for correct operation by bypassing the pressure switch and ruining the unit. If the unit runs with the switch bypassed you have found your issue.

Do you know where the pressure switch is located? If so remove the 2 wires that are attached to it and touch the wires together. Then try to start it and see what it does.
