A model number may help. Also, are you refering to the inducer fan?
If so, jump out the pressure switch. If it runs, start looking for a blockage in the combustion chamber, blockage in the line to the pressure switch, a bad inducer fan (not getting enough pressure to close switch) or a bad pressure switch.
