We have a Bryant 310AAV/JAV furnace will start up, but will not heat. There is no flame, but you can smell gas. The codes are first 14 then 34. We are without heat and have no clue what to do. Please help

I have a Bryant furnace that is 7 years old. My heat went out on Dec.25,2010, I had a friend from the gas company come out and was told that I needed a thermostat and furnace ignition. I put the thermostat in myself which took 10 minutes, my wires on the thermostat was a 4 wire with red,green,white and blue which hooks up to Y for cold. Before you pay someone to check out your furnace look around first, I was told that to get my heat back on by a contractor that it would be $350.00. I had my friend come out and had to pay $50.00 for the ignition switch and $59.00 for a Honeywell thermostat.It only took 10 minutes to put the furnace ignition on.My furnace was blinking 3 blinks and then 1 blink.As soon as I turned the thermostat on to heat my flame then came on.Good luck.
