Question bryant plus 90 fan on but no coil lit 12yr old

i have a bryant plus 90 model #350mav048100 does anyone know what could be wrong the blower starts and stops clicks when heat is called but the coil wont lite i have made sure the gas is on and the valve is opened i lived in the house for 8yr never a problem i have shut the furnace down and started over also i went outside and cleared out the exhast pvc at the house so there is nothing clogging or restricting the air flow. if any solution please state where i can purchase parts thanks . EAST AMHERST NY 14051 could this be the board or the mechanicsim that has the gas on off looks like it is about 5inches long and maybe 3 wide with threaded gas going in and 1 going out. and if it is the board am i better off with a new furnace maybe one more efficient with the advances in technology?

When you say that the blower "starts and stops", are you talking about the vent inducer blower or the air blower? What kind of ignition is there? Electronic spark or Hot surface ignitor?
