Please help. Igniter glows, i hear click but no flames 80% of the time

This is a reoccurring issue which i did not resolve last winter and now that the season has come again to use my heat ....here i am again frustrated as all hell. Ive tried my hardest to research the internet looking for a common fix to my prob. but have yet to find resolve. I am experiencing a successful chain of events until the final act of igniting the flames nothing happens most of the time. If i go in my basement and bang the hell out of the thing and restart it a bunch of times it usually will begin to work again for a few hours... maybe even a day. but then before i know it my house is cold again and my burners will not ignite untill i beat the **** out of it again or restart it a million times. :mad: :wall: can anyone please help? does this sound familiar to anybody?? i will post my specific furnace info if needed THANK YOU SO MUCH IN ADVANCE .. any advice is much appreciated .
