Follow theduke03's good advice. What you should be seeing, and hearing, is the gas valve opening for the pilot to light, then the pilot lights, stays for a few seconds, then you'll hear the gas valve close and the pilot goes out. The process then repeats itself. If this is not what you observe, please tell us what happens. Watch the furnace ignition sequence as someone else calls for heat at the thermostat.
