Stove top gas burner does not lite

3 natural gas burners lite and work fine… the fourth burner does not lite; ignitor works but when I turn knob I do not hear gas flowing through the tube.. ???

Remove the top panel and clean the orifice for this burner using a needle or a toothpick. If it would not help then replace the gas burner valve.
