1. I imagine you have other gas that is working. Has anyone recently shutoff the gas? Next troubleshooting point is the control and gas regulator, if you have not picked up a draft. Perhaps you have gone as far as you can; safely.
2. call a pro soon. You can die from unburned gas.
3. This is a long shot, but make sure you turn the control knob to the Off position for a few minutes before you go to pilot . Then press the button and hold for a good minute when you light it again.
