Make sure the thermocouple is in the flame from the pilot. The first 1/4" there is nothing there. Make sure that the other end is screwed in tight to the valve. If all else fails go to ACE or somewhere and buy a new one for about 10 bucks, they are all the same except for the length....
You could also have a bad valve but more then likely I would say what I wrote. You will see two dissimilar metals at the end, that what creates the magnet that opens the main valve.
