My '02 Bird won't start !

[BLUBRD]

It has sat for about a month, but that has never been a problem before. It only has 3700 miles on it and the battery is fully charged and hooked up to a trickle charger. The engine cranks just fine but, it seems like it's not getting any fuel. I went to take off the air filter so I could pour a little gas in the carburater, but...Hmmm is my age showing? I'm not sure if my gas got gummed up or if I have a little vapor lock. Any Ideas would be greatly appreciated.I live in Dallas and were gonna hit 80 today so I don't see the temp as a problem.
