HOW CAN I FIX MY APRILIA HABANA?

Hi there, I have an Aprilia habana custom 50cc. The bike was fine until i came to start it yesterday and it wouldnt start, i tried the kick start and checked the plug, the plug was fine so i stripped the body work off and checked all the pimbes. There is no blockage whatsoever. so i took the pimb off the carb and kicked it again and no fuel is coming through at all. I was wondering if you could tell me what you think this might be? i personally think it could be the fuel pump as all the pimbes are clear but theres nothing coming through but i'm no machanic.hope you can help
