From your description, I would guess that either the float is stuck in the closed position or the fuel valve is stuck in the closed position. This is quite common with a vehicle that has sat unused for some time and modern fuel. When modern fuel evaporates, it leaves a gummy goo that glues things together. Disassembly, a good cleaning, and reassembly with a new rebuilding kit should correct the issue.
