Check the fuel pressure, kinda sounds like the pump is toast

like he ^ said or you've got some dirt blocking the prefilter. Also wouldn't hurt to check/replace the filter too if you didn't do it in a while. As long as the pump is spinning these are pretty much the issues that can prevent the flow of gas (bad pump, pre-filter, filter).

TBi needs 14.5psi at the injector (aka after fuel presure regulator) i think the pump is soposed to push at abut 17psi.. i could be wrong on the pump pressure as i could only find the injector pressure in my manual...
