cheap way: disconnect the fuel line at the carburetor or fuel rail and crank the engine, if it starts shooting out it works (at least partially)

otherwise take it to a shop and have the fuel pressure checked, that's cheaper than buing a pressure gauge yourself

or... get a wire that's long enough to run from the positive side of your battery to the ecm diagnostic port under the dash just to the right of the steering column. after you hook one end to the battery, touch the other end to the first prong in the second row of the ecm port. this will bypass everything and energize the fuel pump directly. you will hear it come on in the fuel tank, though sometimes its very faint. but just because you hear it doesnt mean the fuel pressure is steady, that will still have to be checked with a gauge at the fuel rail valve.
