I just finished replacing my pump! There is a valve on the fuel rail that you can place a gauge on. The pressure should be in the 35 psi plus range when the pump is on. The pressure should stay hi for awhile after you turn the pump off.
My car was getting harder to start for awhile. An easy method to check for the lack of fuel is to put a little ether in the carb. Does it start then die? If so, fuel problems.
It is a fuel filter (almost never), and injector, the relay or the pump. Injectors normally go bad slowly so you would have had missing and other issues. The relay can be swapped with the starter relay. No crank? Replay replacement time.
The last thing is the pump. If it is not the relay, it is probably the pump. Do not skimp and get the lowest cost pump. Normally low cost is fine, but cheap pumps seem to fail withing a year or two for me.

If the fuel pump becomes noisy you can rest assured it is going bad. But, the pump maybe going bad and not make any noise at all. Anytime you have a problem with fuel delivery, first thing to do is replace the fuel filter. After replacing the fuel filter a fuel pressure test will verify the condition of the pump.
