My 1990 325i would not start after a trip to the local hardware store today. I had the car towed home. The car starts and then shuts off almost immediately. So.....I think it is the fuel pump because I do not hear any noise from the gas tank when turning the key to the on position. Is there a simple way to check if it is the fuel pump ? Is there something else that I should be checking? Thanks for any replies.

Fuel pump relay. Crankshaft position sensor?

The pump doesn't run continuously when the ignition is switched on - it might flood the engine if an injector was leaking and otherwise would run down the battery unecessarily. Not sure about your model, but some run for a few seconds to pressurise the system - others just when you operate the starter and of course when the engine fires.
Fuel pump and the main PI relays are always the first suspects, though.
