Can the fuel pump relay prevent the fuel pump from running constantly like it should?

Yes. If the relay has aged the holding coil could become week or intermittent. However, it is more likely that you have a loose connection in the relay control circuit or the contacts on the relay are worn. Also check the wires going to the inertial fuel cutoff switch. This could also be a source of strange behavior. The fuel pump or it power circuit could also be the problem. Good luck!
