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

[Edit]

Answer

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!
