The pump relay is on the "firewall" under the dash.  Could be bad, but
chances are your trigger points are dirty, in the distributor under
the breaker plate.  Two screws on the outside gets it loose.  Use
clean brown paper to clean between the points. Don't file!  If you
pull the distributor, it's much easier to work on, plus you can check
the make and break on the trigger points without cranking the engine
over.  Sometimes minor(really minor), bending is necessary to
compensate for rubbing block wear on the points.  Also check
continuity from the socket to the points, I've had one set that had an
open where there was a rivet.  Sounds like maybe the control module is
timing out, you have a 2-3 second run of the pump after the trigger
points quit opening and closing.  On another odder note, I had the
same symptoms with a loose plug on the ignition switch at the base of
the steering column.  I think that '71 is the only year for that plug,
though.  If you don't have the Bentley factory manual, better get it
before proceeding very far with FI troubleshooting.  Muir's Idioit's
Guide also has a good section on FI troubleshooting but the circuit
diagram is pretty generic.  Your really need both books.  So now you
have a spare fuel pump.  Hang on to it, you may need it someday.
