OK, suck on the inlet hose and see if you can pull anything up, and blow in
the outlet to see if its clear.

If the solenoid is giving a single 'clonk' then either its contacts have got
too burnt to function, or there is a brush, comm or winding problem with the
motor itself.  With this latter possibility if you can turn the motor a bit
and then it cranks OK, it's probably that.  If no difference then probably
solenoid.  Some starters have an exposed copper link between solenoid and
motor, so by putting a meter or test-lamp on that and trying again it will
prove it back to the solenoid (no voltage) or in the motor (voltage).
Solenoids can usually be dismantled and cleaned up, maybe the bridge bar
turned over to use a new surface of that half of the contacts anyway.  It also
relies on the flywheel side of the mechanism being allowed to move forwards
far enough i.e. moving the pinion into the flywheel before the bridge on the
back will extend power to the motor to spin it, so possibly something is
blocking that.

  Paul, yep, there is 3/4 of a tank. And I haven't done anything to the pump,
it has been installed since I have had the car (1988). So it's
  certainly not installed incorrectly. As far as a blockage, I guess that's a
possibility that I will examine before getting a new pump.

  Starter-wise, it turned over fine yesterday (with plugs removed) and when I
stopped cranking it (after cranking it for about 10 seconds), it
  only 'clicks'.
