Thanks to all who responded. I should have added a little more. I did bench
test all the pumps by using a 12v battery and connecting directly and none
worked. Is this the correct way to bench test one? Since this is the first time
in probably 15 years I have messed with an SU pump, what is the proper cleaning
method for the points (as I remember you used a crocus cloth)?

Yep. Probably something very simple.
I've run into a few of these myself when the pump has sat for too long.
The points in these pumps are prone to oxidation if they sit for too
long. I came up with a theory that the anti corrosion wrapping paper
used in the original packaging may be out-gassing and making the problem
worse.
The turnover in the UK is fast enough that the manufacturer doesn't see
the problem, but by the time they make it to the US and sit on a shelf
for a while the points may be getting contaminated enough to cause
problems.
Burlen Fuel Systems seems to be aware enough of the problem that they
now include a note stating that removing the cap and cleaning the points
will not void the warranty.
Check the pump on the bench, if it does not work, remove the end cap and
clean the points by passing a piece of fine emery cloth between them.
Recheck the pump and it should work fine.
Kelvin.

Good chance it is just the ground wire. I do not know what year the
break off is but my 67 has the ground wire going to one of the license
plate bolts in the boot. I think the later ones are viewed from the
passenger side battery box near the pump itself.
Very common problem.

I have what should be a simple problem that is driving me nuts. A
friend was doing some work on my 69' C and found the fuel pump did not
work (car had sat for 5 yrs). I then put a new pump in that I had for
about a year. Didn't work. I checked the voltage and had 14 volts to the
pump. I put in another pump that I bought a few yrs back at an auction
and it didn't work. Am I overlooking something simple or can you have
that many SU pumps not working?
