Shaking the connection can cause it to improve the ground if it is
loose/corroded. Any vibration can do it.
While I was thinking of the body connection since that is what I have seen
go bad (the one behind the number plate in the boot) I suppose it could also
happen at the pump end. I'm not talking about an open, just resistance in
the circuit so the ground wires go hot with a low voltage.
An interesting question is whether a bad ground could damage the points? I
know it can cause problems with aftermarket pumps.

Well, how would rapping the pump body with a hammer (or driving across a
rumble strip, etc.) clear up a bad ground? I can see how it "unsticks" the
points...
A pump that failed to respond to rapping might very well have a ground
problem, sure... (or it might just have good musical taste <g>).
