We have exactly the same problem As ZAF in the interior of British
olumbia - blooms, then fruit, then they turn yellow and do not develop.
However a couple of cukes have developed on a couple of the plants - does
this eliminate the pollination problem as a cause?

No, I think that inadequate pollination would still be a prime suspect.

Either most of the blossoms are not being properly pollinated or the
cucumber vines are aborting the fruit because they are under stress
(examples: disease, lack of some particular nutrient, too much shade).

It's easy to find out, cut one (yellow cuke) in half and see if there
are any seeds. No seeds, it didn't get pollinated and it's being
aborted.
