I too find that the failure of the washer pump exasperating. Nothing worse (reletivily speaking) than having your wipers rubbing dry glass for the duration of the cycle. The culprit pump is of English descent and is, indeed intermittent. Please, no electronic crumpets hurled from across the Atlantic (or Canada, right Chief), I'm only making an observation. While you are browsing your favorite dismantling yard, pick up a few; they're used in a number of GM cars of the period, just make sure the electrical connector is the same, there are a few ones that are different. They're sleepers, though, you go and test them and they work, but a month from now, you go to use it and it won't. No, i don't think they're Lucas brand.
