Key question, how much WD40 is he spraying in ? Is it enough ?
Whilst I agree that the key problem is fuel and getting it out of the fuel pump and through the injectors from the experience of owning a BMC 1.5 for several years one key point in starting is the speed of cranking and that is down to the battery type. Changing the battery used for starting to a heavy duty car started battery changed the engines starting characteristics dramatically. Once the fuel problem is solved fit a proper starter battery fully charged and she ought to run with much more ease
Stop right now chasing fuel problems!!Update - At the end of yesterday the fuel flow was good, 12-15 drops after 10 seconds cranking, but today I'm back down to 2 or 3 drops from the same, at injector end of hp lines.
In middle of going over lift pump again now while I have daylight, but shall go over and reply to comments that don't ignore the information I provided later.

I think we've narrowed down the problem to the injector pump (lift pump was a black tarry mess, but clean now, everything else also cleaned, and yes, cut out is in run position). The workshop service manual does cover the injector pump, but I don't think I have the specialist tools for full service, but the thread I shared suggests that cleaning the gause is possible without full service. Besides, as you're all no doubt aware, there's a big difference between servicing an engine in a workshop compared to doing it aboard a vessel at anchor/mooring. So any advice regarding this would be welcome, thanks.
