Well, I have found it, and got the end cap, haven't managed to get a

Looks like I will be able to get it off as its got taps either side of
it! Also been trying to get my head round the timer wiring as I
replaced that last year too with electronic one, as it doesn't appear
to be independantly fused ...

Sounds like you're making *some* progress. Is it possible that - due to your
wiring changes - the pump isn't being told to run? Can you get at its
connections to make sure that they're live when they should be, or can you
temporarily wire it into a 13A plug to see whether it runs when you *know*
it has power? [Even if you can't get a screwdriver in, you may be able to
get a finger in to check whether the spindle is going round.]
It doesn't make a sound when wired directly... its a dodo

Just sourced a wylo (£30 something) locally as its cheaper than the
original grundfos (£57 yikes) ...

Do I have to bleed air out once the new one is in? Getting to the back
of the boiler is nearly impossible ? or maybe I can just bleed it out of
the radiators
