Thanks for the responses

Finding this Forum has given me a lot more confidence that I can get this car back to its previous glory !

Decided not to disturb the injectors

Crossed everything and gave it a try...........nothing at first then fired for a few seconds....no sign of firing again, so tried Aerostart(Ether spray)........fired up for a few seconds only each time - max ~ 10 seconds.

Some strange noises from the fuel pump

Thoughts..........fuel pump may need further cleaning and output check.........may try squirting some fuel into the air intake next time I get it to fire

Would disconnecting the injector lines one at a time at the fuel distributor (with the system pressurised) be helpful to show me the fuel is at least getting this far -are they just compression fittings or do I need to find replacement seals before undoing anything -my manual doesn't seem to show any seals.
