well, its all sorted

thanks for al your help,

bought a haynes book of lies, identified what wire is the pump power wire, put a meter on it, and only read 7v, odd i thought, so i chassed the diagram back and it goes from the pump to the inertia cut of switch (which i know was good) from there it goes to the fuel pump relay, i had swapped this with the main beam relay which i know worked, then i saw that there is a main ON relay, basically a bigger relay that powers all the small relays, swapped this wth the same one for the rear screen heater, and bingo, turned the key, pump primed up, car fired right up and pured like a kitten, very happy bunny

so just the rest to sort now
