Quick update after all that work and contorting my fingers to get the new relay in, the initial response was not very positive but after charging the battery overnight car started without hesitation until I drove it out of the cul-de-sac, and just to completely destroy my confidence it died.
What me and Auto Electrician saw today was the car started up fine and I could not replicate the failure even went for several runs but then he decided to make sure anyway and when he moved the fuse box out of the way the car immediately died
Auto Electrician suspect the relay socket clamps that grab the pins of the relay is slightly worn so pinched them -reinstalled the relay and it started up right away for good measure we have left the covers off as we both doubt that this could be the end of it.
