Hi Alister ( and anyone else interested)
Late yesterday (* Friday) I finally found the cause of the problems.
The issue had been sudden loss of side lights/headlights ( ALL rear lights worked)
However when I turned the headlights on the fuel pump/ignition powered up.
The engine started and ran fine.
The fault remained elusive all week with all relays checking out etc.
I then decided to test all earth connections at plug end. Having already found some of the many earth connections to the chassis to be slightly loose ( vibration?)
I found some voltage within one section of the earths in the loom and finally traced back to a small plug that had "The Fuzz" growing on two connections a live and an earth. This connected the two and caused voltage feedback to the pump or vice versa. I even think I found the reason for "The Fuzz" which was caused by moisture. More and pictures later as I put everything back together.
