Thank you Bob and David, very helpful, and I know from the history file that Interpro in Bristol who fitted the Omex. However, having just spoken to the very knowledgeable boss, he assures me I will still have a fuel pump relay somewhere as all they would have done is pick up the earth from it ?? When hopefully the Covid situation is better, I'll take the car back to them to check the mapping, and maybe they will remember where the relay is. In the mean time, the search continues.
