I forgot to put that once it has finally started it will then start no probs!
What i know that has been done is both fuel pumps have been replaced and the fuel pump relay, this is all that the diagnostics have shown, BMW suggest that it could be an immobiliser fault / keys or ignition switch, I did see on the net about faulty oil pressure switch poss. I am really with this i like simple cars. Any help will be very appreciated
