Dear Nicksaph,Hey!, that was inspired. I went out first thing this morning at 7am and found the right Relay labelled 'Benzinepompe' under the glovebox. Changed it and she started at once. A long test run tomorrow is called for, and even if it does turn out to be somethng else in the system at least I now have identified the right Relay so can check continuity, etc, as per Tabetha and Martin's suggestions. A major step forward so VERY many thanks. Cheers, Richard
