Excuse me jumping straight in here without doing much diagnostics myself but someone here may know a common point and save me a lot of time.
1994 BMW 325i. Starter not turning and no power to the fuel pump fuse. Fuel pump ran when the RAC man put power on the fuse. Starter turned with the screwdriver across it.
Been having the off side sidelights/dash lights fuse blowing regularly so if there is no obvious common point I may have a small furry visitor from t' allotments eating my wiring.
