OK - Not too hard to pull fuel rail off the engine on my M but the electrical connections on all the 6 cylinders are on with a little clip shaped like a box under all the protusions on the injectors.

The wire clip that goes around the female connector that attaches to the fuel injector has to be removed entirely to get it off and then it just slips out = talk about a pain in the ass getting them back on - you need a little pick and some very fine needle nose pliers or needle drivers
