      Not a crank sensor problem as one controls spark and fuel and the other
      controls timing. If it has been sitting for a while, you may need to remove
      the injectors and clean them. I have seen injectors lacquer over after
      sitting for a while. In addition, is the car auto trans or manual ? The non
      cranking could be either a ign switch or a neutral safety switch.

      I recently bought a non-running '87 528e. The ignition switch is non-
      functioning (at least to try starting the car, but seems to be ok in
      the "on" position), so I jumpered directly to the starter soleniod to
      turn the car over. The fuel pump does pressurize the line, and I have
      spark (the car will start on starting fluid), but the injectors are
      not doing anything. My question is this: does the car time the
      injectors the same way that it does the ignition, or does it use a
      different sensor. I think I can see two reference mark sensors (look
      identical to my Porsche 944's) so I am thinking one may be bad if one
      is for spark and the other for injection. Let me know if I am correct
      in my assumption or if I am way off base here.
