I just finished replacing the Head on my '96 900S. It restarted but the oil pressure light is on and doesn't go out, did I knock off the sensor wire somewhere? Also I now have a leak where the fuel injector rail connects to the #4 injector. How do these go together/come apart? I assume t is a press fit but do not want to "force" it if this is not the case I have removed the little clips between the injector and rail. As always thank you for the suggestions this is my first Saab that I have been this deep into and your help is greatly appreciated.
