Answer
RAVE does not cover the pre-1995 vehicles.  The printed workshop manual has a procedure to test all the fuel injection components with a multimeter and hand tools.  No special computer is needed.  YOu could order the proper manual from Atlantic British or Rovers North here in the USA.  That's what I suggest - follow the steps in the manual and you should get to a solution.
