I know this doesn't explain why your CS injector doesn't squirt, but based on Service Bulletin # 135 from January 1990 (applicable to '89 and '90 740 and 740GL), that 3-2-1 may be a false code, due to a circuit modification.

As a quick check, peel back the connector boot and see if the Blue-Green + wire has been disconnected, taped off, and replaced by another wire (color unknown).

If so, you can confirm the modification by checking for continuity from CS pin 2 to
starter auxiliary terminal 15a or 16.

Post back with your findings and I'll fill you in on the details.
