Don't know if the 78 930 14-pin engine wiring harness is the same as your 87.
To test harness, separate the plug, check continuity from pin 10 to both the WUR and AAR plugs. No continuity, broken wire. If ok, wire in harness is ok.
Turn ignition on, test for 12V on socket 1/2 of 14-pin plug. If no voltage, fuse, broken wire or possibly another fail safe power disconnect?
Don E. knows his stuff but just to assure yourself the fuel pump shut off microswitch on the top of the CIS isn't serving to disconnect +12V to pumps and the WUR/AAR, pull that green plug on the back/top of the CIS, re-check for 12V
If you are getting a 10V measurement it may be a wee bit low batt. Long runs of 16awg wire can really attenuate voltage signals. Test battery voltage at the battery posts to see where you are.
