The engine compartment circuit in the '87s is fed by a 2.5 wire from
alternator B+ to a distribution terminal in the terminal box on the
firewall, Bentley 97.104 track 5.  From there it goes as a 1.5 to the 30
terminals of the ECU and fuel pump relays, 97.106 track 31-2.  ECU relay 87
feeds  all the injector hots plus the fuel pump relay 86 terminal, plus the
idle stabilizer and power-steering switch.

A short to ground anywhere along this path will smoke the harness between
the short and the distribution box.

That would be an ECU failure or a short from the injector ground to chassis
ground (the ECU fires the injectors by grounding them).
