If the power wire to the injectors grounded out the motor would die too fast for the ecm to log an error I would think. From my understandig the emc looks for parameters out of range for a specific time then it sets a code. Once the ecm detected the engine had stopped the error logging would stop.

Also a note on the Pink/black power wire that is the common hot wire for the injectors:
I'm guessing it's simular the 86/87 where the same fuse powers the fuel pump and injectors... If this wire shorts out and it dosent blow the fuse then there is a high resistance (poor connection) in the line some where. Most likely at a connector.

An example of this is a bad connection at the battery. When you would try to start the car the load through the bad conncetion would cause a voltage drop across the bad conncetion and the soleniod would click on/off. Each time the starter contacts made the voltage would de-energize the solenoid and the solenoid would drop out, then pull back in as the starter contacts open back up and the voltage rises back to the supply voltage.
