Looking at the DME schematic, this means the power was coming from point ADV7 or from pin 4 of the DME CU which appears to be wired back to the start position of the ignition switch. Do I understand that correctly? Just trying to identify things I should test if we see this again.

If you are seeing battery voltage on the injectors with the key off it is probably not coming from the DME.
Earlier in this thread didn't someone add some wiring as a supplemental path?
New DME Relay did not make my Fuel Pump Work
How is the scope working?
