Very interesting, not at all like the last diesel I worked with :o)
The third generation electronic injectors with piezo actuators is an
interesting twist. I knew piezo actuators had been developed, but I didn't
know they had been implemented commercially yet.

Back to the subject at hand, judging by the diagram at the bmwworld link
above, interrupting the power to the pump would not be a good choice.

Interrupting the power to the injectors might be an option.
