The sensors are digital. "continuity" eg Ω likely to give very odd results and different depending on which polarity you measure.

Most of the sensors I've worked on measure mA not volts making it quit difficult to determine faults with Ω meter unfortunately.

I don't remember how the injectors are fired but it's more common turn not that 12v is a constant and the trigger is when DME pulls the signal down to ground. There is I believe a ground wire to actually run the power.

If no signal to the injectors and everything else was working before you worked on it, EWS is most often the culprit.
