If you're just using a simple multimeter to measure the voltage, that
sounds correct. The injectors are pulsed, so even if they get full
voltage when pulsed on, the meter will average the voltage down. You
would need an oscilloscope to see the actual drive voltage.


Pull the injectors on one side, and check the spray pattern.
