The injectors actually fire once each engine revolution or for our engines every other spark pulse. All four injectors fire together.

If the FI fire everytime a spark fires, and there are four plugs sparking at different times, does that mean 3 times out of 4 we are throwing fuel into a cylinder that is not firing? Where does that fuel go, is it wasted?
