I know that our 3rd gen cars are "batch fire",, that means each bank fires the injectors once per rotation of the crank.

But exactly how does this work?

Does the drivers side fire on one rotation,,then the pass side fires the next crank rotation,,,

OR
Do all injectors fire at the same time, once per rotation of the crank.

OR
Does the drivers side fire during the first half crank rotation,, then the pass side fires during the second half rotation.

See, I need some help!!!

 

All injectors fire at the same time. There is only one driver in the ECM for them, it is just split into 2 wires coming out.
