There are two wires going to each injector. The white and red wires should have 12V all the time when the ignition is on. Can you confirm this? The ECM creates the pulse by providing a ground (blue and green wires) to the injector.
lf you unplug the injector and put a nine volt battery across both terminals, you should hear it click. If you try this, only do it for a fraction of a second.
