What wire colors do you have? And how many wires in all?
Edit: Saw your previous post and these are not the factory wire colors just to let you know. W/the plug connected and key to on one wire would have 12 volts, another 5 volts, another 2 volts, and a fourth is the ground and it would have zero volts.

Well of the two wires you had no voltage from, one is a ground so that explains that, but the other wire should have two volts, but as mentioned, the plug needs to be connected to the sensor when taking these measurements.
Secondly, how did you come to the conclusion that the injectors were not opening? The injectors which are easily accessible are the secondary injectors and these don't activate unless the engine is under load and the rpm is above 3800. The primaries are installed into the engine and are hard to access so how did you check these if you checked them at all?

At the ECU pins 3E (Light Green wire) and 3C (Light Green/Black wire) are the primary injectors. W/key to start these pins/wires should pulse a ground. A meter would be hard to use but a set of LED lights will flicker indicating the ECU injector drivers are working. One of the LED wires goes to the injector pin and the other wire goes to a voltage source that has power w/key to start and that would be pin 3I (Black/White wire). Do not use any other type of bulb except for an LED as you can burn up the ECU.
And do you have a spare CAS?
