You you aren't actually sure whether the ECU is turning the injectors on I assume. All four injectors get power all the time, and the ECU completes the circuit to ground to turn on the injector. So if you're just looking for 12V at the injectors, all you know is that they are getting power; you don't know if they are getting turned on by the ECU or not.

It's possible you have a problem with the OBD0-OBD1 harness or have the wrong harness. I think there are a few OBD0 connector pinouts if I remember correctly, but I'm assuming you know enough about your car to get the correct one so I don't think that would be a problem.

But just looking at the big picture right now, coule there possibly be a timing issue since you had to pull the head and such, i would go ahead and double check to make sure everything is good.
