Measure the voltage between them. Does it show 0V or +12V?
Since you say they're stuck open, it should show 12V between the two wires.
If they are closed, it should show 0V.
If they are really stuck open, either there's an injector wiring issue or the ECU injector driver is fried, in which case you have to get a new ecu.
