What do I do when both wires have 12 volts (power on, engine off)?

Uh, oh. If that connector is unplugged from the injector, and has 12 volts on both sides, there may be an issue. The computer/module (don't know Toyotas) grounds that ground wire for the length of time in milliseconds that it wants. It's possible there is a 12v feed on the ground side to prevent any fuel from being sprayed when not wanted, however...
I'm wondering now if your voltmeter can't catch the injector ground pulses fast enough to tell the difference. It still could be that you're on the wrong side of the injector...
