Slow down; you're getting wrapped around the axle with misleading tests. Your test light grounded the coil of the ASD relay causing it to turn on. That's the job of the Engine Computer. Rather than tearing the Power Distribution Center which can be a pain to put back together, just measure that voltage at the coil or any injector, dark green / orange wire. That's the voltage that comes from the ASD relay when it turns on.
That relay turns on two different times. The first time is that one second when the ignition switch is turned on. It's very easy to miss it with a digital voltmeter because they often don't respond fast enough. A test light does a better job. Since you found voltage feeding the ASD relay contact and the coil, we know that part is okay. If you still don't find that voltage turning on for the first second, we have to determine if the relay is not being turned on by the computer or if the voltage isn't getting to the coil and injectors.
Use the test light to double-check that voltage at the coil. If it's not there for the first second, hold your finger on the ASD relay to feel if it clicks when a helper turns on the ignition switch. If it doesn't click, I suppose we could have a bad computer but that would really be rare. If it clicks but there is no voltage to the coil or injectors, look for a break in that dark green / orange wire.
