Thanks! That's one thing I noticed - that the car fired on starting fluid that made me think it wasn't the ignition amplifier, but I couldn't find an exact cause.

I've used backprobing the injector before to monitor firing/non-firing. It works just like a NOID light. I can't remember if I had it bridging the injector or if I had it from injector + to ground. LEDs take much less power than typical test-lights, if that matters.
The light is off when bridging the connectors, then when the ECU grounds the other side, it blinks briefly. Using the self-test mode, it blinked when the injectors fired. I had a video of it on youtube at some point when I was trouble-shooting what turned out to be a shorting wire to the throttle switch (it shuts off injectors when closing the throttle at cruise!).

Cheers!

And yes, it's Bosch. The in-tank pump is running, but I will replace it when I get around to fixing the sending-unit.
