No spark and i can only get 5V at the coil.
I wasn't automatically saying it was the ecu I just did a quick parts check for what's available in the area.
With the one wire test in your pictures it looks like your jumper from the ecu case to negative battery terminal is disconnected so that's how I set it up to do the test.
Does it matter which one you disconnect? Because with the setup you started with(just like below) I got no spark when grounding it.
But when I switched it to the other post that went to the distributor I got spark each time I grounded it. Mind you both tests were done with the battery negative to ecu case jumper disconnected from the battery.
