LH2.2 760 No Spark

Got the engine swap all buttoned up and now I have no spark. I've got power to the coil, power and ground at the power stage, and I swapped in the power stage from my running 240 with no change. No spark out of the coil.

The hall sender is plugged in, and it ran before I did the swap.

I'm fairly certain the distributor was under water during a recent flood, but even if the hall sensor was bad I should still have spark from the coil, no?

Thanks in advance for any assistance.
 
Do you have injector pulse?

Do you have a test lamp?

I don't have injector pulse. I do have a test light.

There's a random hot black wire that's running up the harness with the injector grounds by the fuel rail. Where's that little guy's home?

And I cannot for the life of me find the radio suppression relay anywhere, would this car have that?
 
From what I understand, if the tach needle bounces when you crank, you should be getting signal from the hall sensor.

Here is a drawing stolen from https://forums.turbobricks.com/showthread.php?t=329862. From the diagram the coil pulse is sent from the EZK to the power stage pins 16 (power) and 20 (GND).

It is a turbo, the tach is taching, I have the injector resistors plugged in, I've verified power and ground at the power stage with the key on.

The car ran before I did the engine swap, so I've probably missed something, but all my checks so far are showing that everything should be good. I might have another set of injectors laying around to try. Even if the impedance is wrong they should still fire, right?
