The service manual calls that a power transistor. I can see why someone might call it an ignition module if they're used to other systems, but it's way simpler than that name implies. The ECU controls the ignition timing. The transistor just amplifies the ECU's signal so that the ECU doesn't have to power the coil directly. It's basically a relay, except it doesn't have moving parts to wear out. Unplug the coil and test its connector with a meter while cranking to see if power's getting to the coil. I'd crank it for a few seconds just in case it takes the computer a second to work out what position the engine is in before firing the plugs. (IIRC it waits for the sensor in the distributor to see cylinder 1 hit TDC before it starts firing the injectors--I don't know if it does the same for spark.) If you have no power across the pins in the coil, I'd check from the blue wire to ground (like the intake manifold) to rule out an issue on the ground side. If there's no power, and the transistor's good, the ECU may not be getting signal. If you crank the engine for a few seconds and then run the codes, it should throw a position sensor code if that's the case.
