I'm not sure why they don't just use N-Type transistors here. I'll try to figure that out, but it is not really relevant because they just don't. Everything should still work, just be aware your 2A fuse could blow and toast your coil, injectors, and possibly your battery if you don't notice it has a new 20A draw on it.

The injector drivers do use N-channel MOSFET's. The main problem is that power could backfeed through the flyback damping circuit, keeping the ECU powered up as long as the injectors are powered.

The MOSFET's might occasionally stick open because there aren't pull-down resistors to dissipate the gate charge, but that isn't a common occurrence. You could install pull-down resistors (10k or 100k ohm from R15 and R20 to ground), but as you noted, it's much better practice to just ensure the ECU controls power to the injectors and coil.
