If the engine runs on carb cleaner/ether, then he's got spark; that is, he's got a functioning Hall sensor, which creates the tach signal that the ignition control module uses to fire the coil and, in turn, the plugs, which burn the carb cleaner. No Hall signal = no spark (no combustion).
For 16V Turbos, that same Hall signal is passed on to the ECU, via the ignition control module. The engine ECU does not control spark; it only accepts a tach signal, which it uses to time injector pulses.
