There are Elsawin procedures for testing all the components. *removed* That was dumb of me, clearly G40 and G163 are different and not swappable. Coil packs you can test by swapping, if one cylinder is misfiring, swap coil packs with a 'good' cylinder and if misfire moves then its likely that coil pack.
I too find it hard to believe its any of these components which all worked when you left the car, still betting its a bad earth or corrosion somewhere supplying low voltage to components. Another random thought, is your ECU box dry inside?
Attached is the Elsawin Hall sender testing procedure. Here is an interesting extract:
Even without a signal from the Hall sensor, the engine will continue to run and can also be re started.
◆ When a fault is detected, the engine control unit produces one spark for each cylinder on every crankshaft revolution.
◆ The fact that the control unit is out of phase by one engine revolution does not have any noticeable effect on the injection system. If this happens, the fuel is injected "upstream" (before the closed inlet valve) instead of while the inlet valve is open. This has only a minor influence on the quality of the air/fuel mixture.
