what you did wrong,
not checking fuses first.
not seeing if the CEL lamp is dead. IT MUST NOT BE DEAD.
or not using the DLC connector to jumper clip it and get code 12 and not 41, nor 42, or both DTC codes.
the ECU may be dead.
it happens when caps are dead or worse, if worse the acid leaks out and eats up copper tracers, at all levels some do and burn up (ask in carbon)
your spare diode might work (polarity correct) min to minus , plus to plus.
your ignitor is ok, most are , testing it is tricky see other post link above.
this is DOOMED. the acid wrecked the FR4 PCB board material, then made it conduct electrons and burned to a crisp, acid loose is never good.
if you look you see the carbon cloud from smoke damage, NEVER A GOOD SIGN that. is hopeless.... (now only for spare parts ECU)
I can not see your ECU, like this.
