[fixkick]

gosh so sorry to hear that, what a travesty. !
nice photo and in car, too. very good.

that 58b30 is clear
but the xxx-MT what is xxx (county for sure but what?)_
53s. is FED ECU. that xxx is, i bet FED-MT (many are marked, US-MT this means its for both calif and FED, 1992 was the first year for Calif suzuki's


here are the USA pages

the Fed ECU , the best i can tell is only 53s, means its bad.
the FED ecu has no way to connect to a CALIF EGR.
53s are the most poorly documented feature at suzuki
i think it means the memory is corrupted, (or even bad CAPS , its crashing)

all is right here, i see no errors by PO. no wrong parts.
your good
id now put in all new caps. ( 2 of them)
and look for acid damage. below caps.
see red dots
C103 is prime to change.

the acid needs to be neutralized first. with baking soda.
or it will eat the copper traces off the PCB.
bad news. and 53s.
the bad cap allows the regulator to drop out and memory fails, this can cause 53s.
i think the ECU does a self check , check sum (CS) and if it adds wrong, bam 53.s
and dirty power is my first check. C103
