I can see the ECU plug has gone funny, so try to clean it with contact cleaner but NO LIQUIDS on the ECU itself. It would be miraculous if you found a brand daewoo ECU again. Daewoo for 650 & 250 have historically been sensetive ECU’s and most difficult to acquire.
While its apart, you would also want to go over the harness like a fine tooth comb.
