So I replaced my melted ECU with a new and now my Galant doesn’t run at all. Won’t even start. Although oddly enough it cranks over better. That could just be, because it had been running so engine bay temps we much higher than the negative temps outside.

What exactly do you mean by “new” ECU? The capacitors in those vintage Mitsubishis are getting pretty long in the tooth. All it takes is for one to rupture and no more go for your car. The sad thing is sometimes it’s not even visible and the ECU could have tested good mere minutes before you plugged it in and turned the key. I have repaired a few 3000GT and DSM ECU’s because of bad caps. I’m an electronics tech, but I can only repair them if certain parts are bad like caps. I don’t repair them professionally, so take this with a grain of salt. It’s could be just getting to be that time you know? It might be worth looking into if you’ve exhausted other options.

I opened up the “new” to me ECU and yup bad cap.

Question: would it be possible to fix my original ECU. Here’s some close ups of the damage I found on it.

Yup, there’s even scorch marks on the casing. No idea what happened.

If you can find a part number on the IC’s or in a schematic you maybe could. Those IC’s might have been custom and not available anywhere else. Old electronics are like old cars you can fix anything if you just had the parts. The new to you ECU is repairable because a cap is a cap, and the ones on it should have a rating printed on it. It may not look the same, but it will work the same. There are still lost of good parts on your old ECU and you will see more and more frankenstein ECU’s in the future just to keep the car running. There is always the aftermarket ECU’s as well. I would go ahead and get them all replaced if you have someone work on it. Try to find caps made in europe or Japan, those companies use better materials than some Chinese brands. I stay away from all made in China caps because of that. You might be able to find a college kid that’s studying electronics to fix it. Your soldering level does not have to that high to replace the caps. Watch a few Youtube videos, buy a soldering iron, some soldering supplies, and a few of those thru hole practice kits on Amazon. Put together and take apart those kits a few times and you will be a pro, and hey now you can mod your Playstation 1 if you still have one lol.
