I have replaced distributor replaced ccrm checked all fuses all wires no vacuum leaks have checked everything I possibly can and sometimes my fan and fuel pump would randomly turn on when the key is on
So I am thinking my ecu is the suspect so I took it apart and everything looks fine except this one spot does this look burnt to you or do y’all have any idea

have you pulled any codes? You can do it with a paperclip and a youtube video.

Yes I have tired it and it doesn’t flash to pull codes tried the paper clip method

did you check the fuses under the hood as well as the dash? How did you check for vac leaks?

Looks burnt

Definitely looks burnt, I had problems with ecu, but my caps went bad. Almost looked like tiny metal specks on the board, hard to notice. The replacement board I bought had the same issue but jumper wires were soldered in a couple places.

there is one spot that it looks like the trace might have lifted. A little solder would fix it if that is the case

Maybe, but most likely not. If me, I would replace it, you know at least 1 area is burnt and you are having issues that others have had with bad ecu’s. Just because you don’t visually see anything wrong with it, doesn’t mean it doesn’t have problems. Good luck either way.
