I had my computer open last time this issue came up. There was no discernible damage to anything, all connections looked fine. I’m not so sure about the “5 minute” fix stated above. You will need knowledge about everything on the motherboard, a micro solder kit, and some reading glasses to start…

Haha for me it is usually 5 minutes and because I already see the failures! Quick and easy, the failures are at the connector housing and fail due to vibration/removal. Reflow these points and/or add solder and be on your way. Perhaps its my young eyes as well...but reflowing isn't hard on these, commonly accessed fine tip is all you'd need and some good silver solder...which most diy auto folks should already have.
Reflow all circled items as this is how the circuits are fed and are your issue. If the remaining two I did not circle are cracked, reflow as well, I just can't see from picture. The rest are all terribly cracked.
Resolder all the connector pins and anything else suspicious looking under a good magnifier. I desolder and then apply a bit of flux then resolder to ensure a good connection. Typically it will just be the connector but anything with a thick lead or that is heavy can cause problems. Also remove those dabs of glue on the top side, they were there to hold the caps during the original soldering process. It can become conductive over time.
And clean that nasty flux off there that Denso left.

The open port in your last pic could be your problem.
that bottom pic looks to me like a temp sensor, aftermarket or foreign (?) US are different. This would not cause your issue (if that is a small brass fitting into the block with wires attached). Not sure if you have investigated your emissions computer or fuel solenoid yet but that’s where I’d start. Both simple to check. Chasing cut wires and random components will make you a little batty. If the above 2 check out, my next would be removing top of carb and inspecting the jets. Also, remove fuel line at carb and make sure pump is pushing fuel to carb. There is also a little mesh filter on my solenoid, remove, inspect, clean.
