Sounds like a ground issue possibly

I agree with a grounding issue, which could also explain the fried ECU.

Probably best to start at the negative battery terminal (the large cable and the smaller wires on the screw post) and follow the wires from there checking all connections and for ground with your multimeter. It would be a good idea to check the ohms (resistance)on all the primary ground wires to make sure there isn’t an unseen issue with the wire itself (like major corrosion inside the casing or a break).

Good luck and just remember the number one rule of wiring I was taught many years ago: Don’t let the smoke out of the wire, if you do you are fuc*** hahaha

I think there’s also a ground cable from the shelf the ECU sits on to the engine block.

not sure if it was the + or the -, but cleaning the corrosion off of the connectors and terminals as well as the quick-connect fixed the issue. Was probably the only issue last year before I fried the ECM for $900. Lake testing today
