If necessary I will replace faulty wires, but his should do the trick.
I would check for ground again with the connector removed from the ECU or with the wire depinned.

Yeah. Did exactly that. The harness wasn't connected to the ECU. I fixed the grounding issue and the car actually started

Sounds like some real progress. Keep us posted!


Edit: Post 420 -sweet.

Edit: I wouldn't be surprised if you have two working ECUs. I'm sure this has dawned on you already but I thought it was worth mentioning.
