I did a B16A swap into an 89 hatch. I have a PR3 ecu. Everything is wired correctly. I just don't have any power going to my ecu. Starter turns over, fuel pump engages, radio works, lights work, etc. Just acts like ecu doesn't have power to certain pin-outs. I did have a check engine light on for a while, now nothing. Any suggestion would be appreciated and used.
