Thank you. I made a rookie mistake here. Forgot I had relieved the system of all pressure when I pulled the motor. Duh..
The motor had been out for over a year to get the full build done. Lots of little things to forget.
Bringing back a dead post, I know.
My NB1PNP shows a fault for alternator control too. But it is indeed actually working.
The only way I can really tell though is that my battery hasn't died though.
Indicators and headlights are direct-wire to the IC7 not over CAN. Maybe reach out to Haltech to see what they have to say. But I don't think the IC7 can receive those signals over CAN.
This is the exact injectors I have.
Thank you to everyone involved. I was able to source the data, believe it or not, from these forums as follows:
