Yea the red and white wire you mean? It has 12v all the time. It’s hard wired to the battery side of the shutdown switch.

I can’t tell if it’s dieing because bc fuel tables are crap, as in too lean. Or if their is not enough air and it’s too rich, and I need more throttlebody gap.

Do you have the red fuel pump feed wire to 12 volts? Even if you are not controlling the fuel pump with the ECU it will need 12v to that wire. If you need more help I am willing to talk on the phone and see if we can get it running. If we go that route, email me your tune and I will look it over.
