Another Sr20 no crank, no start. Out of ideas!

I have battery relocated behind the passenger seat.
I also forgot to mention that I have a 12 gauge wire running straight from the starter to the cabin. I just simply grab the wire and make contact with the battery + post so it can crank over and start.
(KInda a kill switch)

Is the battery fully charged according to the voltage you read from your voltmeter and the CCA read from the battery's sticker? Or have you taken your battery to a parts store and had them test for actual CCA? If your ACTUAL CCA has tested to be 750A, then yes, you're good. But I've seen plenty of batteries that have sufficient voltage but no CCA.

Make sure you have good grounding from engine to chassis. I've also seen my fair share of cars not start due to this.

Furthermore, I know E85 will be harder to start than typical gasoline, but make sure your start enrichment wire is powered when the engine is turning over, as it pull timing and simultaneously fires all injectors to make starting easier.
