So mine isn’t an M but I did a motor swap from a sulev to a non 3.0 engine Ms45.1 and I finished the swap got everything hooked up and did an ews delete and flashed the ecu. I’m thinking it’s gonna start. It didn’t but instead I got hit with these three codes.

The starter makes a really loud click but doesn’t crank what do I possibly do to fix this.
