I checked the electrical diagram, but just can't figure it out. It does not appear to be a dedicated circuit in the panel, so I guess you're going to have to start pulling and testing fuses.

I’ve tested all the fuses that I can find and they’re good. I’ve traced the wires to the end. One is a ground and the other goes to the two red buttons on the dash. Regen buttons. I’ve hot wired the fuel pump and it’s pumping fuel but something else must be keeping the fuel from getting to the injectors

The ecu came unplugged. It must have not been locked in. Tractor cranked right up. Now when I put it in gear it won’t go. Just had a new clutch installed last week.
