Why not just add a ground from the engine to the firewall. If you have no power anywhere check and see if the wires on the solenoid are on the correct side. The power to the car wire on the battery side, not the starter side.

Then if that is OK, start tracing the power from the fuse panel and see if you have it there. If you do, then trace it to where you lose it.

Sounds like you have "zero" coming out of the fuse panel. I'd check power in, from solenoid.

Good luck.
