I would highly doubt a sensor issue as it affects multiple gauges that receive info from different sensors. Also check the connection back to the sensors, a little water or corrosion can wreck havoc, and a shared connector could also be the culprit.

When pulling your motor, the tech disconnected several grounds.
Check all for a good connection.
Also, +1 on the fuse. (#8).
Good luck,
