Would the wrong sensor cause your gauge not to work?

Yes. IIRC, there are 3 different resistance ranges in the square body run of years. Plus many of the aftermarket sensors don't match the GM values. You can't just go by the terminal types as I think some of the resistance range changes didn't match the terminal type changes.

And you can add in the ever popular installation of an idiot light sender in place of a gauge sender.
