tach not working

Randomly, this morning, my tachometer decided it wasn't going to work. I recently changed my gauge faces on my dash but everything has been working fine. I've already checked the fuse... any suggestions or ideas? Any guidance would be great!

Tach no workey

The tach gets its power from the same fuse and has the same ground as all the other gauges.
So if it is the only gauge not working there are only two other things in the system. The Tach and the PCM.
So lets hope that it is the tach. Its the only thing that makes sense.
