Assuming the engine is running and the only thing not working is the tach; first check 3 things. 1) The MSD tach connection to the tach is good. 2) The tach is getting power (+12v). 3) The tach is grounded.

You didn't say what brand of tach you're using. Some tach's need a tach adapter to work, and MSD has them. Check the installation manuals from MSD and tach. If all else fails, contact MSD tech support by phone or e-mail.
