'91 420 SEL Tach
Tach stopped working. Everything else on dash still works. Checked all the fuses. All good. Any ideas?

Since the car still starts & runs?
The RPM signal must be there or the fuel pump would never work. Either the wire at the tach is disconnected OR there is an issue with the tach.
