sounds more like a broken tach to me. But then I know nothing about diesel engines. If the engine runs, you have some RPM's going on. after all Revolutions Per Minute have to be present for an engine to run at all.

Hi and welcome to CF from Tj. The plug may have come loose behind the dash or its corroded. I would take it apart (Very Simple) and disconnect the plug and spry it with contact cleaner. About the knock, when was the oil changed last? ...Tj

The tachometer used with the Renault 2.1L turbo diesel powered Cherokee XJ gets its input signal from the "W" or "Aux" blade type terminal on the Paris Rhone alternator used. You might want to check that connection.
