Check the fuse box to start with.

It's not uncommon for it to be a simple blown fuse. This will usually take out a few other circuits as well (boot light for example).

Fuse 10 & 21 are the usual suspects.

check the 3pin connector down by the ECU, there is a sleeved black wire there its the feed for the tacho.

Only on early cars.

On facelift models, it comes through the C101 on the bulkhead.

Last case of no tacho I dealt with was a poor connection in the C101 connector following an engine change. It's a black wire, pin 9.
