hey,   my rev counter isnt working, any ideas on first places to check?   thanks

the only reason I can't buy a mk4 is because I want 3 point seat belts in the back, and mk4 have lap belts. I've been told that there is no way of converting a mk4 to a 3 point belt, but what if the rear seat was taken from a later model and fitted to a mk4. Would this fit, to enable the 3 point belt to be used?

Hope some one can help I have a escort mk5 1.8 130 xr3i cab It starts like the batt is flat ! Have a new starter motor, new batt, changed the earth leads and the starter leads and still the same ?? Starts slow the turns over and starts any ideas ??
