The tach is electrical. Check the "METER" fuse in the fuse panel.
The speedometer is totally mechanical. If it's jumping, make sure the cable is securely attached to the back of the gauge. It can fall off sometimes. If it continues to jump, replace the cable.

we tried replacing the trailling coils with a good working one and the tach worked for about 4 secs, as it revs up to 3k then the tach cuts out completly, does this every time we start the car, does anyone know what could be the problem?
