Speedometer???

[E2Dac]

Took my car out the day looked down to see how fast I was goin and Speedometer read 0 all other gauges work where should I start ...the car does have a Electronic speed Calibration box hooked up by my shifter under the boot if that has something to do with

Most likely the calibration box. It either died or a wiring problem has developed. Check all connections and see what you find.

Its most likely the wiring on the speed cal. That happened to me but bc i did a lazy job on wiring. It came undone and wires were crossing. Easy fix.

You could stick a multimeter on the red wire and any ground to make sure the box has power.

Then underneath the car, hooked up to the transmission vss, there are a couple of jumper connectors. If I had to guess, that's where you'll find the problem.
