I have a 93 S10 pickup, 2wd 2.5.
The speedometer and the odometer haven't worked since I got the truck. I put in a new speed sensor today and it didn't fix it. I pulled the gauge cluster and jumped the speedo pin to ground and got a reading, so I know the needle works, I'm just not getting any signal from the sensor. I checked voltage at the sensor and didn't have anything. Checked the wires from it to the fire wall and they looked good. What am I missing? I'd appreciate any help.
Thanks,
Jon

cable driven speedo?

Where do the wires for it run from inside the cab? I can see them from the firewall to the sensor, but not under the dash. If I knew where to trace I could trace. Are there any other things it could be?
Thanks,
Jon

could be lots of things from a pinched wire to a bad ecm/pcm circut, how does the cv ring look? chewed up or nice?

Have you taken a look at the DRAC module?

No I haven't...where/what is is?

The DRAC module is attached to your ECM under the dash. Essentially it converts the signal from your VSS to work with your speedo

Is there a way to test it without replacing it?

You can take it apart and meter everything in it based on the coding of the caps, resistors, et-al
