I have a 99 ZR2 S-10 with a 5 speed tranny with 30000 miles. When I first start it up the ABS light comes on and stays on,and the speedometer or the odometer does not work. Drive it down the road for about 5 miles or so and the ABS light will go out and the speedometer and odometer will start to work. Did you ever hear such a thing? Any one have any ideas on what causes this weird thing or what can be done to fix this problem, thanks

Check the vehicle speed sensor. This is used by the speedometer, ABS system for these systems to work properly. Take a look at it and make sure the connections are good and clean. If they are, chances are the sensor needs to be replaced.
