I pulled the speed sensor it looked ok. Sensor still might be bad. Wish I had one to try. For the speed gauge and rpm, when I turn key on the two gauges cycles back and forth showing it works I guess. I thought it be weard that my oil gauge and pressure sending unit, fuel and sending unit , temp gauge give out the same time. All gauges work fine now after replacing them. Just the speed gauge left to fix. Like to have a speed sensor to try to see if that's the trouble.
