no special tuning, speedometer quick working, changed speed sensor, still didn't work, checked at the sensor with key on and had no 5volts , checked where it comes out of ECM, nothing there, wire going to ECM is good, wondering if ECM is the problem

My gueass you are checking road speed sensor located on tranny rear? Should be no voltage to the sensor, sensor is magnetic, create pulses.
Or you have problem with engine speed sensor?
