Hey, I have a 2008 Chevy Silverado 1500. I have done a motor swap from a v6 to a v8. After the motor swap the speedo stays at 0mph while the rest of the gauges work. I have a new VSS. Also checked the voltage for the VSS output and it’s good. I don’t know why my speedo doesn’t move. Could it be the stepper motor is bad. However I had tried my other cluster and they all do the same which the speedo doesn’t move. Also gives a bad camshaft sensor whenever it’s a brand new ac delco sensor. Could it be that I have a bad ECM??
