You sure a fuse wasn't pulled out when it was desmogged? Double check all your fuses. Measure voltage across them with the truck running. They should all be zero. The emission board provides a ground from what I remember. Unplug each VSV and measure the plug coming to it with your meter. How did you measure 12V last time? Did you measure with your meter across both pins? If the board is not closing the ground path then you will get nothing. Try measuring each pin separately with your other lead on a good ground point in the engine bay. You should measure 12V on one of the pins for all the connectors that supply power to the VSV's. If you don't then you got a power problem with a bad fuse or wiring.
Next check your ground on pin 7 on the board with it connected. One lead on pin 7 and the other on a good ground inside the cab should show ~.6 ohms.
I agree it is a lot of time but I can talk you through this you don't need to take at some where yet unless you are just done with it.
