It's suppose to be a PWM signal to the solenoid. Applying 12 volts to it would basically set it to 100% duty cycle.

I think these are your problems. The SVT will go into limp mode if it does not see a rational road-speed signal within the first 5 seconds of vehicle start. This seems to be your culprit and coincides with no assist because of no road-speed signals at any wheel.
