The negative voltage would seem to indicate that there is a problem because all of this is on the primary side of the power supply and there are no negative voltage produced there.
The base of the transistor needs to be pulled up. The 150k resistor should be charging the cap and driving the base higher. Confirm that it's within tolerance and that you have approximately 12v on the end that's not connected to the base of the transistor.
