That pilot is heating a thermopile right? If so your thermopile is bad. Most thermopiles are closer to 400-600mv when fully heated which opens the MV part of the gas valve. The flame sense rod would only come into question when the burner actually lights and then quits.
Have you checked to see that you have 24 volts to the flame sense rod? Is the flame sense rod heated by the the actual pilot flame?
Im not real familiar with this unit. But usually a flame sense rod is in direct contact with the burner flame. Not the pilot. Does the rod that the pilot is heating have wires coming out of it or just a cappilary line?
It would really help also if you could attach a couple of pictures of the pilot, igniter and flame sense rod.
