@exp500 excellent suggestion!
Looked up P0230 in FSM. It's basically what I thought it would be, the control circuit for the relay (not power side). If the relay fails the PCM would notice no current flowing through the circuit and trip the code.
I completely tore down this pump. WOW is it a piece of art. VERY well built. Took the armature out of the pump motor. Trying to assess the windings. Find something odd but not sure if it's an issue. Most of the windings are 0.6 Ohms but a couple are just over 1 Ohm.
