So I pulled the connector, and measured the voltage between pins 3 and 5 on the RCM and got 0 V. I then turned the key to the on position and manually closed the gate and that measured with a voltage about 5 volts. My battery is showing just over 12.0 V so if I'm understanding things correctly, this point to the solder joints? There is a bad connection in there somewhere that's acting like a resistor and eating up the voltage supply before it can reach the pump?
