Okay, the new pump is in. Everything is back to normal. I've diseceted the pump. The plastic impeller is perfectly intact. The motor spins fine. I think the failure is due to the electronics over heating and not obeying the DME control messages. I tried to power the motor from a spare battery but putting power to the positive an negative leads didn't power it on. The connector has four wires: Power (red) Ground (brown) and two signal wires.

I'll try to post the trouble codes tomorrow. Basically it showed zero motor RPM and 170 deg F electronics temp.
