Either your pump is bad or the relay that controls it is bad. The turbocharger jacket has a thermostat on it. Follow th line that comes from the thermostat to the union point, perhaps six inches away. Unplug it and momentarily ground the female end (the part of line that goes away from thermostat). The pump should run for 20 seconds or so. If it does not, I'd disconnect the pump wires and apply 12 V to see if it is ok. If it runs, then its the relay. The pump should run when you shut off the engine regardless of water temperature.
