I'm not sure I understand your post clearly, but if the vacuum pump runs when you turn the key but the door does not lock/unlock, you need to look for vacuum leaks in the lines from the pump to the doors or look for a bad diaphragm in the lock actuator itself. If the pump does not run when you turn the door key, the actuator switch or the wiring from the door to the vacuum module is bad.
