When engine is not running, turning the steering wheel would cause fliuds to be pushed out of the reservoir.
After starting the engine if the reservoir keeps foaming then either the fluid supply hose to the power steering pump inlet is leaking or you have a bad pump.
After sitting for extended period of time and the weather, the pump vanes could be stuck so you need to warm it up a bit and try again.
Jack up vehicle and keep engine running, make full turns of the steering from right to left a few times, keeping it at full turns for a split second before returning.
