Make sure the small, 1-wire sensor is connected near the back of the pump. It's a pressure sensor that tells the engine to idle-up to make steering easier.

Otherwise, check your fluid level, condition, and for any leaks. Past that I'd look into a stiff steering system (u-joints, bound rack, bound upper strut mounts, etc).

The o-rings on the supply port can start to fail and allow air into the pump. You might only notice the issue at idle. There are plenty of threads on it.
