Wm.Lewallen: I didn't say anything about a previous owner. I have owned the car 10 years and 110k miles and I never had this problem before, it just started doing it lately so I doubt if the valves are in wrong.
I will try checking the valves as you suggested but how do I do this? Is there a diaphram in the pump that might be leaking and can that it replaced? Are these valves or diaphram available as repair parts or do I have to replace the entire pump?
