how can i find out if my oil pump is bad on 2004 Suzuki Verona

i am losing oil but cannot see oil spots under my car. oil sending unit was replaced and now i am told my valve cover gasket and oil pan gasket are both leaking. someone said this could be an oil pump pressure problem. is there a way to determine whether the oil pump is working correctly before letting them fix the gaskets? The oil pump is in the engine.

Early Verona's are bad about premature piston,ring,cylinder wear. If you are under 100,000 miles you need to take all your concerns to you nearest Suzuki dealer. You have a 100,000/ 7yr power train warranty that covers internal engine,trans seals and gaskets.

What are the symptoms you are having? Is the oil pressure light coming on? Is the oil level low? if so, how much oil do you need to add and after driving how many miles? I have some advice, but I need to know exactly what is happening first.
adding about a quart every 500 miles. the oil was not on. only the check engine light. i lose a little power, but not too much.
I have 2004 suzuki verona and the oil light is flickering and it acts like it wants to stall. I changed the oil but it still happens. I was told a relay is involved in the pump system, where is this relay located?
