is the Oil Pump located in the oil pan or driven directly by the crankshaft. on 1994 Lexus ES300

How much will I expect to pay for labor and what else could make the oil warning light come on every time I drive the vehicle; it will come on for a few minutes then go off repeatedly only while driving not while sitting in idling mode.

seek a manual oil pressure test, it could be just a sending unit issue

I have a 1994 Lexus ES300. There is also a slight knock in the engine, along with a tapping sound. I need to know where is the oil pump located on this vehicle? Can it be located through the oil pan or located in the crankshaft.
