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
Thanks, what are the symptoms of a fail or bad oil pump. What will the car start to perform like or what will be the functioning issues of the vehicle.
if it slow oil pressure you could cause major eng damage so do not grive if suspect there is an 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.
