How do you change low oil level sensor on 95 caprice w/350 LT1?

I use quality oil and do my own oil change but the low oil level light is on more than off. Now I have had trouble starting the car. I was told that the sensor will cut the fuel pump off. Is it as easy to change as doing an oil change?|||it should be easy on our caprice its by the oil filter but i'll send you to our trusty online repair manual, trouble shooting guide and componet locator ..................autozone.com|||I believe that to be an oil pressure not level sensor. You best get things checked out before you fry the engine.
