Low oil pressure light turns on

Is the engine making any kind of irregular noise? I can tell if the engine is the problem if you upload a short video of the engine idling. Also, what weight of oil are you using? Also, can you remove the oil fill cap and look down inside the engine to see how clean it is? What happens is if the oil has not been changed it can caused sludge inside the engine which will clog up the oil pump pickup lastly the oil pump can be bad, it has a pressure relief spring that may have broken causing low oil pressure, Let pull the oil pan off of the engine to look inside the pan and if its clean lets replace the oil pump. Here are instructions in the diagrams below. Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

Yep, it sounds like the oil pump pick up is clogged, or the oil pump relieve spring has broken. Please let us know what happens.
