Did you remove oil sending unit and install a oil pressure gauge in it's place and read it so you can rule out the gauge in the dash and sending unit ? If not, then do it.
Then if you don't have oil pressure. Remove the oil pan and check the oil pump pick-up screen to see if it is stoped up, if it is replace oil pump and screen. If it's not then replace oil pump and screen anyway.
