I have a 92 honda accord lx the oil light starting blinking so I change the oil pressure switch and still was blinking then I change the oil pump an it's still blinking I don't know what to do no anybody ever have this problem help please thanks

 

Put a pressure gauge in the port and verify what the pressure is?

Check the wire from the sensor and be sure it is not "rubbing" somewhere.

We are going to assume the oil is at the proper level.
