So I see you have changed the oil filter and oil, did you change the EOP sensor?
Automotive Expert
here is complete test procedure for that which you need to start with checking the oil pressure with a hand held gauge to be sure the oil pressure is good then you should check the wires going to the ECM from the EOP sensor and you may try a new OEM sensor from AC Delco.

Ok
Automotive Expert
After all that you may need to have the ECM checked as it could be the problem.
