Reply to "oil pressure Gauge not working. how can i test it see if gauge or sending unit ?"

Do you have a problem with the oil pressure gauge AND the water temperature gauge?

If that is the case I would closely check the grounding wire that serves the gauges. It is a daisy chain ground circuit that can benefit from having the end of the factory wiring also attached to chassis ground

Of course you would also check the visible wiring on the engine serving both of the sending units

Have you done any recent work on your car that might have disturbed any wiring connectors ?
