95 grand marquis oil pressure guage wont work

Look here, just in front of the oil filter. There will be a wire harness attached.

Never, ever disconnect an oil sensor. It does not lie. You have no oil pressure because your oil pump is not working or no oil in the engine.

No the fuel gauge is mechanical, it could be an issue with the sender unit or the wiring between the sender unit and the gauge

the fuel shutoff is on the right side of the trunk for a 95 marguis ls. my soundsystem tripped mine just press the red button to reset and hopefully that should help you

First off I wouldnt drive your car until you make sure that you have indeed oil pressure and that the gauge is a false reading, driving your car if in fact it has no oil pressure will severly damage your engine, but firstly i would check the oil pressure switch its located on the passenger side of the engine right back from the oil filter make sure the connector is clean and free from oil and corrosion if the connector appears to be in good shape take a paper clip and insert it between the 2 terminals inside the connector your oil pressure gauge should peak at 80 PSI that tells you that your gauge and all related wiring are good and in working condition, secondly remove the oil pressure switch and hook an manual oil pressure gauge up to you engine and start the engine the guage should have a oil pressure reading anywhere from 30 PSI to 55PSI depending on engine temperature if theres oil pressure on your manual gauge replace the oil pressure switch with a new unit, if you still have 0 PSI on your gauge then stop your engine immediatly and start looking at your oil pump and lubricating system for a problem.

the oil sending unit is out.. its the switch that sends the pressure reading to the guage..

sounds like its leaking around the drain plug

At this point I would strongly suggest that you have your mechanic hook a mechanical oil pressure guage to the engine and make absolutlely sure that the pressure is up to manufacturers standards. It may simply be a failing oil pressure sending unit, but, until you know, it could turn out a lot more expensive! Thank you, Dana

look and see if you blew a fuse if not you'll have to remove the cluster and make sure it is plugged in if all this is right the cluster is possibly bad it happens.

Its the intermittant/park relay.
