Well, if you say that when he stops the car, but the engine still running (idling) - that "stop engine oil" light comes on, it could mean that the oil pump can no longer maintain the minimum oil pressure to the critical areas of the motor at an idle.
If the light goes out with a higher idle (driving the car) that is a good indication of a worn out motor.
be sure the oil is at the full mark, not below or above the full mark. Make sure the oil and filter are new. The sender units for the oil lights rarely go out - but it is possible.

Could be a faulty oil pressure sender unit or low oil pressure. this could be because of a defective oil pump or worn crank shaft bearings

1999 cadillac deville.. oil light came on and the engine shut its self off


The vehicle has gone into self protection mode. There was no oil pressure (hence the light coming on). Check if the engine oil level is correct, if so, you will have to call your dealer to find the problem. Could be oil pump or maybe just a faulty oil pressure sensor.

Low oil pressure turn off engine comes on when i slow down and stop/ whats causes this?


Could be Several things...in order of severity.

Old, Old oil.
Wrong oil viscosity, or right oil with additive, and/or wrong filter.
Oil pressure sending unit/sensor is bad.
Oil pump worn out.
Worn lifters.
Main crankshaft bearing(s) worn out.

Now that I've raised an eyebrow, it is most likely one of the first three conditions.

1997 Cadillace Deville: My oil pressure light comes on when I am stopped at a redlight and goes off once I give it gas. The Oil Level Sensor AND the Oil Pressure Sending Unit have both been replaced. About...


This problem is caused by a defective oil pressure sending unit on the engine in most cases. The oil pressure sending unit is located on the oil filter adapter housing on the front of the engine. It is hidden a bit behind the front engine mount bracket.

Oil pressure light comes on as I am driving the stop enine light


ok, change the oil to proper viscosity. This happened to me on my 1997 Cadillac Deville. The manual says that when this happens, the oil could be too thick (filled with gunk I suppose). Oil won't flow right when it hasn't been changed for a while.

My 1986 cadillac deville cranks over but wont start what could it be?


It should be either no Spark or no Fuel.
Possible causes: Out of gas, no oil pressure, faulty oil pressure switch, Bad fuel-pump, fuel-pump relay, needs tune-up, defective ignition control module, wrong air/fuel ratio, defective IAC valve or EGR valve.
Other causes: Wrong timing, bad compression, or clogged CAT.

Probably an oil pump, will it still do this if you rev the engine a little while stopped? If not then you have an oil pump that could be failing or hopefully it is the pressure sensor that is off. either way don't chance it

The idle may be to low or the motor is just old and a new set of rod bearings is need with an oilpump to bring the pressure back up.

Overheating,eveything looks ok.


I have a 97 Cadillac Deville with a northstar engine and have replaced it twice so far, so i answer this by experience...i've noticed to my two prior engines that went bad that the normal temp should NOT EXCEED 228 (normal), the red overheating light will come on at 250 and at 260 it will beep and tell you to stop engine - idle engine and will begin to smoke (overheat).

I hope this helps you and anyone else...by the way if your asking why did i replace my engine twice is simply because my cadillac is super clean inside and out, immaculate condition.
