As soon as the engine starts turning over, and it works until you turn the engine off.
ClarificationThe oil pump is driven directly off the camshaft or the crankshaft (depending on the manufacturer), and whenever the engine is running, the oil pump pulls oil out of the crankcase and sends pressurized oil through the oil "journals" of the engine.All of the rods, mains and camshaft bearings float on a thin film of pressurized oil. Technically, none of those bearings should ever come in contact with the metal of the crankshaft or camshaft.
If the oil pump STOPS functioning while the engine is running, the bearings mentioned will come in contact with the crankshaft and/or camshaft, and deteriorate and fail in a short time.

All car engines have an oil pump.
There is a hexagonal rod between the oil pump and distributor. As the distributor turns so does the oil pump. The newer DIS engines use a distributor plug that retains the drive gear for the oil pump rod.
Yes all engines have a oil pump, It's in the oil pan.
The 96 series Harley Davidson engines use a twin-gerotor oil pump, instead of the external pump of the other EVO engines. This makes replacing the pump more difficult, requiring professional assistance or at least access to the printed service manual.
The oil pump on most engines that run on gasoline are located in the oil pan. Diesel engines sometimes have two. One in the pan and one on the front of the engine to power the fuel injectors.
there is no oil pressure on a lawn mower it has a splash the oil around inside the engine. There are some small engines with an oil pump. It is mounted inside the engine oil pan.
it is under the fuel pump on the v6 2.8l engines
No, old oil can use synthetic engines
It's the arm/tube that attaches to the pump itself & draws oil from pan & falls of sometimes because is only a press fit on many engines.
No. It is blended for gears not for engines.
Not possible to answer. This car came with several different engines that changed depending on model year. "In the engine" is not the an acceptable answer. On all engines that were in a Stratus, the oil pump is on the front of the crankshaft under the timing chain/belt sprocket.
