My car stalled after being parked on a slope. I checked the lights and it said the oil was low. This is something I check religiously. After putting in oil the light is still on. My friend said it could be the oil pump. I can't start it without it wanting to stall. What should I do?
Replace your oil pressure sending unit. many have a low pressure shut off feature that will prevent engine from running. Also, don't check oil on a hill, you will always get a false reading. If the problem continues you will need to have a mechanical gauge put on the engine to verify actual oil pressure. then plan a repair according to those results.

The oil pressure warning light is designed to illuminate any time the oil pressure is too low (below a pre-set engineering-specification). Low oil pressure can be caused by an oil level that is too low, a faulty oil pump or worn out engine bearings. The light could also potentially illuminate if the engine idle speed is excessively low (near stalling condition) due to the slow rate of pump rotation. There is also the possibility that a failure in the oil pressure warning circuit is causing the light to illuminate inappropriately; this could be the result of a failed oil pressure sensor or other wiring issue. Because the other symptom present is an engine stall (shuts off) condition, I'd recommend inspecting for a mechanical issue first. Ensure the oil level is correct, then attempt to turn the engine over by hand using a large ratchet on the center crankshaft pulley bolt; if the engine can be rotated it was not stalled out by a seized condition (which could be caused by a lack of oil pressure). If the engine runs but idles low, I'd suggest raising the RPM to see if the light goes away and prevents the stalling-out. If everything appears OK with a raised idle then the idle control system should be inspected. On the other hand if the light remains on, a mechanical oil pressure gauge should be installed to the oil pressure test port (near the oil filter) to confirm whether or not the oil pump is producing adequate oil pressure.

Im not fully conversant with Turbos , but I would hazard a guess from memory that there is an oil feed from the engine to the turbo to lubricate it. I would think that the oil sump in the turbo has a seal at one or both ends. When the car is level, the oil doesn't reach the level of the oil seal, and therefore doesn't leak. When the car is on a slope, the oil will level itself out and probably be above the oil seal and then it leaks. Check if the leak occurs only when the car is pointing uphill or downhill. It may give you an idea as to which end seal is leaking.
This is the "Low Oil Pressure Warning" light. It is RED for a reason! When this light (or any RED warning light for that matter) comes on, pull over and shut the engine OFF at once. Allowing the engine to run with insufficient oil pressure can cause a catastrophic failure in mere seconds. Such a failure can cost thousands of dollars to repair. This warning is most often the result of a very low oil level as indicated when checking on the oil dipstick. The engine oil level should be maintained as close to the "full" mark as possible - without exceeding it. Oil should never be allowed to drop below the "low" mark on the dipstick. If the oil level is shown to be between full and low, the light is probably coming on as a result of a faulty oil pump (the oil level should be checked with the vehicle parked on level ground, with the engine OFF). A faulty oil pump is unable to pump the oil with enough pressure to reach all the moving parts of the engine that require lubrication. Without proper lubrication, connected moving parts heat up, expand and seize. Moving parts are expected to move - not be prevented from moving. If your engine shut down, it may be the result of some of the internal parts seizing. Hopefully, this is not the case. Check the oil level and top off as needed to bring the level up and attempt to start the engine and have the vehicle checked by a trusted mechanic. Good luck!
Your problem is indicitive of a rear engine main crank seal failure and possible excessive oil in the sump. Check oil level and make sure it is on the mark and not over it.
It may be the oil pump. If the gauge is going up when the rpms increase it's probably not the gauge or pressure switch. If the computer senses the oil pressure is low it will shut the vehicle off to try to save it's self from catastrophic failure. Also it may start cranking longer before starting. Thats it building oil pressure before the computer will let it start. Make sure oil is full, clean & thick.
Either your power brake assist booster has a bad check valve
in it causing a huge vacuum leak when you step on the brake (Vacuum
leaks lean out the fuel/air mixture causing stalling) or you have an
'engine protect' sensor that kills the ignition/fuel pump when the oil
level's too low and it's either got crud in it from running the oil too
low or has otherwise malfunctioned.
CHECK OIL LEVEL FIRST.IF LOOKS OKAY HAVE OIL PRESSURE CHECKED IF OIL PRESSURE GOOD.YOUR OIL FILTER AND OIL HAS BEEN CHANGED AND OIL NOT TOO HEAVY OR THICK AND YOU ARE USING THE RIGHT OIL VISCOSITY.YOU COULD HAVE A FAULTY OIL PRESSURE SWITCH.IF CAR STALLING IN MOTION YOUR FUEL FILTER STOPPED UP OR FUEL PUMP GOING BAD.
The oil pump may be going out - the light indicates the pressure is below the proper level and when you step on the gas it spins faster/raises the pressure back up to an acceptable level.
This is something to get checked RIGHT AWAY, as these cars have a history of engine failure....possibly due to low oil pressure.
Check the oil level. The low oil sensor will disable the ignition if more than a quart low. If you have not checked your oil in the last 1600 miles, its past time to do so. Check oil often.
