This is a Combination of Both. Replace the Sender first as this is the Cheaper of the two. If not you will need the Oil Pump.

Oil gauge drops low at idle


Low oil pressure at idle can be caused by an engine with worn rod or main bearings due to (usually) high mileage . This however does not mean the engine is still not serviceable as long as the oil pressure is low only at idle. The pressure should at minimum get into the normal range at anything above idle speed.Not much oil pressure is really necessary at LOW speed. At low speed, as long as there is oil getting to the bearings, even at low pressure, you are OK. In a high mileage engine the oil pressure is often low at idle simply because the oil pump is turning slowly and cannot maintain higher pressure between the larger than normal crankshaft and bearing clearances. As speed increases the pump turns faster and supplies more oil and the pressure should go higher. Low pressure as long as it is only at idle is not a problem. However at higher speeds the pressure should be in the normal range. Such a worn engine can benefit from higher viscosity (thicker) oil such as 20W-50 in above freezing weather and 10W-40 in winter. That will increase idle pressure and the thicker oil film maintains a better film between the worn parts

My oil pressure is dropping and at the same time my car is idleing to where it seems like my fuel pump is dying. Are the 2 related. If I step on the gas the oil pressure picks up and the my car gets gas...


Your oil pressure will increase and decrease with the speed of the engine. As long as your oil pressure increases, that's ok. The idle problem could be caused by a dirty fuel or air filter. I would start with replacing the fuel filter and check the condition of the air filter.

2000 Jeep Grand Cherokee Limited oil pressure gauge is dropping to 0 when idling in gear. What is wrong and what do I have to do to ix it?


First check the oil level and top up as necessary. If the oil pressure is at 0 , then it would very quickly sieze the engine, that not being the case, it sounds like you need to replace the oil pressure switch/sensor, which will be mounted either on the engine block or on the oil filter housing. Hope this helps

Oil pressure gauge reads normal when first starts. as it warms up, gauge goes to zero. If I rev engine, gauge goes back to normal.


Two things...when it reads zero, is there any engine noise (tapping or knocking)? After you rev the engine does the pressure read normal at idle and function normally, or does it go back down? Either way, you should not drive the vehicle 'till you have a mechanical gauge (yours is electro-mechanical) put on there and the actual pressure is tested. The condition may be a bad sending unit, a bad bearing or possible obstructed oil pump screen. The repair is obviously different for each one and the price is as well.

1999 jeep grand cherokee losing oil pressure


This is not necessarily an issue, but normal physics. I suggest remove your transducer and test with an external, known good, gauge.... Be sure the vehicle is at normal operating temprature....that will give the lowest pressure reading, as compared to cold engine.
