    Have you measured the oil pressure with a mechanical gauge. The factory oil pressure gauges are very inaccurate.

Oil pump failures are very rare. They usually work or they don' is not likely that you have an oil pump that is "going" bad. Most problems with low oil pressure are caused by worn-out main and/or cam bearings. (We are talking about a 19-year old engine here.)

Anyway, to replace the oil pump. remove your fan and fan shroud to provide clearance. Remove your distributor cap to prevent damage to the distributor. Remove the through bolts in the engine mounts and raise and support the engine. (This is easiest with an engine lifting fixture.) Remove the oil pan. Remove the oil pump. Reverse procedure to install.

5.2L and 5.9L Engines
It is necessary to remove the oil pan, and to remove the oil pump from the rear main bearing cap to service the oil pump.

  1. Drain the engine oil and remove the oil pan.
  2. Remove the oil pump mounting bolts and remove the oil pump from the rear main bearing cap.

To install:
  1. Install the pump and tighten the cover bolts to 95 inch lbs. (11 Nm).
  2. Prime the oil pump before installation by filling the rotor cavity with engine oil. Install the oil pump on the engine and tighten attaching bolts to 30 ft. lbs. (41 Nm).
  3. Install the oil pan.
  4. Fill the engine with the proper grade motor oil. Start the engine and check for leaks.

Wont Start/ Stay running

Oh man, I had the same problem with a Chev Baretta. Domestic autos of those years have so many redundant systems to prevent ruining the engine. In the case of Chev, low oil pressure would shut off the fuel pump. But a bad oil pressure sensor will do the same thing, as it's giving a false pressure reading. Best advice is to get your hands on a Chiltons/Haynes repair manual for your truck and follow the trouble shooting section. Best of luck. (After much frustration I did get that sensor replaced. Drove great until the fuel pump itself quit. I left that repair to someone else. I'm not into self-immolation.)

2003 Dodge Neon Check Oil light wont go off. Car has oil-full, and just put in new Sensor.

Do you mean the oil level sensor was replaced, or do you mean the oil pressure sending unit was replaced?
If it was the oil pressure sensor was replaced, then I would look into an oil pump going bad, not supplying enough pressure to the oil pressure sensor. This can be tested by putting an oil pressure gauge into where the oil pressure sensor normally goes, bypassing the circuitry that leads to the dash light for the oil pressure.

If it was the oil level sensor, then check for bad wiring.

Were is the oil pressure sensor located on a 1992 dodge dakota

It is located behind the breather, on the passenger side of the distributor. If you are having low oil pressure I'll give you a tip. You can change the sensor, but if that doesn't work, then the problem very likely could be that, dodge dakotas are notorious for a buildup of sludge on the screen of the oil pump, which blocks the flow of oil. If you are going to drop the oil pan to address this you may as well put a new oil pump in while you are at it. They are 30-50 dollars. If you can do it yourself, the whole operation should cost less than 100 dollars, if you take it to a garage, you better have a fat wallet.
