Before replacing the oil pump, please do a mechanical oil pressure test to verify the oil pump is failing. Get the pressure specs for your engine, to verify the pump is failing. Your switch may be failing causing this concern and not the pump. IS the oil level at the proper level? These engines have an issue with the "pan" that is bolted to the lower side of the intake manifold. If your engine is using oil, and you can't find any leaks, this gasket has failed.

Okay What it means is that the oil in your car is either low in level or the oil pressure at low revolutions is low. I highly recommend you to stop driving the car when this happen because you can internally damage the engine with a low oil or a low pressure of oil. Check the oil level first..make sure level is fine and oil looks good. Black and burned oil will give you a low oil pressure as well. If it happen that your car need a oil change. Make sure you get it done and see if the problem goes away. Very rarely oils pressure sensor goes bad but if oil is new and level is fine you can take the oil pressure sensor and connect a tester for a oil pressure. If this is not under the manufacturer specifications.. oil pump is worn out and you have to replace it for a new one.
Good luck and don't forget to rte me. Thanks

If the valve lifters are quiet you most likely have oil pressure even with gauge showing "0".Sounds like the oil pressure switch going bad.I would try that first.

I would stop driving it right away and test the oil pressure with a gauge. If at an idle when its cool you don't hit 30-40 psi....change the oil pump. The knocking is probably your main bearings. While your installing a new oil pump, put new mains in.

Oil Pressure gauge drops to 0 and then goes back up


You may have a defective oil sender or oil pump or the wire is loose. Why did you replace the sender and pump. If this was going on before this you couple have an engine issue. Take it in before it destroys the engine. Chrysler/Dodge has has lots of issues with oiling problems.

Come to stop 99 Ram oil pressure drops to 0 check gauges light.


Change the oil! The 318Cu in V8 (5.2 liter) engine has a problem with sludge build up on the oil pump pickup tube screen. This engine requires oil changes at or before 3500 miles with a high detergent oil.

Losing Oil Pressure in Dodge Ram


I have a 1999 dodge ram with a 5.9liter. Come to a stop and bam no pressure. Replaced sending unit twice. First after market, then mopar. Problem is still there. Replaced pump. Problem was still there. So I talked to tons of dodge mechanics, and this is the real problem. Who ever said that these engines are none for sludge is just reall really stupid. BOTTOM LINE ON THAT FACT. Sludge comes from neglect...
Dodges oil pump makes 8-10 Psi at idle. Always mechanically test that no MATTER what. But the sending unit needs 12-14 psi to read it. So what happens is the engine warms up, and the oil thins. Then you come to a stop, and rpms are low, and your not producing enough psi for the sending unit to read it. So your truck is fine. But if the chime is getting to you. Install a high volume pump. I returned the stock one, and got the high volume pump. I will bet if you change your oil every 3,000 miles you will not see sludge at all. If your dodge has high miles replace valve cover gaskets, becauce the high volume pump may cause the gaskets to leak. Whoever said ther none for sludge just has no love for a dodge, or is a moron mechanic that is stuck in his ways. High volume pump is the fix $85.00 plus pan gasket. If you have a 4x4 you can do it yourself. Drop the starter. Remove torque converter cover. With a 13mm socket with a variety of extentions, and removing a dozen bolts. Do it yourselfer will complete it in 4 hours....

Oil pressure gauge drops to zero when stopped


The Oil Pressure switch is notorious for going bad on Dodge truck. I recently change out my oil pump on a 5.2 L engine only to find that I had a faulty switch. The switch for a 5.2L is only 16.99 at autozone and is less time consumming than replacing the oil pump.
