The fuel pump will not stay on if you loose oil pressure. This is why it is shutting off. The loss of oil pressure may be from bad crankshaft bearings or camshaft bearings. The engine oil pan should be removed and the oil pump needs to be checked to ensure that you put in the pick up tube seal to the pump and connected the pump to the block. Then remove at least one main bearing cap and inspect the bearings for excessive wear and crankshaft damage. If you need some help with this, consider YourMechanic, as a certified technician can help diagnose the issue with your oil pressure firsthand and help you fix it accordingly.

Best Answer. Hot at idle 35-38 psi at 700 rpm, 1500 rpm 55 psi stable, at 2200 rpm 60 psi new oil pump and the Engine is a 5.3 B code Engine with 237000 miles. Kenneth P. 25 people think this is helpful.
Best Answer. Warmed up oil pressure would idle at like 20, 25 lbs, up to 40-60 lbs. when rpms are up. If you think you have a oil pressure issue, first take out the oil pressure sending unit.
Oil Level Is Too Low
The oil level dropping below the minimum dipstick line is one of the most common causes of low oil pressure. This can happen at any time, even if you`ve recently had an oil change. Over time, engines burn oil more quickly. This is due to piston rings wearing, seals leaking, and so on.
Oil pressure sensor socket 1-1/16.
Capacity: 8 quarts (with filter).
The ideal oil pressure varies depending on the car brand and model, but generally, the ideal oil pressure is between 25-65 PSI.
When the oil pressure is low, it indicates something is not working properly. It also means there likely is not enough lubricant moving through the system. Keep in mind that lubricant starvation will lead to metal-to-metal contact and machine failure.
Without sufficient oil pressure, your car`s engine will operate with decreased lubrication and increased friction resulting in more heat. Engine overheating can be a complex issue. While it doesn`t always mean low engine oil pressure, low engine oil pressure can lead to an overheating engine.
An oil filter obstruction or blockage can also cause oil pressure to suffer. Oil filters include pressure relief valves. If this valve is damaged, oil will easily pass right through, reducing pressure. It may go without saying, but it is important to also change the oil filter with each oil change.
The engine oil pressure sensor, also known as the oil pressure switch or oil pressure sending unit, is a small component installed between the oil filter and your car`s oil pan. The sensor plays a vital role in making sure your engine functions well.
Code P0521 is a generic OBDII fault code that indicates an oil pressure issue or problems with your oil pressure sensor.
Capacity: 6 quarts (with filter). After refill check oil level.
If your 2022 Silverado is powered by a 5.3-liter V8 engine, it`s important to use SAE 0W-20 viscosity grade motor oil.
One common problem seen in the 5.3-liter engine is a failure of the valve cover to seal, which can cause heavy oil burn. Depending on the wear-and-tear on your vehicles, you may be able to get away with having the rings cleaned and getting a replacement valve cover that will seal again.
Oil pressure is measured in PSI and the perfect amount of oil pressure varies depending on what brand and model car you own. In general, if the pressure is below 20 PSI or under the normal range on the gauge it requires your immediate attention.
The oil level dropping below the minimum dipstick line is one of the most common reasons behind low engine oil pressure. Your car`s engine oil level may be low due to an overdue oil change, an oil leak, or wear and tear. Without sufficient oil, the oil pump will not be able to generate enough pressure.
All 5.3 with DoD have that screen.
a worn or failing pump will cause a loss of oil pressure.
The oil detection sensor works by measuring the level of light. An LED inside the device shines light onto a photoelectric cell. When oil touches the sensing probe it deflects some of the light, activating the unit.
Engines can work without oil, but the effect is so damaging they are only capable of running for less than 30 minutes until failing – and in most cases, it`s a lot quicker than that.
The oil pressure is reading 0. It does not need oil. Oil pressure in a vehicle can still be at zero even if it is full of oil. The oil pressure is developed by the oil pump located inside the engine.
For oil to reach the oil pressure sensor, the oil has to pass through an AFM oil filter screen. This hidden screen is a small filter positioned below the oil pressure sensor.
If your oil filter needs replaced, the car will not accelerate as well as it normally would, and the accelerator may feel as though it isn`t working properly. The engine will run, but not as well as it should. Continuing to drive a vehicle like this can damage essential parts of the engine.
The oil pressure sensor monitors the performance of the oil pump and sends this information to the engine control unit (ECU) on computer-controlled vehicles or directly to the oil pressure gauge on your instrument cluster for non (ECU) equipped vehicles.
