If you are asking about an automobile engine, in most cases the oil pump is driven by timing belt, so it operates whenver the engine is running.
Yes, but dont do it as you can do substamtial damage
Your check valve is not holding in the oil pump and allowing the oil to fill the engine. When you start up, the oil pump is trying to empty the engine and excess is pumping out the breather or overflow.
You do not have to prime the pump. Just add the correct amount of oil and start the engine.
Answer oil pressure problemI would think that you need to replace your oil pump or make sure the pan gasket hasn't rotted and fell in the oil pan and is stopping up the pick-up tube.If its not the oil pump then you have a bearing problem,I would start with the oil pump first.Hope this help Ricky B. Yes i would start with the oil pump. But it sounds to me like the dreaded cam bearings.
Good question. I'm looking for a way to prime the pump before initial start-up of a Pontiac 350 that has sat for years. If, I were to have to change the pump, I would be looking at safely removing the oil pan, first
yes it will start but you dont want to start it.
Pack a new oil pump with petroleum jelly. This will create a suction when the pump starts up and suck oil in. The jelly will dissolve in the oil harmlessly.
there is a second oil pressure switch that shuts off the fuel pump if theres not enough oil pressure
you just pump it up
If it doesn't have an oil pump, the engine will seize right after you start it. If this has a 3800 engine (I think it does) the oil pump is mounted to the inside of the front timing cover. The crankshaft passes through the oil pump directly driving the pump, so there's nothing that can break to prevent operation of the oil pump.
You might not be getting enough oil out of the oil pump. Start it up and see if it drips out of the hose every few seconds.
The oil sensor is junk. You MUST replace it. Be sure to put a SMALL amount of sealer on the threads. When you start the engine the oil pump pumps oil up to and in the oil sensor.
