Question about 2003 Chevrolet Cavalier
The car does start and drive but it feels very sluggish as though there is no compression. I am hoping this can be solved with just a oil pump but would like the input of the community with hopes there is someone out there who may be experienced in this type of issue and either confirm my suspicions or offer me some advice as to where I need to go from here. This is our only transportation right now so it has to be fixed pretty quickly.

Highly doubtful that a pump will fix a 0 oil pressure problem. This sounds more like worn bearings. Have a shop do a pressurized oil leakdown test before replacing the oil pump. If the bearings pass the test, then try a pump.

SOURCE: Fluctuating oil pressure gauge.
Two quarts is about half the capacity. The pump was probably starved of lubrication and is failing.
If that's not expensive enough, you may now have a problem with a damaged engine. You may want to just put that money into a new vehicle.
I don't think the car would have enough power in its present condition to get high enough to reach a cliff, and driving it into a lake would not be environmentally sound. Besides, the fine would not be worth it.
The cheapest and easiest maintainance that anyone can do on a car to avoid expensive repairs is still checking the oil ever 1000 miles (filling if necessary!) and changing it every 3000.

In some cases where the oil is not changed properly, the oil pump screen maybe plugging or your oil filter is defective. Fram is a good filter. If there is no problem found, replace the pressure sensor.

dont run it anymore!!!
check oil is reaching the rockers & that there are no blocked feeed holes !
the pump may have been fitted too loose or the gaket is not sealing creating a pressure drop!
it may have some of the old bearing material enter the gallery,s & or the pump!
good luck Cheers Rob

i would find and replace the oil pressure sending unit although oil pressure is ok the computer needs to know or else it will shut down engine and it seems like your oil pres. sending unit is starting to stick.
