Check your fuel pressure, and or injectors. You may have too much fuel getting into the engine causing it to burn rich and overheat the converters.

a crank position sensor could be bad or your cam position sensor could be bad

I would look into the catalytic converter too. I just went through this same symptoms. The engine will sputter and run rough. Drive a few miles at night and see if the front exhaust pipe, right behind the radiator, is glowing. That keyed me in. There is a special service to fix certain models for 01 and 02 which is sort of a recall but not exactly. The dealer just fixed it for free. The chevy customer service number is 1-800-630-2438, they can check and see if you Vin number is on the recall. Your local dealer may not know about it so call the number first and make sure you have the Vin, at least the last 8 of it, when you call.

The s10 have a fuel shut off relay to shut off fuel supply in case of an accident. They also have a anti-theft system that prevents fuel in case of theft.Pull the fuel line off and crank the engine to see if you get fuel. Sorry I can't be of more help but without hands on vehicle it is hard to tell.Also your fuel pump maybe sounding like it is pumping. In other words it may be running but not pumping fuel it mat have a ruptured diaphragm in the pump.The pump is running but not pumping fuel. Pull the fuel line off at the fuel filter and turn on ignmition or crank the engine you should have about 50PSI coming out.If you don't install new fuel pump.These vehicles are common for this problem the fuel pump runs but does not pump fuel or not enough pressure these vehicle require 57 PSI to start if it has less than 51PSI it will not start unless you use starting fluid then it will run.It will run with less fuel pressure it will just not start with less than 57PSI.

Hope this helps

Hi stevie, your Impala probably has a defective sensor, often called a "switch" that senses the oil pressure. The oil light and chime is a result from a false signal from the bad sensor.
But one cannot take a chance. If the sensor is acting properly, and pressure is low, it could really damage your engine to have low oil pressure and oil not pumping properly. Have it checked now. A new sensor should cost about 60 dollars & takes only a few minutes to install.

Good luck. i hope this helps. Please rate me a FixYa.
