Question about 2001 Chevrolet Impala
You have problems somewhere with coil pack or use a, Noid light to make sure everything is firing. Sounds to me like your not firing on all cylinders.

turn the key to the on position a see if you can here a buzzing sound around the fuel tank,if you don't hear a sound then. (be very careful while doing this) with the key off take a fuel line coming from the tank loose,make sure its pointed away from you and turn the key to the on position,see if any gas comes out,if not then your fuel pump is probably bad.

Wow you have replaced a lot of stuff. Lets go back to the Fuel pump. When you replaced it did you replace the hose between the pump and the sending unit. These are common for splitting. Have you hooked up a fuel pressure gauge to check what pressure you have? It should be real close to 13 psi and should raise to at least 18 or 19 when you pinch off the return line.

Have you heard of Noid lights? You unplug the fuel injector and plug these in and they will light up if the injector is getting power. This might give you a better hint. There are also lights that go inbetween the spark plug and wire. Between these two items you may be able to narrow down the problem to a specific system. I believe that your car has a coil pack. Some of these engines have problems with the crank trigger. I believe it is located on the back side of the motor. If you decide to change it, be careful. I have heard of them breaking into two pieces and becoming a big problem.

If this car uses an electrically heated O2 sensor, the heater portion may be bad. If the car has a lot of miles, the O2 sensor may be getting bad also.

I had a similar problem in a 1994 Taurus, and after spending nearly 300$ on ignition parts, it turns out the problem was a bad spark plug wire that cost me 8.88$ to replace.
