One problem related to fuel delivery has been reported for the 2001 Chevrolet Silverado. The most recently reported issues are listed below.
I have just recently purchased a 2001 Silverado and my gas hand will go to empty and my low fuel light will come on but I will have a full tank of gas. . . If you shake the truck or stomp om the gas pedal it will go back to full and light will go off. . . A friend of mine has a 2002 Silverado and my aunt has a blazer and they all do the same thing.
