Could be a faulty pressure sensor. The pressure sensor on many GM vehicles is located on top of the fuel tank attached to the fuel pump/sending unit assembly. It can be changed with the tank in place if you can get your fingers on it. Unplug the wire harness from it and wiggle the sensor straight up and out.
