Gotta use a tech 2 scan the Fuel pump control module and find out what code it has and why it's detecting it. The code you mentioned is just a flag code sent to the PCM by the fuel pump control module to turn on the MIL and alert the driver to a problem

 

im a gm driveability tech and the p069e if fuel pump module request illumiation, i bleieve that year has a recall for the modules getting water in them or simply the module goes bad thats the only real problems i recall seeing
