What's wrong, in plain English
In some of these vehicles, a leftover piece of plastic from manufacturing may be stuck in the fuel pump's nozzle. This can block the nozzle and keep enough fuel from reaching the engine. When that happens, the engine may not get the fuel it needs to keep running. GM will have dealers replace the fuel pump module to fix the problem, at no cost to owners.
