its the main relay. it turns on the fuel pump. go to the dealer and order a new one. its located under the dash. its gonna be held by one bolt to the body by a metal arm most likley. its the black box with a brown peice on one side with the wires going in to it. sometime they say main relay on one side (or sumthin like that) most of the time these are a bitch to get to... so have fun lol
