Error code 551 on a Ford Contour typically indicates a problem with the fuel system, specifically related to the fuel pump or fuel pressure. To fix it, start by checking the fuel pump relay and fuse for any issues. Next, test the fuel pressure with a gauge to ensure it's within the manufacturer's specifications. If the pressure is low, consider replacing the fuel pump or inspecting the fuel filter and lines for clogs or leaks.
