Fuel delivery is controlled electronically through the fuel pump relay and the computer system. To stop fuel flow, you'd need to either:
* Disconnect the fuel pump relay: This is the most reliable way to cut off fuel supply. The location of this relay varies slightly depending on the exact model of your Tempo, but it's typically found in the under-hood fuse box. You'll need to consult your owner's manual or a wiring diagram to locate it precisely. Disconnecting this relay will prevent the fuel pump from operating.
* Disconnect the fuel pump's electrical connector: This is a more involved process requiring access to the fuel pump itself, usually located in the fuel tank. This isn't recommended unless you're familiar with fuel system work, as it involves working with flammable components.
Keep in mind that interrupting the fuel system should only be done by someone who is familiar with automotive systems. Incorrectly handling fuel system components can lead to damage and potentially dangerous situations. If you're not comfortable with this, it's best to consult a qualified mechanic.
