Where is the Fuel Relay located on a 1993 Lincoln Mark 8?

The fuel relay location on a 1993 Lincoln Mark VIII isn't standardized like a fuse box. It's usually within the Power Distribution Box (PDB), sometimes called a fuse box, but *not* in a readily accessible area labeled "Fuel Relay." You'll likely need to consult a wiring diagram specific to your 1993 Lincoln Mark VIII.

To find it, you should:

1. Obtain a wiring diagram: A repair manual (Chilton's or Haynes) or a digital version from a site like Mitchell 1 (subscription required) will be your best bet. These diagrams show the relay locations and their associated circuits.

2. Locate the Power Distribution Box (PDB): This is often under the hood, but it could be in the passenger compartment, depending on the Mark VIII's trim level.

3. Identify the Fuel Pump Relay: Once you have the diagram, find the symbol for the fuel pump relay. The diagram will indicate its location within the PDB. Look for markings on the relays themselves, though they might not be clearly labelled "Fuel Pump." You might see numbers or codes that correspond to the diagram.

4. Consider the relay's function: If you cannot visually identify it, you can try using a multimeter to test the relays' power output while someone cycles the ignition switch to see which one activates the fuel pump circuit. This is *only* recommended if you are comfortable working with car electrical systems and understand safety precautions.

Caution: Working with car electrical systems carries a risk of electric shock. If you're uncomfortable with this procedure, take your vehicle to a qualified mechanic.
