To find it, you'll need to consult your owner's manual. It will have a diagram showing the location of all fuses and relays, and usually identifies the fuel pump relay specifically.
If you don't have the owner's manual, you can try:
* Online resources: Search online for "1994 Mercury Sable fuel pump relay location" along with your specific engine size (e.g., 3.0L, 3.8L). This might lead you to forums or repair manuals with pictures.
* Repair manual: A Haynes or Chilton repair manual for your specific year and model will definitively show you the location.
* Auto parts store: A local auto parts store (like AutoZone, Advance Auto Parts, etc.) can likely access diagrams or provide assistance based on your vehicle information.
Important Note: Before working with any electrical components, always disconnect the negative (-) battery terminal to prevent accidental short circuits.
