Inertia Fuel Shutoff (IFS) Switch
WARNING: This page is about a different car, the 1996 Mercury Villager and 1995 Mercury Villager. However, it is still accessible from the selected car via links, so may be relevant.
Ensure ignition is off. Inertia switch is located behind bottom of left cowl panel. See Figure in THEORY/OPERATION article.
NOTE:
In closed position, reset button can be depressed an additional 1/16" against spring. This is normal and does not affect IFS switch operation.
Push down on reset button to ensure switch is closed. Measure resistance between terminals on switch. If resistance is 5 ohms or less, switch is okay. If resistance is greater than 5 ohms, replace switch.
