On that style of IFS (Inertia Fuel Shutoff), the button is always red. The older, larger style has an exposed white "T" button.

Inertia Switch....just some FYI
2
I took some pictures for Deathmonkey, to show him where the intertia switch is on a 93 model year Bronco. We determined it wasn't his inertia switch, unfortunately he has more issues. But since i took the pictures, i figured i would post them for some other people and the newbies.
Step 1:
Remove passenger side kick-panel: (thanks to the P.O. mine doesn't require actually removing any interior screws)

Step 2:
Locate the switch (on mine the button is red, but it may be yellow or another color) push the switch down to reset it (push down, and it holds down)
![]()
The inertia switch is the the black thing with the red top next to that ball of wiring under my kick panel.
The inertia switch cuts power to the fuel pump in case you are ever in an accident. This way your not pumping fuel all over the place. These things do go bad from time to time.
I think previous to 1991 the inertia switch is located to the left of the brake pedal on the driver's side.
I know most of the experienced guys know where this is at, but some of the less experienced guys, and the new people ask about it quite often, figured i would post it.

Right - don't beat on the IFS. That's why the slot is there.
