Fuse Links
Fuse links are circuit protectors that are part of
the wiring harness for some electrical equipment.
These, like fuses, open when the circuit lead
exceeds their amperage rating. Fuse links may be
purchased from your Ford or Lincoln-Mercury
dealer. See the following charts to find out
which electrical parts are protected by a fuse
link.
If the Engine Cranks but Does
Not Start or Does Not Start After
a Collision
Fuel System Shut-off Switch
If the engine cranks but does not start or does
not start after a collision, the fuel system shut-off
switch may have been activated. The shut-off
switch is a device intended to stop the fuel
system when your vehicle has been involved in
a substantial jolt.
Once the shut-off switch is activated, you must
reset the switch by hand before you can start
your vehicle. The switch is on the left side of the
trunk.
