Fuel Pump Shut-Off Switch
If the engine cranks but does not start or if you have had a
collision, the fuel pump shut-off switch may have been actuated.
The shut-off switch is a device that automatically stops the flow
of fuel to the engine when your vehicle has been involved in a
collision. The impact does not have to be great for the switch to
be actuated. In many instances, you might not even know that
the switch has been actuated.
For information on how to check and reset the fuel pump
shut-off switch, see Fuel pump shut-off switch in the Index.
