a Collision
The 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 triggered. The shut-off
switch is a device that stops the fuel pump
when your vehicle has been involved in a
substantial jolt.
For information on how to check and reset the
fuel pump shut-off switch, see Fuel pump shut-off
switch in the Index.
