If the Engine Cranks But Does Not Start or Does Not Start After 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. Fuses Fuses and circuit breakers protect your vehicle's electrical system from overloading. If electrical parts in your vehicle are not working, the system may have been overloaded and blown a fuse or tripped a circuit breaker. Before you replace or repair any electrical parts, check the appropriate fuses or circuit breakers. The following charts tell you which fuses or circuit breakers protect each electrical part of your vehicle. If a fuse blows or a circuit breaker opens a circuit, all the parts of your vehicle that use that circuit will not work. 200
