Ignition Switch Replacement
How to Replace an Ignition SwitchYour vehicle’s ignition switch is an important component in the electrical system. One must keep in mind, the actual ignition switch is not the tumbler where the key is placed but rather, an electrical switch located on the vehicle’s steering column which is connected to the tumbler through a steel rod or other device. When you turn the key to the start position, power runs through the switch to many electrical components such as the starter, fuel pump, computer, ignition system and other items which allow the vehicle to start. When returned to the run position, power stops to the starter and continues to all the other components which are needed.Although the ignition switch will provide many years and miles of trouble free service, they can go bad. Most commonly, the switch will short out internally and one or many functions will no longer work. For example, in the start position, the engine starts. However, as soon as the key is returned to the run position, the engine stalls. Other items can include problems with the fuel pump, ignition system and other electrical items.This can be a difficult job to complete, and some may feel it should be handled by a professional. However, if you are confident in your mechanical abilities, the following are general directions for replacing an ignition switch.
