The ignition system is of crucial importance for your Toyota 4Runner, as its main functions are powering on and starting the vehicle. If you want your SUV to provide smooth and reliable performance, you have to keep its ignition system parts in top shape and sensors, switches and relays are no exception. When beginning to fail, all these components will lead to starting troubles. So, if you’re experiencing difficulties when starting your 4Runner, it is recommended to take your SUV to a mechanic to determine the problem and fix it. If you don’t address these issues timely, your vehicle may not be able to start at all.
There are symptoms that are inherent for problems with certain components. For example, if your vehicle suddenly stalls during driving, it may be caused by a malfunctioning ignition relay. Your SUV sometimes may restart when the relay cools off, but when it does overheat, your vehicle will stall again. A clicking sound coming from the starter is also a symptom of a failed starter relay. In case electrical accessories of your vehicle don’t power on after you insert the ignition key, your ignition switch may require replacement. In our catalog of Toyota 4Runner ignition relays, sensors, and switches, you will find everything needed to fix the problems mentioned above and much more.
