The starter solenoid in your vehicle is the switch that provides power from the battery to the starter motor, which turns over the engine and starts your vehicle. When the solenoid goes out, you can’t start your car and are typically left stranded. Solenoids aren’t difficult to install, but if your car won’t start, you need a way to start the truck one time to get it to the store. This is a dangerous procedure and will cause a shock–but if you have to do it, it can be done.
Pop the hood and locate the starter solenoid. It’s typically on the fender well of the vehicle, near the battery.
