2013 Ford F150: Where is the starter solenoid?

The Starter needs to be changed. Are you hearing a ticking, but the engine will not engage. IF you tap the starter with a hammer while a friend turns the ignition and it starts when you' re having an issue, there is your answer. This is the first sign off a starter. Check the battery and than the solenoid for a click. you should hear it once and than the starter should engage. Too much clicking is a sign that the solenoids are working put the starter is not. No clicking and it is the solenoids.
