I have a 2013 tradesman with 5.7. The issue I'm having is my truck will click like the selinoid is not engaging.but had test ran and starter,battery, and alternator checked out ok.if I jump start it it will start ok. Any suggestions?

 

What's battery voltage look like? Usually, that's a sign of a failing solenoid in the starter.

 

Check all cables clean and tight.
