Q: I changed my starter relay and tested my starter but my truck still won't crank or start it just turns everything on

Hello, thank you for writing in. The first thing we need to discuss is the testing of starters. Starters are only bench tested typically, which means they hook up a power supply and watch for it to function. What they are not taking into account is that the starter needs to not only spin, but it has to push the over the engine. This is a heavy load, and starters are not tested for it. With that being said, I believe you need to replace the starter. It is not unusual for a vehicle with this many miles on it to experience issues with the unit. The ignition can be tested electrically, as can the starter. For more help resolving the issue, contact our service department to schedule an appointment.
