Truck wont turn on!!!

Does it click several times when you turn the key??? LIghts dim or not working??? If so, dead/dying battery.

Yes, lights will work just fine if the starter is bad. Radio will work, power windows/etc will all still work if it's the starter.

If there's no clicking when trying to start it, and all other accessories work, then you either have a bad power lead from battery, bad lead to the solenoid, bad ignition switch box, or bad starter itself. Rare, but on occasion, you can get a bad cell in a battery that only shuts off when under high load. Those can be tough to diagnose.
