My truck won’t turn on?

Sounds like a loss of electrical power, such as with a battery that is unable to crank the engine. Have the battery checked first for state of charge and the ability to sustain a load. Once you have a known good battery installed, you can recheck component operation. Too many possible causes of concern to suggest from here; seek professional guidance near you.
