I have a 99 ford ranger that won't start. What could be wrong with it?

None of the lights work, lock buttons won't work, absolutely nothing works. I tried jumping it and that didn't work. The truck doesn't make the clicking noise when i try to start it. I know nothing about cars.

Added (1). I just want a general idea of what could be wrong. I don't like going to mechanics without a vague idea of what could be wrong. I've had mechanics do a lot of stuff that didn't need to be done and it costed way to much

Sounds like the connection from the battery to the car is incomplete, have someone check the main wiring foryou

Get a mechanic to figure it out.
Can b as simple as New battery needed

Dead battery and a dead alternator and a bad starter

Bad battery or blown fusible link.

A battery that's COMPLETELY dead or has internal dead cells will prevent starting the car by jumping.
