There is a start relay in the undrhood electrical center tapon that and if it starts replace it. It may be your starter as well. Or a battery not giving enough power. If you can jump it and the car starts then charge the battery and have the battery checked for power.

This is a wiring diagram for the system
it shows that you have a fuse and a relay in the fuse box under the hood very much dough it is but should be checked
2nd pic shows the starter big wire should have battery positive at all time, small S terminal should have battery power only when ignition is in start position
