Engine not start

[baphomet666]

Hello all
need help
My truck not start.
the battery is new is full.
I checked all fuses, battery cables are clean.
When I want starter. the engine does not turn.
just a sound I hear "clack clack .. clack .."
Do you think a problem with the démareur.
or else the starter relay
THANK YOU VERY MUCH

EDIT
It's the starter
thank you very much

can you turn it by hand (clockwise) at the harmonic balancer? if so, then its a bad starter motor or battery or connections.
