check your battery voltage.

your starter motor solenoid may be faulty or the relay could be faulty.

If you get a multimeter on the large positive terminal and one lead on the bare metal on the body and get someone to turn the key in drive or neutral if it is an auto (handbrake on).
you may have to get under the car to do this.

If you get no voltage the relay maybe faulty, if you get voltage the solenoid is faulty.
