What happens? Do you do the 'diving' animation or do you just fall as if you didn't have a parachute? Is the parachute on your back? Are your keys defined correctly (KEY_FIRE in GTA: SA settings)? Do you give the parachute before SetPlayerPos or after? Do you set the interior? Do you even use SetPlayerPos? You could just use SetPlayerInterior(playerid, 0); to let them fall from where the andromada interior is (above the quarry/fort carson).
