Why PIN never goes LOW?

Hello,
I have this simple code:
Code: Select allvoid action() {
digitalWrite(2, HIGH);
delay(2000);
digitalWrite(2, LOW);
}
void setup() {
pinMode(2, OUTPUT);
action();
}
void loop() {
} Why PIN never goes LOW? I am measuring continuity between D4 and GND.
Thank you.

If I put that function into loop(), PIN is 'blinking' HIGH-LOW over and over again, but i need it to do only one during setup. What did I wrong?
Thanks again.

because its in your loop, instead put it in setup

I did. See my first post. Problem is, pin stays HIGH and doesn't go LOW after 2 seconds, as it should. I have no idea why.
