Your wiring looks OK. It is possible that pins D2 and D3 are damaged on the Arduino. This can happen if they are overloaded.

After verifying the D2 · D3 in the sketch that lights the LED, it did not move .

D2 · D3PIN seems to have failed .

If you do not use the serial monitor , it is safe to remove this?
Serial.begin (9600);
Serial.println ("Card failed, or not present");
Serial.println ("card initialized.");

Do you who the removed becomes faster processing speed ?

Thank you very much

It is safe to remove. But you will not have any error output if the SD card fails.

No. Since there is no serial output in the loop. There will be no change in the loop speed.

If you want to increase speed, you can try using direct port i/o:
