Please help with circuit build

I am making a board to power a 12V vacuum pump, with the use of a MOSFET to turn the pump on and off, (with the code below) and I am using a motor to see if my design/circuit will work but I really cant tell if is working and I would really appreciate some help!

const int RELAY_PIN = 3; // the Arduino pin, which connects to the gate pin of MOSFET

void setup() {
// initialize digital pin A5 as an output.

void loop() {
digitalWrite(RELAY_PIN, HIGH); // turn on pump 5 seconds
digitalWrite(RELAY_PIN, LOW); // turn off pump 5 seconds

If you wire up that circuit and run the code the motor should start and stop for 5 seconds. If 5 seconds is too fast to see if the motor turns off change the time to 20 or 30 seconds to make the shutoff more obvious (or put an LED with current limiting resistor across the motor as the LED should go off for 5 seconds without the lag the motor may have.)
