I have a water pressure pump that pumps water to my house it won't pump any water to my house the gauge won't move at all, I don't know what to do

First steps:

1. Check the breaker. Is it thrown?
2. If the breaker is on, then check the switch (little grey box with electrical wires coming out). Pull the grey cover and check the contact points. Are they touching?
3. If 1 and 2 are OK, then use a voltmeter to see if you are getting current to the pump.
