None of my stepper motors are moving.

Ok, just as some other people on here are having problems my none of my stepper motors will move. I have gone over the wiring and everything is in order. I'm assuming I need to load firmware and am not sure where to begin as I am new to all of this. Any help would be appreciated. Thanks.

I have the i3 pro B model with sanguinololu board and A4988 drivers.

The heatbed and extruder both heat just fine, the only thing that isn't working are the motors, they make no sound or anything.

There is one reason may cause motors not moving, the jumper caps are not plugged under A4988.
