If you have nothing plugged in the thermistors connector, the firmware "reads" a very unusual temperature and throws an error and stops working. Put the thermistors there and it will read room temperature, or put a resistor like 100k to 10k in its place so it will "read" some temperature at which it will work.

Lots of questions to help diagnose your issue..
Do you have 12v wired into the 12v 5amp ramps power socket? this is used to power the steppers. is this power supply on?

Is the Stepper driver plugged in the correct way? Please provide clear photo of the board as it is currently wired. See if we can see anything

Is the stepper wired correctly, if you have followed any color based diagrams its probably wrong. Identify the coils and make sure coil one is on pins 1 and 2 and coil two is on pins 3 and 4 of the stepper plug. More info here

Dust
Have you set the correct board type in your firmware (normally 33 for a ramps)
Quote
Dust
Have you adjusted vref (slightly different depending on your driver) eg [reprap.org] eg [reprap.org]

Dust
Are there 3 microstepping jumpers plugged in under your stepper drivers?
Quote
Dust
Do you have endstops configured or disabled? (If they are enabled, you cant move in the direction that is triggered) check with a m119 command to the board

Dust
And finally what type of stepper is it? as some just need to much current or voltage and aren’t suitable to be driven from a pololu type stepper driver.

bit late for a full reply, so this is quick...
check those endstops. Normal setup is if the switch is open or disconnected, it is treated as triggered and will stop movement in that direction.
re the vref, it only spins 360 degrees, so spinning it a number of revolutions doesnt help anything.. (most have stops so they only move about 270 degrees)
put it back to mid position for now (there should be a flat edge, make sure thats pointing away from the legs)
Put all 3 jumpers on the microstepping jumpers
