A bad power supply, broken power cord, failed on/off switch or bad drive motor can prevent the band saw from starting. If the power cord is okay, use a multimeter to check for continuity through the on/off switch with the switch turned on. If the on/off switch is okay, check the wire harness connections between the switch and the drive motor.
On a typical wood or metal cutting blade the hook or of point of the blade should be pointing down for a vertical blade bandsaw, or for a horizontal blade saw the hook of the teeth should be pointed such that they enter the workpiece first as the blade moves. During regular cutting on a well set up bandsaw the blade will move or bow backwards a bit as you press the workpiece into it. The side guides will assist in keeping the blade cutting straight, but they are not an iron lock on the blade forcing it to cut straight.
