draw circle od as any value
select the circle,
then go to insert- curve -helix
give the parameters (like pitch, revolution...)
create one plane perpendicular to that helix at the starting point(use ref geomentry- per curve option- select starting point of helix and helix curve)
now create circle for spring cross section(its center should be coincitant with starting point of helix).
then select insert - boss- sweep - select circular cross section and helix path.

More questions to consider. I'll use coil springs as an example. Do you want ground flat ends? Do you want compressed end coils (that last coil is deformed so it is flat - perpendicular to the axis - a bitch to model).
Also consider are you modelling free length or compressed length (as installed)? A very interesting topic!
