Needing garage door help!

Possibly. I've had good luck using the extension style springs, my understanding is that they're less fussy. If you have the room for it, you might want to consider switching the door over to that style. There's a way to calculate/measure the needed spring values, but I don't have it at hand at the moment.

What do I need for that? Yes, I have the room. That is just where a spring and a puley are used right?

Two pulleys, actually. One at the top of the upright section of track so that the cable takes a right turn from vertical to horizontal, and another that the end of the spring hooks onto. The last end of the lift cable then attaches back near the first cable (in essence, the spring has to work twice as hard, but move half as far).

Tension is adjusted so that the spring has no tension when the door is all the way up, but not so loose that the cable falls off the pulleys. Select spring ratings so that they just ballance the weight of the door. This stuff is out on the net, too, for a more detailed explanation and a few helpful cautions and such.

There is a second cable for safety that runs through the middle of the spring, straight, which does not affect its operation, but is intended to catch all the bits and pieces if the spring work hardens and breaks.

If you go to any of the big box home stores they should have all the necessary bits and pieces in their replacement parts section... --Glenn Lyford

Might be the old wire is just kinky now it is off. Once stretched, it doesn't go back.

With luck, a pro installer will be on line.

Start by setting the pulleys so that both cables are equally tight with the door lowered. You might have to clock the pulleys on the shaft so that the clamp bolts aren't trying to settle into previous "dents" on the shaft. Tighten the bolts on one pulley and rotate the shaft until the cable is tight. Then clamp a visegrip on the shaft, oriented so that it's jammed against the wall to prevent the shaft from turning and unwinding the cable. Now tighten the bolts on the other pulley so its cable is tight. Then wind up the spring and tighten the clamp bolts. It tends to take about 7 turns of the clamp anchor IIRC, but you'll have to experiment until you get it right. Don't forget to lock the shaft with the visegrips each time you readjust. And be extra careful, lots of people get hurt installing garage doors. Make sure that the turning bars are a good fit and are fully inserted before you crank on them. I keep a spare bar and a spare wrench in my pocket in case I drop either.

Sounds like the cables aren't equally tight. Make sure that the door isn't binding anywhere. The tracks should be oriented so that as the door rises it comes away from the wall.

Once properly adjusted, the spring should hold the door in any position, and the cables always stay tensioned. Take care that the door operates cleanly and isn't so crooked or whatever that it's trying to come off the tracks. You'll have a real mess on your hands if one cable comes off when the door is partway up. And an even bigger headache if it falls on your car or worse.

I think you'll find that once you've figured out the correct sequence, it should only take about ten minutes.
