Odd starting issue

[BLaCk_1cE]

Just got back from up north for about 5 days and tried this technique. I hooked the positive jumper up to the positive cable and the negative jumper up to the chassis, and nothing worked in the car. Then, I tried attaching the negative jumper to the negative cable and the problem came back. While I let the negative jumper sit attached to the chassis for a while, the power actually came on, everything worked-lights,radio, windows, etc. The only thing that didnt happen was that it didnt crank this time. So, does this mean that I need a new negative cable then? or what does that mean exactly?
