My batteryhas full juice but the car won't start wont even click when I try to start it. We tryed to jump it and still won't start. Can somebody help me please. Thanks

 

Check the fuse box under the hood. There are several "large" fuses (technically called fusible links) in this box, one is a 30A for the ignition system. If it's blown, you will need to replace it but first give some thought as to what made this link blow. Fusible links are more costly than your average automotive fuse. Fuse #1 in the box under the dash also provides power to the ignition system. Also, if the link is blown, you should check all of the fuses in the box, both under the hood and the box under the dash.

If the fuses are OK, then I would check the starter relay found in the fuse box under the hood. The starter solonoid on the starter motor would be the next item to suspect.
