I've had to replace the battery teminal connector on all of my Ford vehicles. Look for a swelling of the cable insulator...that means there is corrosion. One way to make sure is by removing the cables from the battery, pouring some baking soda/water mixture (this neutralizes the acid) on the terminals and posts and repeat this until it quits foaming (completely neutralized), drying it off (air dry), reconnect the battery and then try jump starting it. It should work. If the corrosion is too bad, you have to spend the couple of bucks to get new connectors. That's what I would try first.

yeah the terminals/ battery were replaced in the winter. but i did find oxidization on the negative cables in the middle so im thinking they just might of bit the dust and corroded out
