Hey, I thought this might help. I was having the same EXACT problems as you are with my lebaron, and after much trouble shooting found it to be corrosion and water built up between the battery terminal and the terminal post, because somehow the post donuts had become wet.
The minute I cleaned out the the terminal and brushed the posts I had no problems. Also if you have the good ole oem toyota slider on the back, those are prone to loosen from the chassis and you may have a live wire in some water. Something to check into...

If you have not fixed it........
Check all ground wire grommets, especially the starter and solenoid. What happens is that the current gets to strong and shorts out because it is not tight.
Good luck.
