Hi there,

I hope anyone cold help me out with my problem.
I planning to buy an Escape Hybrid from '06, but the previous owner put in a new 12 battery in the wrong position so, he exchanged the polarities (+ went to the - and the - to the +).

Since he did that the car wont start.

What could be the possible problem? What should I try out? Is it worth the effort, or I should just let it go?

Thank you for your kind help in advance!

 

Could be anything from blown fuses to fried ECUs.

 

The blown fuses would be the best option... but the fried ECU doesn't sounds good at all.

 

I think you need to add more detail.
What does it do now? Lights work? Engine cranks? Be specific.
