My car was jumped with the cables in reverse, so the polarity was reversed. I have take cables off battery, check fusible link fuse, efi fuse, bat notvall. The car had no problem starting but gas peddle has no power.

Yep they don't like it when the cables are reversed. Do you have security light blinking while you try to start it? I would try a hard reboot of the system this video will show you how.

Please go over this guide which explains more on the issue,

Did you check the fusible links with a test light to make sure they are getting power through them?

So to be clear when you press the gas pedal the engine does not have any power, or the is no 5 volt reference to the accelerator sensor in the pedal? I think we should run the codes to see if any come up. Please watch this video

I would double check the fuse as well. Here are the main fuses that power the systems, please go over these again. Check out the images (below). Please let us know what happens. Ken
