I think you may have connect the battery jumper cables in reverse....

Check your battery voltage, if's it's low, replace the battery after it's load tested at your local auto parts store. Battery can blown up if the cables are hooked up backwards.

If the car doesn't respond, check your main fuses - you may have blown some ecm's possibly from hooking up the jumper cables backwards.
