Crank no start

Hi - I am Dave, contributing to RepairPal and providing expert advice since 2010. If the jumper cables were crossed and hooked up to the wrong posts, you could've done some major damage or blown some fuses for sure. I would start at the fuse box and see if any fuses are blown. The fuse box under the hood. You could have also caused other electrical system issues. I would recommend seeing a shop near you for guidance. https://repairpal.com/auto-repair-near-me Click the link to find some shops near you who can help out!
