Was receiving jump and the guy hooked jumper cables backwards now i have no spark and no fuel any ideas?

If the jumper cables were connected backwards, it could have caused damage to the vehicle's electrical system, including the battery, fuses, or electronic components. Check the fuses first, as a blown fuse could prevent the spark and fuel systems from functioning. Additionally, inspect the battery and wiring for any visible damage. If these steps don’t resolve the issue, consider consulting a professional mechanic for further diagnosis.
