Q: Troubleshooting a brief reversed polarity jumper cable event.
on 2003 Ford Crown Victoria

Reconnected jumper cables correctly and tried starting the CV. Engine would turn over but not start. Is there a "master fuse" that might have blown and could be replaced to fix this?

Did you check your fusebox? Connecting cables backwards can cause MAJOR damage even if fuses blow. You'll probably need to have a competent shop diagnose it. The PCM could easily be destroyed.
