I have 1997 thunderbird LX with a 4.6. Now I have no spark. Checked all fuses all fuses are good. Now what? Tim M. Chicago Took battery out, hooked it up backwards by mistake, now has no spark. What to do.

What has no spark? If you took it out then hooked it up backwards you wouldn't have hurt things under the hood. The battery may be damaged, but really shouldn't be.

Check main fuses under the hood, check fuseable links.

Check for power to the crank sensor and coils.
