What are the numbers?

I wouldn't trust ohm readings on sensors other than those for
temperature, and I certainly wouldn't trust Chiltons. I doubt a crank
sensor would make it go full rich.

Have you tried connecting a 12V bulb to an injector plug and see if it
glows with the key on but the engine not cranking?

And you're sure it has a spark? Fuel flow with no spark will cause wet
plugs as well.
