I am not sure. Am trying to find the answer for you. But I know someone else will beat me to it.

Won't crank, or won't fire? Seems really odd if it won't crank...

If it cranks, but won't fire, I'd be looking at the distributor to make sure you didn't unhook something important there when you were hooking up the tach.

Black wire to battery? Black wire is typically ground, if you wired to negative post on battery that's good. Could also connect to any good ground under the dash. Green to distributor, tach terminal on HEI or negative on coil of points system. Red wire to anything hot when car is in run, their is a IGN connection in fuse block that is a good point.

You didn't mention what type car, year, type of ignition and type of tach so I'm making some assumptions that may not be correct.

Man, just go back through and retrace your steps. I'll bet you find what is wrong yourself. Check your connections, and make sure nothing got loosened when you were trying to put the tach in.

I'd just unhook what you hooked up and see if that corrects it and if it does you can kick yourself then....ask me how I know...ha.

Word of advice...never make to many changes at once as if anything goes wrong you can just undo it or concentrate on what you did to correct it.
