Seems to me around 01-02 and up the tach won't move while cranking. I can't remember why off the top of my head.

This is what I have found on the net. Not sure of the validity of it, but mine doesn't move either.

2002 or newer truck, the "No TACH Movement During Cranking" troubleshooting trick
probably wont work for you. Ford changed how the TACH gets its signal to a computer controller
and so it does not move AT ALL until the truck is fully running. However, if the truck was
running and the TACH falls to zero, start looking into the CPS.
