Not cranking
2002 Ford Taurus SE 3.0 256000 miles.
I replaced the ignition switch actuator rod. After getting it back together the dash lights looked normal in each position. The only problem is that the engine won't crank. Lights look normal. Acts like when using a key without a chip. I've checked the wiring connectors as far back as I could and removed the lock cylinder and checked the sensor tab that makes contact with the cylinder. The engine cranked fine just prior to the actuator rod breaking.

RE: Not cranking
When all else fails go back to basics. Using a test light, does the crank wire at the steering column provide power when the key is in the crank position? If not then I'd look at the switch itself to see if it's NG or if that rod has a bit more adjustment to get full travel into the crank position at the switch.

Let us know how you make out/

Sad Sorry for the delay getting back. Been out of town. There is no voltage on the crank wire. This should be the RED/LT BLU according to the Starting Circuit wiring diagram. There is 12.14 V on the LT GRN//VIO lead coming in. While in start the power in drops to 11.54. The odd thing is when I remove the connector and place an ohm meter across the pins it shows open when in any position but start. When in start it drops to .2 ohms. The same as if I touch two probes together. So basically zero. It seems like the male and female are not making contact on either the power in side or the crank out side.

RE: Not cranking
It's old enough to suffer from bad connections. Perhaps a small tweak of the pins in that plug and some jiggling will help? It's also possible the switch is no good.

Edited to ask: What happens if you jump 12 volts to the start wire? Trying to figure out if it's an electrical issue or an anti-theft problem.
