Stalled on highway.

Replaced crank sensor.
Same symptoms. Crank but no start.
Same code comes back up.
Checked harness. No breakage or wear. Just oily at mid section.

I attached test light diags. At the connector for the crank sensor. With key turned at ignition point.

When you turn the key on without cranking the engine over can you hear the fuel pump run in the tank for five seconds? Does the ignition have spark? Will it run on starting fluid? Here is a guide to help us get started:

We should check the wiring between the crank sensor and the PCM. here is a guide to help you and the engine wiring diagrams so you can see how the sensor is wired:
