Agreed. The crankshaft position sensor is the primary suspect. And with a motor swap, the wiring is often damaged. Check it.

I actually meant transmission swap, as the crank sensor is located on the transmission bellhousing.

Only takes a few minutes to follow the wiring from the crank sensor to the connector inside the engine bay.

Check it for damage and be sure it's connected to the connector located near the firewall #6 injector.
