Iʻll post this here and in GA.

1999 Ford Taurus 3.0 OHV auto.

Car was running until overheated, engine shut down.

Made some repairs to coolant plumbing, but now the overflow tank is

cracked (or was cracked and caused OH).

The problem is the car will not turn over. Everything is turning, but

I feel that there might be timing chain issues.

Could it be possible that the timing chain jumped?

There are not any trouble codes now, I cleared the coolant sensor DTC

with a new sensor.

There is fuel at the rail.

I guess I will check spark.
