Checking Crank sensor with Tac?

[Luckyman01]

I head somewhere that if your car cranks and does not fire, you can observe tac to take the crankshaft sensor off the table True? How many RPM would you expect.

I have not checked fuel, however I have reviewed Bentley and understand how. I don't know how to verify spark.

I did try to pull codes on an Autel and found nothing.

Any aid appreciated.
