It is many cases where the CKP sensor sends a good enough signal to trigger fuel pump operation but not enough to trigger spark.
So checking for fuel pump operation or not is not a good enough rule for the CKP sensor being bad or not.
When you unplug the harness from CKP sensor, then the fuel pump does not come on with cranking, only the 2-3 sec prime.
