Have a no start issue on my 96 V-6. Tested for continuity between the two terminals. Sensor is still in engine.
Have no continuity.
Is this good enough verification to condemm the sensor?

Firstly, any CELs?
Secondly, is the Check Engine Light on for a few seconds, when your key is turned to on? (to determine if power is getting to the PCM).
Thirdly, was it cranking and not starting? Or was it nothing at all? (to determine if the starter is bad).
Edit. Check wires from battery to alternator and to ground. Then test the CKP using an automotive digital volt/ohm meter (DVOM). Place the positive DVOM probe to the signal (CKP+) wire pin in the CKP's harness connector and the negative DVOM probe to the engine block. Select the Hz function for DVOM (as our CKP is a Hall effect sensor)and crank the engine. If you don't have a reading, then only would I condemn the CKP.

No CEL
Check engine light is on with key in the run position. Goes out when you crank it.
Cranks but doesn't start.
Been doing some reading up on crank sensors. Doesn't seem continuity testing is the correct way.

www.teamfordparts.com CKP $19 can't go wrong....(unless it wasn't the issue to begin with). Good luck.

Thanks I'll try your hertz method test first. If it is bad I'll just pick one up at the dealer nearby.

Tony2005, are you sure the CKP is a Hall effect sensor? I've looked at both Mitchell On-Demand and Alldata wiring diagrams, and both show the CKP and CMP as inductive pick-up coils for the 96 V6.
Pick-up coils are two-wire sensors that produce their own AC voltage, while Hall effect sensors are three-wire sensors that need power and ground to produce a switched DC voltage signal on the third wire.
If there isn't continuity across the two prongs of the CKP, it can't produce an AC signal or any signal for that matter. This should be the first test of any questionable pick-up coil sensor.

I could be wrong. It has happened before and will probably happen again. 
But I based it on this article I read.

Edit. I stand corrected. Thanks. The CKP and CMP are inductive pulse sensors.

Tony and stuvx, thanks for the info.
I tested my cam sensor for continuity also. It too is open. I had taken the area of fuel charging harness connectors out of the car for a closer inspection. The sheilding for the crank sensor was completely in pieces, the wires going into the connector at the CKP have the insulation cracking in many spots. It still had continuity from where the line ends at connector 179. I ordered a new harness for approx. $600 (hopeing to get remembursment from Ford)
I am thinking when I tried to restart the car with the old harness the wires shorted out and killed the CKP? But the Cam sensor wires looked ok, so I really don't see why it too shows no continuity? Hense my question, am I tested them correctly?

I wonder if you might have a problem with this later. It is not a safety recall, and they might not honor it if you do not bring it in for them to make a determination if it is a wiring harness issue.

I have started the process. I was replacing all the coolant hoses, cleaning intake manifolds and inspecting the injector harness. I told them it was stupid to put back the harness after seeing how bad the CKP sensor wires were. The car was fine before I disconnected the CKP. I want the car running before I take it in. The harness to the PCM also has a few wires cracking. They can do that one.
