Wire end to end should be 0 to 5 ohm max.

 

Wire to ground should be infinite.

 

Test for 5V with the key on at the sensor plug.

 

Then I would replace the sensor.

 

If still not right then I would send the ECM for testing.

I appreciate you simplifying that for me. I did those 3 things and got those results. Buddy I bought it from says he got it tested, but maybe he was told wrong. Where should I send it to get tested?

The easiest thing to do is drop your starter and pull the CPS then with a mirror or borescope check the tone ring. I fought the same problem for a few months. It can be fixed without pulling the motor, as long as you have some patience. I'm working on a write up to detail the whole thing. Dodge no longer sells the parts but cummins has them for about $150 you will get the tone ring and 5 screws that hold it in. I have part numbers, torque specs and a tool list. Pics of the position the crank need to be for install.
