The crank position sensor tells the ECM where the crank is so the ECM can fire the plugs at the right time, if it fails the ECM thinks the crank is not rotating so no spark, it is located at the front of the motor beside the oil filter.
I agree with cHarley about the trouble codes, check them first, if there is more than one stored clear them and check them again after it does it again.

You can't. Short of maybe HD plugging in their diagnostic computer you are SOL when it comes to getting the DTC's if you don't have a speedo.

These sensors have a history of failing and it seems to be related to heat. I have installed a C clip on the mounting screw under the sensor to give the sensor about a .010" standoff and it seems to have improved the situation. I'm thinking these sensors really need some form of a heat sink, as these issues keep cropping up in the summer months. I'm seeing this problem mentioned on other HD forums as well.

I have never seen the pickup housing crack, but they do seem to fail (throw dtc codes) when the motor gets really warm in the summer months. I've got 3 sensors on the work bench that look and test fine, but they all throw DTC codes P0373 once the motor gets up to 200+* (oil temp) and you push for over 90 MPH in 4th or 5th gear.

ok....i will clean off all the caked on oil and road sludge and take a look.
i guess i could start there.... from what i'm reading its most likely the sensor or the coil, and i really think the coil is fine.
i'll try to see if mama will give me the thumbs up on a new part.....
o i almost forgot....thanks for all the help guys
