Start by checking for DTC / Trouble Codes
The Check Engine Lamp Diagnostics will not indicate the existence of historic trouble codes- only current
trouble codes are transmitted.
Use of check engine lamp diagnostics assumes that the SCANALYZER (Part No. HD-41325) is not available.
1. To activate the diagnostic feature of the Check Engine Lamp, proceed as follows:
a. Turn the Ignition/Light Key Switch to IGNITION for three seconds (one second pause after the fuel pump
stops running), and then turn switch back to the OFF (FLHTC/U-I, FLTR-I) or LOCK (FLHR/C-I)
position for three seconds.
b. Repeat the instructions under step 1a. above.
c. Turn the Ignition/Light Key Switch to IGNITION and wait approximately eight seconds for the Check
Engine Lamp to start flashing.
2. All trouble codes are sent out as a series of flashes.

The crank position sensor reads the notches on the flywheel and is "looking" for speed of the flywheel and the empty spots for ignition, if the CPS doesn't "see" the information it won't send a signal to the ECM or spark to go to the ignition. If the CPS is bad, then nothing will happen. I don't have the procedure to test (ohm out) the sensor, but this would be my first look see.
