2007 Fatboy. Just finished the top end. It cranks but does not produce spark in the motor. No trouble codes or check engine light. Changed spark plugs and wires and same issue. Batteries and fuses show no issue. Been told either ignition coil or crank position sensor. I did bottom work and top end rebuild. All wires and gaskets are in place the only thing is not sure if there is a way to determine either its a sensor or coil. Fuel pump is working btw and fuses were all checked as that was checked as well as the quick disconnects. Not compression either since i got brand new compression releases. Looked through the service manual and went through the fuses and ignition switch all properly seated and has power to them. Fuel Injector's connecters are good. Only culprit is the ignition coil but wanted to know if anybody has ran through this problem before.

 

Does the motor have any compression? Needs compression on the rear cylinder to make spark. While the fuel pump primes on "key on" can you hear it run after cranking??

 

Motor has compression. Ignition components and crank sensor all changed out. Fuel Pump runs. No fuel is getting to the spark plugs however. Maybe a clogged line or injector.

 

You got spark?
