Harley no start

I'll have to check compression it didn't fire when I forced fuel in so that'd be a great place to start thanks!

Dunno for sure, I think it has to do with the flywheel cogs that pass thru the crank sensor and the software program in the ECM It is has not been a good way of testing for spark on late model ignition systems for some time now, even with modern car engines you may not see spark with a plug removed and grounded, how ever with the plug boot pilled back slightly you may see the spark jump, this secondary voltage should jump to the nearest ground path
