old scoot coot
help harley gurus, im stuck on this. i took bike to car wash yesterday to wash off the bugs from colorado trip. it's the 17m8 ultra i just rode 1900 plus miles to the rockies and back. on the way home it started running rough then on one cyl only. i milked to end of my drive, another 4 miles or so. pulled in drive and wouldn't start. no codes. i figured i had got something wet maybe coil and connections. i took seat off and got the leaf blower and blew at coil and around that area. it then started and i pulled it down to shop and finished the clean up. restarted a few times to see that all was well, so i thought. anyway broke it out this morning and rode all around the area over to indy and back running errands. later this afternoon i had a dental in cherryvale so i fired it up and rode through town and it started running rough again, maybe one cylinder and died. i coasted into a parking lot and it would not restart. a little risky but i tried it anyway, i held the throttle wide open and the cyls flooded with fuel raw fuel running out the tail pipes and it tried to run. so i'm pretty sure i have spark but it will not start. still no codes. fuel pump cycles on when ign turned on. kill switch set to run. i don't even know where to start. i had to haul bike home. i think i have spark and fuel still no workie. where do i begin. can an ecm go belly up and not show any codes? it's an m8 with 42,000 miles.
