Changed handlebars, now wont start
2009 flhtcu, I swapped my handlebars for TBars. Theres about 30 or so wires coming from the control housings so I did not internally wire the Tbars except for the throttle wires. Everything works just fine except for now the bike cranks but wont fire up. You can hear the fuel prime when you flip to run. Hit start and it just cranks. I ride this bike almost everyday, it was running great with no issues before I changed the bars. No pinched wires at the control housings. All the plugs are plugged in. I am stumped, I've gone over these wires and plugs for too long now. I need help, what am I missing?

At the expense of stating the obvious you have not connected all the wires in the right place or you have a broken wire or a short.

Has your predicament caused and trouble codes?
Having removed wires from plugs have you mirror imaged them, reversing their orientation?
Have the pins been fully inserted in the housings, none backed out? Has a pin(s) got bent?

Probably a wire.
If the wires in the throttle are screwed up, bike may not start. IIRC if the ECM thinks the throttle is wide open, it won't start the bike and not throw a code.
