Forty Eight won't start after cable change

I have a 2016 Forty eight that I changed handlebars and all cables/wiring on this weekend. Now it wont start. It cranks great but will not fire up. Its not a pinched wire and i dont think its any fuses. Checked voltage at the plug wires and have 12VDC. It acts like its flooded. I'm pretty sure the issue is with the throttle cables, but everything looks ok. There is a strong smell of gas when I try to start it. Ive tried starting it with and without the air cleaner on. What should I check next? What should I be looking for. It's my first motorcycle so I'm not very familiar with them, but I'm not a mechanical dunce so I can follow instructions. ANY help will be appreciated

I should add that The fuel pump runs when I turn the ignition on
..and where can I find the fuse block?

Look for improper adjustment of throttle cables.

Just because they look ok.......

I know you are dealing with FI.
But I believe the throttle adjustment is the same.
Should be an 1/8" to 1/4" play in the throttle before the carb/FI starts responding.

In your case it sure sounds like they are too tight.

This might be old school because I am, but you need spark, and fuel. Smells like you got fuel so pull a spark plug and check for spark. If your plugs are wet you have plenty of fuel also.

Take plugs out of cylinders and let it air out and try again after checking cables . Fuses should be under LH side cover , or seat or Rh side cover

Try holding the throttle full open when turning it over after re adjusting the cable. If it is flooded it will allow full air and after some turning it should start firing a little here and there until it is cleared out.

Absolutely no throttle at start up on any EFI vehicle. If the cables are to tight it's like turning the throttle. Turning the throttle before the engine starts messes with the ECM calibration.
12 volts DC at the plug wires ??? What plug wires ?
Another thing. If the OP did all that wiring changing without disconnecting the battery pos. cable he should pull the Maxi-fuse for a few minutes to reset the system.

Yes, 12v at the plug wires. I cant find the fuse block to pull any fuses. Going to check the plugs when i get home then remove the throttle and idle cables. Id pull that fuse if i knew where it was.
