I have a 2003 Ninja 636 that has been sitting for 3 years. I just changed the battery and added new gas to the old gas that has been in the tank for the last 3 years. It still wont start. Any trouble shooting ideas?

Sheeesh 3yr old gas is'nt gas any more, drain the tank and fill with 93 octane add injector cleaner. change spark plugs. Be prepared to charge battery. Good luck!

If it's been sitting for 3 years I would do as follows 1. Drain tank of all gas, give it some fresh gas. 2. Change the Spark Plugs Attempt to start it. (Keep in mind it may take a few times to get all that old gas out of the lines) Sitting it the worst thing for a rig. I advise never let it go without starting it ATLEAST once a month If that doesn't work make sure it is getting fuel to the motor. If so it could be your Distributor or Coil. Good luck
On your post "...does not fire..." initial checks would be for:
consistent IGN + 12 on the red wire going to all the ignition coils even when cranking;
pulsating voltage on the other wire of each ignition coil coming from the ECU when cranking.
Incidentally, if the bike has been sitting for 2 months, you may want to check quality of fuel and/or replace it. Further checks maybe required on the fuel delivery system. Try of a quick fix would be adding / spraying injector cleaner.
Good chance that the fuel line/injectors/etc. have a varnish on them from the gas evaporating over time. Needs a good cleaning. Suggest something better than just pouring something in gas tank.
either siphon from the filler, or disconnect the fuel line from the carb and put into container, then turn over the engine to pump out the fuel. You also could try turning the bike upside down lol
Gday. . Remove both your seats, this allows you to be able to undo the 2 bolts to the tank that sit under your seat, theres 2 bolts at the front of tank that need to be removed. As your lifting tank off youll need to remove the fuel line as well. make sure to turn fuel tap off before removing. Once tank is off youll see what needs to be done from there. Pretty straight forward
Unfortunately if all you did was dilute the stale fuel you will have to remove the entire fuel system and clean/replace.Stale (old)fuel becomes acidic and works like an acid.If you remove the fuel system yourself avoid getting it on your skin as it burns(personal experience)At least its not an ignition fault as the engine wants to run with an independant supply of fuel(start fluid)Sorry cant supply cheap alternative but there you are Good luck and let me know how you go with it.
