    your bike is all stock right devil. maybe pull the injectors then adn clean or replace them, i can see old gas gumming them up. i wouldnt play the bypass game too mucn man, im no export adn im sure more peeps on here know tons more then me but the more you change stuff liek that the more i would think your computer will get more confused.

    if you have power to the injector but no pulse when cranking then its not getting the ground signal from the ecm.this could be a bad ecm,crank sensor,bad ground or power to the ecm.i could walk you through the diag over the phone but not until friday.you should check for a 5 volt refrence at the tps and see if you have spark.if you have spark if it has spark that would rule out the crank/cam sensor.im pretty sure your pcm has 3 grounds to the ecm each one needs to be checked using wiring diagram it also has at least 2 12 volt feeds to the pcm.if your power and grounds to the ecm are good no problems with the crank sensor its a safe bet its the ecm.if you want my help over the phone pm me

    Don't believe you've said, what's your bikes year model? If '07-earlier than ECMSpy has an Injector Diagnostic you can run.
