hi,
i currently a 2000 cbr929 all stock except for exhaust slip, purchased it for track use only. however got so excited and did not checked the bike properly for leaks. all i care that time was to buy it and use it on track. so when after using it on the track notice that there is a leak on the stator case cover bottom parts on top of the rad hose. tried to fix it previous owner weld it and still leaking did everything i could. but end up acquiring a engine and frame no harness and no front end. thinking that i will just move everything i have in the other one and there problem solved.

so that what we did move everything from front end to harness, ecu , throttle body etc. tried to start is it was just cranking. check the plugs and they were dry. so we open the air box to see if there is any gas squirting on the injector. but when starting open throttle no gas squirting on the injectors, checked the fuel pump everything is ok open the nut that goes to the fuel rail and there is gas coming out when ignition on.

story short any idea why is the injector is not squirting gas? where problem to look at the throttle is from and harness moved to a working bike.

are we missing something?

thanks and hopefully someone experience this issue and can share what was the solution.

 

Opening the throttle does nothing for fuel spray. Did you use the fuel rail from the engine that ran? What else did you swap over?
Check your grounds for the fi and relays. The injector should have ignition power at all times and a ground pulse through the ecu during cranking.
