First things first, Hello to all! Alright my poor bike wont start...I kind of have neglected to care for it since I moved from my parents house. So basically it has sat since last summer and being started or anything( No stabil) in tank either, Long story short now it wont start. I replaced the spark plugs even though I was getting spark. I pulled the fuel tank and drained all the bad fuel and replaced with new even added some fuel system cleaner. Also I replaced the battery...still wont turn over. When I turn the key my lights come on fine, my fuel pump starts fine but when I try to start it, it trys to start but needs that last little push in order to fire. Im out of ideas!! I am getting a CHECK ENGINE LIGHT then F1 flashes. Im sure that has something to do with it. Any Info would be appriciated!

had this same prob about 2yrs ago with my triumph and it was the injectors. So I did the same things that you did and finely jst pushed it and after a few times it started and never had any more probs with it.
The injectors my be lacquered up and stuck.... it my take awhile to get them to brake free. have you tried to push start it? I would try that a few times and seet if you can get it to start that way.

No not the throttle bodies as all thay do is open and let air in so all they ever see is air. The injectors are what pressurizes, atomizes and delivers the fuel in to the cylinder and are controlled electronically be the ecu.

you may need to pull them and clean them but now your talking a relatively in depth job and remember that the fuel supply system is under high pressure so you'll have to bled off the pressure be for you unhook the lines from the injectors.

Also what year size is your bike??

you are getting spark and air so it seems you are not getting any fuel probably cause it just sat up for so long.

you can try starting it and hopefully pushing all the bad gas out of the lines and injectors or you might want to think about having someone actually clean the injectors out.

Injectors have electrical connection going to them which tell the injector when to let fuel go. The electric pulse can try all day but if the path of the fuel is blocked by gummed up stuff in the actual fuel flow path of the injector aparatus well you get what you get. Could even be there was water at the bottom of your tank to begine with and its gotten you injectors fouled up. Drain the lines and try cleaning the injectors. Not sure if you have two for each cylinder that would be a main injector then a secondary injector for when going heavy on the throttle. Might be a pain to do and possibly break an injector getting it out. But that FI light that trys to be a big clue to your problem should be solved. Hopefully the fuel pump isn't jammed up too. I think there might be some sort of flush solution you can use to clean out the ines with out taking the bike apart. Try searching the internet. Heard of something like sea foam or another name mentioned before.
