strange start engine issue
I am new here and this is my first post here on the form and i admire any help. I had a good search but could not find the similar issue posted.
My 2008 Cbr600rr have some starting problem, everything is perfect and works fine but for past 2-3 weeks it has developed a habbit of not starting on the first try. everything goes fine starter moves but the bike just wont start, try again no, try again ooh yeah even with slight touch of the button engine fires up. Points to consider.
1) it happens when bike is cold or hot, however i noticed more in Hot state as in 24 hours bike is only cold when i start in the morning and then i ride it with interval off 3 hours during the day.
2) the bike got a new battery in april after it was brought out of winter storage. while changing battery i missed to connect a wire and then the bike was not starting everything was fine just the engine was not igniting, i guess that cable has something to do with alarm/theft system and cuts off the spark to the engine. but later i realize the mistake connected it and the bike worked all the way fine, i dont know what that cable is called and what does it do i just assume it has something to do with the ignition.
3) bike was going fine all the way but once or twice a week it did not start the way it used to be with a slight touch to the start button. i did not care at that time however now the frequency is higher it starts in half touch 50% of the times i start it but rest of the times 2-3 tries and sometimes a long press.
4) there was some motorcycle alarm was also connected, by the previous owner, which i disconnected assuming it could drain the battery and i park the bike in personal garage.
what could be the problem. what shall i start looking into. allot of thanks and appreciation for the help.
************** Hi guys, the fuel pump does not prime sometimes my mistake i did the wrong troubleshooting in the start. it seems like its intermittent with the fuel pump wheneveri t primes it always starts when it does not it does not. now i need to sort out why does not it prime sometimes leading to no start.
