Ok I havent had a problem up until about two weeks ago. But I started my bike up and it ran fine for about thirty seconds and then cut off. so I tried starting it and for some reason it wouldnt start so I completely cut it off and then back on again but it seemed like the fuel pump had a hard time staying pressurized. The FI and Heso lights (not sure what they are) come on and then turn off and sometimes starts fine, sometimes not. Im thinking it may be a relay. but im no electrician. any ideas?

 

btw its an 07 600rr

 

it's forced induction which means it doesn't have a choke right?

stupid question... you have gas in it right?

(sorry lol that's like the typical windows support question - "your computer is turned on right?") But that's the extent of my motorcycle knowledge right now.

edit - you have the owner's manual right? it might be in there under troubleshooting... mine is carb'd but there is a section for "Poor start, low idle, cutting off." or whatever.

 

The first thing i would do is check to make sure the battery terminals are tight. On some models, there is a feed wire to the fuel pump directly from the battery and a loose connection can cause issues.

Secondly, since you have a light, that means you more than likely also have codes stored. You can pull the codes from the ecu and it should tell exactly what is causing the code. It doesn't always mean a simple replacement of the sensor that is throwing the code, but it should get you in the right area.

If the code reading doesn't help, there are few things that you can check for proper operation. The BAS sensor is the first one I would check since it is responisble for shutting off the fuel pump. Then I would check the kickstand switch and killswitch.

Also, you may want to let us know how many miles are on the bike, if its ever been layed down, or if you have any accessories that have been recently added.

 

the bikes only got 8000 miles on it and its only been dropped from a stand still, cuz some a hole decided to sit on it at night and dropped it.
