Hey all,

So my bike had been sitting for around a month when I went to start it. I left it with a full tank of 93 octane gas, and I had been driving it fine all winter. It cranked over, fired up for a second, then cut off. I smelled some fuel, and I've heard the fuel pump go as well. After that, all it would do was crank and not get a spark. The battery was fine, since it was cranking strong, just not firing up. I also tried the WOT 10 second thing, which yielded no results.
After trying to start it a few times, I waited until the next day to try it again, and the battery started to die out from me doing it so many times, so I put it on a trickle charge and charged it back up. Also, the engine start switch is on, just to eliminate that.

I've since checked the fuses, drained the gas, and removed the spark plugs to take a look at them. I've also changed the oil in it, since I had it taken apart anyway. The plugs appear to be fine, but I'm waiting on new spark plugs to arrive. I can't help but think that those probably aren't the problem..although has anyone else had this experience of the plugs looking fine but actually being the problem?

The bike is an 05 RR with 3,000 miles. I would imagine everything should be in fairly decent working condition, since it's such a "new" bike. I don't believe the bike is throwing any codes. The bike is bone stock, except it's been lowered an inch from the previous owner.

What should I start checking next? is there a way to check and see if it's getting a spark using a screwdriver? Or is there anything good to try and clean out the injectors? I'm pretty stumped right now, and any help could be appreciated.

I had the same thing happen to me as well. I had sta-bil in the tank and everything.

have you tried holding the throttle 1/4 -1/2 open when firing? after a few minutes of hold this open while starting it finally fired.

The fuel shouldn't be the problem whatsoever. I don't know why people worry about the fuel so much. It is still fine after a month or 2. Try cranking it with W.O.T

Tried both of those, it still wouldn't catch. I tried WOT and different variations of opening the throttle. Still not sure... I figured the gas would be fine too, it was really only sitting a month and a few days. It's not like it was the entire winter. Still waiting on the plugs...but doubt if that'll help much.

i'll keep trying and let you guys know.

So i just changed out the spark plugs...still nothing. I'm not really sure what to check next that would be easy. Is there a way I can check to see if it's getting fuel? I guess try starting it and take the plugs out, and see if it has gas on it? Or any way to check spark? I'm really stumped on this bike...it was running fine a month ago with no problems at all, and now it's just not starting, despite me changing practically everything simple.

Any advice?

so,

I took apart the gas tank and tried starting it up, and I can see that the injectors aren't pumping any fuel out. I would imagine that all four injectors getting plugged up at once wouldn't be very likely, and there isn't even a drip of fuel coming from them. So, I suppose it could be my fuel pump. The problem is I can hear the fuel pump running. Could this be some sensor or computer issue?

I would imagine that when the battery died, and I took it off and charged it the whole day that would've pretty much reset the ecu. So I guess maybe that's not the case. That's a good check though, and I'll do it again just to make sure.

another question:

if it's the back angle sensor, will that cause the injectors not to inject fuel? or will the bike not even try to turn over?

i've determined that they are just not working...and everything else is getting fuel up until the injectors.

after dumping more injector cleaner into the gas tank, the bike is now starting. it's still running a little poorly, so I'm thinking that it could've been a fuel filter that was gummed up or something like that. anyone else have any experience it?
