Ok, I'm new to "posting" on the site, but have had significant help in the past looking for issues related to my Buell. I have an 09 XB12R; I went out the other day to fire it up and go for a ride(sitting about a month and a half) and noticed the fuel pump wouldn't prime. I checked the battery voltage and recharged it because the exhaust valve was intermittent. After charging the battery and scuffing the ground cable the exhaust valve was working again. All of my relays are working properly(so i think) because I took the cover off of all of them and saw them click for myself. When I put the key in the run position I get three lights(N, Check engine, and low oil pressure). The check engine light goes off after 4seconds and does not return after 8. The engine will crank but will not fire. I do have spark( stuck a screwdriver in the plug wire and saw it arc to the frame). And the exhaust valve has returned back to normal operation. Now after troubleshooting some more the starter will not engage. The start relay is is also closing whenever i press start. I have voltage on pins 2 and 3 and the ground on pin one is testing fine. But now still no starter or fuel pump prime. Any help would be greatly appreciated. Thanks in advance to anyone who posts.
Fuel Pump will not prime; Different issues then previous posts; and now starter will not crank.

There are three codes(shorting pins 1 and 2 together data link connector); 21-Interactive muffler control; 33- fuel pump; and 44-Bank angle sensor. I think I actually threw code 44 on accident and I assume thats why the bike won't crank anymore?? How do I get past code 44 and back to testing code 21 and 33? thanks for your reply.
Hello and Welcome to the Forum! Might want to Pull out the fuse where power is for pump. Use a Test light to check for voltage, then test the fuse.If fuse is the problem make sure to put the Exact Fuse in that you remove so if there is a problem it will blow letting you know something is up.
Are you pulling the clutch in all the way at start up? Sometimes the Clutch switch up on the perch(lever)will short.I doubt it is that as new as your Bike is. It shows Neutral on your Guage Cluster so that is good. Also Letting the bike sit for that amount of time with no charge to the Battery system may be just the Battery is weak and not strong enough even with a charge sometimes.
The Battery is only 200CCamps or so. Some batteries don't last much longer than 3/years Depends on if a battery Tender is used on it about once a week to keep it topped off.When the bike is not ridden regularly. Have you checked the Start/Kill Switch? Sometimes the switch will not touch due to contacts for starting get worn or pitted etc.
I'm not sure the Exhaust valve is any problem at all, usually at startup only and fuel priming will be actually heard cycling. Remove the Battery and recharge it out of the bike. Might want to have the Battery Load tested at the auto parts store. Low Voltage can cause the starter to jam or just not enguage at all.
If the Battery is orignal from 2009 it needs to be load tested.Hope it is a simple fix.If you jump start the Engine make sure to not use a vehicle like a diesel OR jump it with another auto running just hook up and start, removing the cables Quickly off the bike.Small things first.When removing the Battery look over the terminals good, and keep the Terminal spacers if there is any.Just a couple of Ideas to get you started. post up when you can.*Jimi

Utp887,I didn't see your [second post].We are down in Daytona for a few days, been kinda busy here good grief crowded here. Anytime the BAS(Bank angle sensor is shorted the system shuts down the [fuel] and will not prime or start till it is reset.It will turn over till the battery is low but won't start.Reset the Bas and fuel should cycle back on, and the Interactive Exhaust [may] need to be replaced.
These servo Motors on the Exhaust Actuator do not last long maybe 5'000miles or so and are cheap built. Didn't figure you had a [BAS problem] due to your [first] post. Anyways the Inneractive Exhaust won't keep the Bike from starting but will cause the Engine light to stay on & Driveability issues and loss of power, with some coughing and throttle related problems since it controls the Exhaust Valve inside the Muffler.I have removed the Battery Terminals when that has happened to someone dropping their bike for a few minutes then reinstalled the Terminals and cycled the Switch to off and on couple of times.
This doesn't always work due to not sure how you shorted it to do that code.
Someone here on the forum should know how to reset it, I use my computer so post up if you find a different way to reset the Bas without todays modern Computer.I'm sure someone has done it manually.Good Luck.*Jimi

Hi Jimi, Thanks for posting also. I got the wild hair to check the batt voltage after you mentioned that(thought hadn't occurred since I had just recharged the battery) and it had be cranking fine, just not starting; She read about 12.5V so 50-70% charged not really taking into account any type of load test or Amps... The bank angle sensor tested fine also; Read 5v on the red and green wire disconnected and 1.4 connected(green); the Fuel pump started to prime on its own for some reason?? So there may be an intermittent pump on my hands but for now I'm gonna have to wait till the morning to get a new battery I'm sure and see what happens. Hopefully its not the ECM But I'll know more in the morning.
Ok, so it's taken a while because i was waiting on an ecmspy cable to get in. Since our last conversation: I have purchased a new battery, ecmspy cable&software, and cleared trouble codes 21,33,44. Ecm spy mentioned that BAS was to high(because I unplugged it) and is now plugged in reading 1.1v; Exhaust was stuck open(also because I unplugged it), and fuel pump was shorted to ground... This one I'm not sure about.... How would I go about checking this issue? Also, the bike still refuses to crank... It was cranking fine prior to me unplugging the BAS sensor and not that the trouble codes are clear, it still will not crank.... Thanks in advance.
Relays? I keep posting this just because it happened to me. Ran great parked it and then it wouldn't fire up but I got different results when I switched them around. $6. At napa auto parts. Good luck...
Btw, it's the gray little plugs in the front left box...

I've checked all the fuses and cracked open the relays to see what they were doing.. All of them are operational, and the start relay engages whenever I press the start button. The only major ground area I've checked though is the one under the seat(battery cable to frame.) What others should I check? Thanks
