    More and more I am thinking these pump/injector issues are clogged filter issues.

    The great state of confusion
    When the dealer replaces the fuel pump (unless I'm missing something) they are replacing the entire assembly, using P/N 16 14 7 723 151 (for ~$500 USD). The assembly includes the fuel filter so ...
    root cause: filter vs. pump is not known. :cry

    If you are out of warranty and paying out of pocket, imagine the cost of an alternator, a fuel pump, maybe a fuel tank, and a cam chain?
    Do the math and you are looking at the cost of a good, clean, used bike.

    Just got the latest info on the bike in question... New fuel pump and controller were put in. Reprogramming done. Fuel injectors cleaned and working properly. They test rode it for 3 hours and seems to be working fine......Time will tell. Thanks to all for the input....

    That would have been about $800 bucks right there, no?
    Now, imagine the time and expense importing the items into a 3rd world country.
    The F's are a risky idea for an RTW bike.

    My 800 has been starting a little slower lately, so I thought the battery might be getting weak. Load tested it at 13 volts. This morning I cranked it over and it burbled like it wanted to run, but wouldn't catch. Battery was happy to do a lot of cranking, but no go. It's low on gas, but I've run it down to 9 miles remaining before and it says 21 right now. I dumped in a liter that I carry as a spare sometimes. No joy.:cry

    I run Chevron gas about half the time, dump in some Techron if I haven't been. Also dump in some SeaFoam if it's going to sit a while. It did sit a couple weeks, but I've ridden close to 200 miles since them.

    I'm going to tap the injectors, then try the battery charger trick when I get home.

    Any other ideas :ear?

    Sure!
    This could be a classic case of an ailment not covered by Obamacare.
    It might be time for bypass surgery.
    Cut, slice, and splice the bypass around the Fuel Pump Controller.
    If you ain't smelling gas, you'll be payin out the ass is the Motorrad expression for this one.
    Fuel Pump Controller goes south, you are stranded unless you bypass it or happen to have a $150 spare part in your tank bag.
    Google the following, "Tim Cullis fuel pump controller bypass" and give it some thought.
    Mine went with no warning last Saturday and not under the most ideal circumstances. But thanks to Tim, I was able to ride it home and order a new one.
    Just before you snip those leads, be real comfortable with your troubleshooting skills and splicing into thin wires ability and think manly thoughts and remember there is no going back.:eek1

    Thanks for the input. Reading this thread, I was fearing the pump controller and may just pop for the Burns Moto fixer cable as a backup. Me and solder, we just don't get along too well.

    However, I went home for lunch and the sumbitch started :huh. I'm a little afraid to ride it anywhere and park it, though. Should have some time over the holly days to mess with this.

    Hell no! Don't do that!
    Start it up and ride to the BMW dealer, ask kindly for an old fuel pump controller that has gone kaput.
    Gut it and roll your own cable like on that link to Tim's method.
    Then you can zip tie it to a handy spot under the seat along with a nice little T-10 key and if it really does go tits up lights out on you, you can impress anyone standing around with your mechanical know how and wizardry and solve the problem in about two minutes.
    With great knowledge, comes great power, it might even get you laid!

    I think the same shit just happened to my ride. Hadn't started it for a month or so, went to start and battery was dead. New Odyssey battery so gave it a good charge and started no probs. ran it for 15 and shut off and restarted after 30 min no problem. So decided to take it for a spin for about an hour as it wasn't snowing or pissing freezing rain.

    Got about 40 miles and stopped for a coffee. Tied to start and no dice. Battery was strong but it wouldn't turn over. Have had sidestand switch issues in the summer but that was in knee deep mud and water. Understandable there. I hosed the switch area with my water pack to see if that might have been it. No dice. Shit. It was Christmas Eve and I had to be at a dinner with family. Bad timing for a quick ride to go south.

    Had to abandon the bike for a few days and make my way home. Sucked. 4 days later had it towed home and it started right away no problem. Sounds like the same issue and am afraid to go out again til it's sorted. It's a 2008 so well out of warranty. Am going to go through all these thread posts a couple more times and hopefully all the good suggestions will house the correct one for me.

    I can't blame the bike cuz I've put it through hell and its been golden. Payback time perhaps.

    Mark.

    There are a few threads here there will show you how to ping the injectors..... That would be good to do, as it sort of blows out what ever gunk there are in there, then several tank treatments of techron. That would be a great start.

    It's also a good sign to perhaps invest in getting a GS911.
