    I put a new Odyssey battery in that is fully charged. I siphoned out as much gas as I could and put a gallon of fresh gas in the tank. I changed engine and trans oil (I'll worry about final drive once it starts).

    I put in new autolite plugs.

    I get a spark from the plug wire when I ground it to the frame with a screwdriver.

    So I assume that my problem is fuel. I detached what I believe to be the fuel injectors from the intake tubes and pushed the starter button and I don't get any noticeable liquid jetting out of the 4 little holes. But I'm not sure if I should. I do get fuel from the tank at the quick disconnects, and I can here the fuel pump doing its thing when I turn the key on.

    The starter just goes round and round and nothing ever fires. It doesn't almost fire and fail. It just doesn't fire. So I think I'm not getting fuel all the way to the injectors.

    So how do I diagnose where the problem is and how do I clean things up so that fuel gets through. I'm just looking to get it functional enough to sell the bike. You take a big hit if you try to sell a bike that won't start, but I'm not hiding the fact that it has sat idle for 3 years and I'm recommending that any purchaser take it straight in for service, so I just need to do enough to get the engine to fire up.

    It has not run at ALL for 3 years? something that meters the fuel into the engine is gummed up. that is my final answer.

    Was changed immediately before the bike was parked for 3 years. I doubt it has had 10 gallons of gas go through it. Also, if the fuel filter were clogged, I wouldn't see gas at the quick disconnects, I think.

    Yes, I get that. But what? How do I go about diagnosing it and fixing it? I'll forgo the diagnosis if there's a way to just pull all the likely parts and clean them somehow.

    And no, it really hasn't moved at all in 3 years. It's possible that I started it a few times in the first year that it was parked, but once the battery died, it sat completely untouched.

    i said that because I don't know if it was carbed or FI. I looked it up and it is FI. So I am going to defer to someone that knows FI and injectors. If it was a carb, take it apart and clean it....but FI? Thats like magic to me! :lol3
    On second thought, if you can get to the air filter and drop a few squirts of gasoline in to the throttle bodies, hit the starter and if it kicks over? you have clogged injectors.

    on third thought....how come you haven't stated it in 3 years?! (I say that knowing my XRL is also gummed up...) hey, i have a Gold wing now!

    have you removed the air cleaner to determine if there might be a nest in that box ,
    possibly plugging the cylinders

    yes - when I separate the quick disconnects after powering it up (and hearing the fuel pump), I get a drop or two of fuel.

    I'll try cleaning the fuel injectors. That seems a likely candidate.

    If your QD are installed with worm type clamps you could remove the male from the return and install it in the female QD on the supply side and run the pump just to confirm. Or you could cut off the irreversible clamp and do the same. That would also get any remaining old gas out of the tank.

    It will turn over and not start with the side stand down.

    Do you have it on the center stand with the side stand up?

    Would he have a spark with the side stand down?
    Do you get a spark with the safety switch shutoff on the handlebars?
    Just wondering.

    I would start at the tank. Remove it and clean it of old fuel after you remove the pump plate.

    Next, inspect and replace the likely cracked rubber fuel lines making sure you use replacement lines that are submersible in gasoline (SAE 30R10 rating).

    Next, replace the fuel filter.

    Next, blow out all the vent lines noting their connections (don't reconnect wrong).

    Refit the tank and fill with fresh fuel to which you add some fuel system cleaner (Techron is used by boxer owners). Energize the pump and determine if you have pressure at the injectors (43PSI).

    Clean the injectors of old fuel and varnish. Replace the filter screens in the injector inlets. Refit the injectors insuring that the o-rings are secure.

    Start the engine.

    Report your success here.

    do you have an alarm on the bike ? I tried starting my GS after sitting awhile and forgot to turn off the alarm. Experienced same symptoms you describe. Turned off alarm and bike fired up. :norton

    First make sure you have fresh fuel in the tank. Based on the symptoms that you have: spark but no fuel at the injectors, here are some possibilities:

    --no fuel pressure. disconnect return line going back to tank. press check valve on hose connected to fuel distributor and point into container. turn key on, see if any fuel flows.

    --inside tank hose split, pump failed, filter or screen clogged. open tank and diagnose.

    --clogged injector. remove injector carefully from fuel distributor (they break easily). point distributor head into container, turn on key. should get very strong stream of fuel. if injector clogged remove and clean, (maybe ship to outside service)

    Disconnect the line from the injector and point it at a bucket, turn on key. Trouble shoot it just like an electrical circuit and start at the source/ work your way out from there.

    On the 1150 you can slide the air box tubes back off the throttle body and look down to see if you are getting a spray.

    Is the exhaust plugged for storage. I used to use an exhaust plug from a motocross bike to keep junk out of the pipe. I always forgot it and the bike would not start with it on.
