    Default Bonneville not starting....

    So I am trying to put a 2008 Bonneville back on the road after being dry stored for 5 years.

    The engine turns over on the starter motor.

    It has a spark. I removed one of the plugs and it has a spark when it is trying to start.

    So it must be fuel right?

    So does a fuel injection system need to be primed or anything?
    I hear the fuel pump turn on.

    If it was a carb I would just take it off and give it a clean. But I have never touched a fuel injection system before.

    I'd drain the tank and try fresh fuel. Good stuff, not council house spec.

    Agree with above, modern fuel does not store well.

    The tank was dry. I just put ten litres of fuel in it.

    Still won't start.

    Any one know how to read fault codes on a modern Triumph?

    Battery was out the bike for teh five year period and I just put a new freshly charged one in it.
    Would that have anything to do with it?

    No idea but its worth pulling the pipe off the fuel pump and make sure its actually moving fuel. I had a CBR6 that had stood for 8 years, the pump whirred but was properly clogged and couldnt draw petrol. once that was sorted it started easily without touching the injectors.

    TuneECU lets you read fault codes and so much more. Windows software is free, cable is about 10. Not the most straightforward install/setup but once it's up and running it's fine. There's an Android version too but you have to pay and I've no experience of it.

    Does it have a factory alarm / immobiliser?
    5 years without a battery would kill it's internal battery and it may have failed.
    If it has got one, remove it and use the jumper plug just to remove one potential variable.

    No, no alarm.

    I'm beginning to wonder if the injectors are blocked or a pipe has become blocked or something. I'm thinking to tip soem toluene down the fuel line to see if that helps.

    When the engine cranks I get a spark at the plug.
    The engine spins over resulting in exhaust air.
    But it is just air coming out, no exhaust gasses, no smell of petrol either, just air.

    Is it a new battery? Either way, jump start it. I cant' remember exactly what it is but they wont start unless it has a strong battery. ISTR people on the Triumph forum getting pissed off about them not starting after winter storage despite being on batteyr tenders.

    Try easy start. If that starts it then it's fuel. If it doesn't it's something else.

    You do need to be careful with fuel injection as it runs at fairly high pressures and you don't want it squirting in your eyes.

    I was about to suggest the same....you may find that once its started on a squirt a couple of times it will run. If not, fin the feed from the tank and check , as Chillitt said for fuel.

    So I pulled the tank off and disconected the fuel pipe, turned the bike on, fuel pump whirred and sprayed fuel everywhere.
    So the bike has fake carbs with injectors in them. So I tried to fill the fuel pipe to see if it went down?
    It didn't.

    So I worked out if you connect the injectors to the battery they open.
    So I put some toluene into the fuel pipe and manually connected them to the battery and opened the injectors. The fuel went down.
    So after doing this a few times with both injectors, the wife came out and asked me why I don't just try and start it now? So I pressed the starter button... POP BANG a little bit of smoke and brum brum.

    So the bike runs now but the engine management light is now on.
    I'm thinking a sticky and dirty injector?

    I had a OBD2 reader for the wifes car and wondered if it would give me the fault codes.... P0201 and P0202
    Yup you guessed it fault with injector number one and two.

    The injectors were running fine five years ago and with no use they seem to have packed up?
    I wonder if they just need a good run and some toluene mixed in with the fuel to clean them out a bit?

    If not a new set of injectors may need to be ordered after I have checked all the wiring.


    Thanks for your help guys.
