Ds WILL NOT START PLEASE HELP

My bike today stopped working . I have no ideea whats wrong with it .
Bassicly i started up as normal and i let it idle while i was closing the garage door , after about 1 minute it just died . I tried to start it again for ages and nothing . I had a look at the spark plugs and i saw there was some black stuff at the bottom of the plug , cleaned it and still didnt work ( both spark plugs )
Checked the battery cable was connected properly that is where i run out of ideas .
Last week i broke down in a river ( no petrol as the warning light dont work ) and i did tried to start the bike for half hour or so .
Would that have damaged the spark plugs ?

does it turn over and if so can you hear the efi priming

Sounds like your plugs are just shot.

I'd start there bro.

Make sure you have fuel and spark...if you have both of those, its prob not good!

the spark plugs are good . I really dont know what the hell is wrong with it . are there any sensors on the bike that trip ??
My dealer is away untill friday so there is no one i can talk to .

I made a quick video maybe some can shed some light on it

Same thing happen to my ds try unpluging the efi then plug it back in thats what i did and it started up right away.

any ideea where it is ? i unplugged and unplugged all the plugs besides one which is underneath the coolant tank and is hidden away its the grey one . I used some of gthe quick start spray and it fired away but then it died again . So its deffinatly something to do with the Efi

Check your fuses?

Sounds like you have fuel deliverly problem ,check fuel lines,petcock,maybe injector clogged.if it starts with spray starter fluid its running a second on that fluid then shutting down it sounds like fuel is not getting to injector or injectors clogged? just my thoughts GOOD LUCK!

It seems that i used a dirty container for fuel which deposited a some dirt in the engine , well put it this way im never using that container again .
After changing the petrol it started staright away
many thanks for all the advice
