999 Flooded Help !!

Are you grounding the spark plug when testing?

 

you dont need to be turning the engine that fast to get a spark. lift the rear end slip it in to gear and with plugs out but in the coils/h.t leads turn on ignition get someone to turn the rear wheel. sparking? if so, you have just narrowed it down. :smileys:

 

I heard almost the exact same circumstances from my main dealer when they were trying to solve why a bike would not start, also a Multi. It turned out to be the starter drawing too much current in the end after trying almost everything else to solve the issue. Once changed the bike never failed to start.

 

so your saying you tested both cylinder coils and don't have any sparks?

 

yip.

 

and is the spring needed to make the connection from the coil internals to the spark plug nipple ?

 

Don't think there's a relay for the ignition system but there's a fuse for the ECU...

 

not necessarily as the voltage will jump a fair distance, but would be best to have it in there. hold the plugs in with insulating tape wraped round plug and coil.

 

Ok, so if its not sparking, Crank sensor, immobiliser, or ECU faulty? where does SD go from here?

 

need to know if its a good spark or not during the crank cycle and if not will t spark by turning the engine via the rear wheel.

 

I had prob with 999 start. The crank position sensor gap was too big. Whipped the horse shoe shim out from under cps. Sorted

 

Which plug end??
It's the body of the plug that needs to earth but Zimrurel

Surely that's fixed and is not something that would change over time, so is not something you'd normally adjust...

 

could be wrong but if the pump starts working during cranking after the initial prime it suggests it's getting a crank signal.

 

My bike would just turn over ocaisionally start. Glen, Moto V advised me to remove it. Safe to do. Remove screw, raise cps, it wont come right out. Whip out shim. Refit.
My bike is 05 999. A lot of bikes at that time were over shimmed. Starts fine since.

 

Id be double checking the gap to the trigger wheel to make sure it's not making contact with it.
I fitted mine with a .6 mm gap.

 

I was told not to worry about it by Glen.

 

yip. remove shim if your worried get someone to crank it while you push it in. you will feel it touching the phonic wheel. before i diagnosed mine correctly i filed it so it would go further in. (common fault with punto diesels same sensor i think or v.similar at least)

 

Apparently there's a tiny fuse located just behind battery box. It is for immobiliser. Worth checking inc the ECU Fuse...
