Starting issue

been chatting to the us seller most of the night but he wont budge on price or give any me any assurance it works ... he dropped it $20 but still gonna be $280ish + any tax im hit with .

I may have found one though .. localish and cheapish .. and marked as working ..but not been able to speak to him to confirm details
 
Well ordered ecu .. only time will tell if it works but looking good . Will get it fitted and if all ok will get it up to grifs for a full tune and RR as i think my map on my pc3 is **** .. I mentioned my at the wheel bhp and griff nearly had a stroke as he was laughing so hard :p

At least i should get up to Brackley Bike fest
 
well new ecu arrived... fitted



And














And





NOTHING !! grrrrrrrrrrrrrrrrrrrrrr

I checked the voltage of the battery (proper digital meter) and after 24hrs charge i was getting 12.8v ignition on .

Trouble is im getting 9.5v when turning it over . Now i know it takes alot from the starter so maybe 9v is fine but to me it seems abit low . Once or twice it wanted to start and gave abit of a cough but nothing more than that

Now do i change the battery assuming thats the issue or do i have a duff ecu or summit else ?
 
I would have expected around 13.5v dc after a good charge.9.5v is certainly not enough oomph to turn over the motor and power the injection system.Try charging the battery again,....if you get the same result,mebbe its knackered.
 
It Turns over fine .... But gets 6-7 good spins then starts to falter .. Lowest i seen on a crank was 8v . Battery looks to be £45 on the bay but have a mate in the car parts buying dept so have asked him to get me prices . Will also pop in 2 plugs as well just to be safe ..

I might try a jump start .. will maintain the voltage i need to prove it 1 way or another .. Just hope its not the replacment ecu
 
new battery and plugs here .. battery on charge so hopefully we shall know tomorrow !! £37 all in the for the battery and plugs so happy with that !!

The cam sensor and the fan relay share the same power feed circuit as the injectors, might be worth having a look at those connections.
I've got a vested interest in whatever outcome.
 
As a wee side note, a got ma bike Dec 08, it wiznae ridden at all fir a least 3-4 months, it's sat in ma garage noo fir ower 3&1/2 years and never bin on an optimate or charger. The battery has Never been charged or disconnected from the machine by me and it still fires up.....

Advice is (**** Knows).

Hope yer get sorted SOON mucker.

BTW it's now done ower 15,500 miles worth of Major Grin Miles.

Yer Like whit yer like and even though these machines can be fickle, that wid Never Stop Fuds like us Grinning.:thumbup
 
Dont think its ur battery mate, mine is a facefuck to start and the problem is electrical on the charging side, ur bike is turning over 5 to 6 times u say so that would suggest charging and batt is fine. When my battery is charged it starts first turn. Deffo sounds like a fueling/ECU prob dude!
 
Well todays the day that it shall all be tested . I have been without internet for the last day or so and my charger was knackered so could not charge the new battery .

I could probably find the fan relay Aldo but no idea where the cam sensor is . care to explain the location of it ?

Just because the engine is turning over does'nt mean the battery is good.Dont forget it still has to power up the fuel injection system and ignition.
To double check the battery,...take it off the bike and charge it up.Make a note of the voltage,....expect around 13v dc.Leave it 24hrs and check the voltage again,....any drop in the volts 1.5-2v,....and there is a good chance the battery is on the way out.
 
Well new battery is 13.5v after a 4hr charge .. old battery is 12.4 after 2 day charge . I had this issue with my mondeo .. Battery would crank the engine over all day but would not fire . Jump it and would start fine but would not restart . Battery was at 11.9 v after a charge . Swapped battery and no issue since so i def think its a case of to low a voltage .

As i mentioned in my other posts when cranking the engine im getting low 9v on the crank and while its cranking it has to power the ecu/relays/injectors /dash on 9v . Im confident the battery will fix it .. But checking the other stuff first
 
well swapped battery and !! nothing .. felt like it wanted to start but was having none of it . just changing plugs now .. one throttle body rubber seems badly perished .. which is kinda weird . gonna check the crank sensor and relays

Its stinking of fuel so thats a good start !! once i get the plugs out i will swap and check for a spark . anyone got any other things to check ??

...sorry you're going through all this **** mate....

Ok...since we're straw clutching here...

Here's an easy one...swap the air pressure sensors over, one is under the seat, the other is on the l/h side of the airbox....incorrect reading from the a/p sensor will screw your starting up....it's a 15 min job to swap them over....they are identical (same part No)
 
Can you explain abit more Tifa ? also just check crank sensor and the connector was full of oil ? atm i have the airbox off and when i put the ignition on i get no fault . Also where will i find the fan relay ?
 
right the plot thickens !! just checked onboard diags and getting 0505-44 error which is a stepper motor issue and dash errors of dsb 01/02/03 and 04 which are all imobilser issues wtf is going on (this is with the new ecu btw ) helllllllllllllp!!

EDIT: ok stepper motor fault will be because its still connected to the airbox heheh .. still does not explain the imobilser fault

EDIT 2 : ok seems it needs a cross in the box to indicate an error so all mine show 0 0 so i think thats fine heheh

Good fun this !! NOT!!
