Dead ECU or not?

Please say, no Matty here's the answer all is okay  

OK, the real reason is the S4Rs knows you flirted with the stealth 1198s down at Eastern Creek, and is now making you pay 

Sorry mate, I know this is the place for real answers, but as I have none, I thought I might at least try to make you smile

Correct the bike will not crank if the immobilizer has the engine locked still.
But it cranks, there is spark but it just won't run.
Antenna has been checked as have the connections across the whole harness.

I don't think DNA can help me as I am in Australia but I might call our local importer.

Thanks for your input. 

You might want to consider getting the technoresearch tool.  I know mine has paid for itself and also has some entertainment value.

Thanks Goldfish, maybe that's true. She got me home from the track and said that's it  I'm done.

I'll take a look at the tool Bill, thanks for the pointer.

To further deepen the intrigue I put my DP ECU (not red keyed) into another S4Rs today and guess what?
It fired up straight away, so the diagnosis continues.
I think it is pointing toward an immobilizer problem, maybe the dash but then the dash doesn't show
any faults so I think my next step will be a Ducati Oz shop for a run on the DDS machine.

Stay tuned.

Have you checked all the grounds (ECU, Motor)?

How about all the connectors leading to and from the ECU, motor, gauges, sensors, ect?

Maybe when it started with the shops ECU...they just got lucky!?!?

[mattyvas]

Yeah they have all been checked.
I have been told to move a ground wire but I need to get some better allen tools to remove it.

Busy over then next few days so I'll have a go on the weekend.

Update to the story, bike is now in the hands of an official Ducati shop.
Mechanic has all the information I could give him and my previous shop had even called to give info.

My feeling now is that it is an immobilizer problem as I tried my DP ECU in another S4Rs and it fired no problem.
So everything seems to be pointing to a fried wire or something in the immobilizer system.
The dash is behaving normally, needles sweep like always, lights blinks like normal.
I am hoping it's not going to be the dash.

Hope to have an answer before the end of the week.

Had a call from George this afternoon (third shop the bike has been too) with the question, do you want the good news or the bad news.

I said well, the good news is it's fixed, the bad news is it cost $$$ to do so.
Basically I was right, fixed it is and in the end it was the starter motor causing the problems.

So reco-ed starter in and she's back to life.
I'll be going out Thursday to collect it so I'll let you know after a ride of course.
I'm hoping that this will be the end of the problems, after all the place it's at now is run by 2 of Australia's best Ducati mechanics.
It has been a strange problem to solve and I'm still not sure that all is right.
Seems washing it had nothing to do with it in the end but I'll now be ultra careful in the future.
