Yes!! I have it aswell!! I have charged the battery and have also swapped with my other Ducati just incase. The bike has been sat for a about 4 weeks as the weather has been pants. Now decided to finally take it for a ride and also the MOT is due...Anyway the battery needed charging as it had been stood for so long, once I had fitted the battery I turned on the ignition and there was no noise from the fuel pump. I checked all the connections and stripped and cleaned all the battery connections. Once again switched the ignition on and this time got the pump noise but the bike would not start!! If I switch the ignition on I get the noise but if I switch the ignition off and back on then the pump does not cycle.

I have swapped the relays about, both the ones under the seat and the ones behind the left front nose cone and it is still the same so thinking there is nothing wrong with them. I have also continuity tested the kill switch and that appears to be working fine. I tested the voltage at the pump connector whilst switching the ignition on and also when cranking the engine to see if it was still getting power, one thing I did notice was once the 12 volts had gone there was about 2v residual voltage left. this stayed on for about 5 seconds after the ignition had been switched off? (possible from the ECU) I did notice that when the engine was cranking the voltage was about 10v at the pump connector? Not sure what the limit is before it stops working?

I can also smell fuel so thinking it might be getting through? I also opened the filler cap and watched the fuel whilst switching the ignition on, it appeared normal....no frothing of the fuel etc...

Not sure where to go to from here?

Sounds like your battery had some invisible corrosion on one of the terminals. Had some on a friend's ST2 that drove us batty on a long trip. Bike just went totally dead. I probed for 12V and "found it" between the battery neg. terminal, and the neg. cable end!!!

Note: you can't turn the key off, then on, in short intervals to hear the pump. I believe you have to wait a few seconds (five or ten) between off, and on. If you're real quiet and listen, you'll hear another relay turn off during this pause.

 

[mw0dbb]

I worked that our aswell with regards the delay!! I can hear a relay clicking but not sure where it is?? Might be in the ECU? The terminals are now spotless as I stripped them down and took a wire brush to them!! I'm starting to think if it's worth stripping the fuel pump out and checking to see if a pipe has come off or if the filter is blocked?? I have never changed it!!!

 

[mw0dbb]

Can someone confirm what the immobilizer light flashes are?? I have a brief flash then 2 flashes then it stays on? Not sure if I had this before? According to the manual the light should go out to allow engine to start, I'm pretty sure it went out once the engine is running?

[mw0dbb]

A bit more progress but seem to be going backwards!! Charged battery fitted, turned ignition on but no noise, so had to reset alarm with key fob and then switched ignition on again, this time the pump primed. However the engine would not turn over!! I checked the connector at the solenoid but still the same so I measured the voltage at the solenoid with the start button pressed but no voltage showing.

I then stripped the start button switch down and cleaned all the contacts, at the same time I also cleaned the engine kill switch. Still will not spin up after this!!

I shorted the solenoid out to see if the engine would start but no luck either. It did turn over but didn't fire.

Not sure where to go from here? Wondering if the immobilizer is faulty or if the ecu is dead?? Are Ducati able to test the ecu without it being fitted to the bike??

The yellow immo light should not stay on , have you tried the 'Red' key ? , it is possible the Black key has become unrecognised.

The Immo also can fail (although rarely I am told) , I had this over winter a few years back on my '02 , the shop assured me it would not be the problem but after all else failed (including replacing the antenna ring round the ignition switch) they collected it and advised a few days later that a new immo had fixed it...

 

[mw0dbb]

Unfortunately I only have one key, would I get same sequence of lights if I disconnect the ariel lead? If it stays the same that might indicate the key is faulty?

Whatever the outcome I would seriously suggest getting another key (or 2) as spares (Not sure who from but someone on the forum will , make a suggestion , do you have the Code Card ?)

I dont think disconnecting the Immo will prove anything as it will just leave the key unrecognised which will not help here. whereas the 'Red' key would have eliminated a key related issue.

Until you can get the yellow light to off you are wasting your time tryong to get it to start as far as I know.

BTW - Did you refit the ECU earth , thats a common and easy omission.

 

[mw0dbb]

I suspect it might be an immo problem with the fact it won't start! I took the ecu out and cleaned the contact areas then fitted the earth on the side of the ecu closest the battery to ensure I have a good earth.

If it is a immo problem will I have to replace the immo and the key?

Your battery might be shagged John.
Although it's showing good voltage, it might drop to nowt when you try and start the bike.
Try swapping batteries over from the other bike just to eliminate.

 

[mw0dbb]

Did that Mark, it's strange as it was turning over yesterday!! Today it's not spinning?

John

 

[MarkST]

Ok. I guess you've also checked/cleaned all the connections around the starter motor and solenoid.

With regard to comments made about immobiliser issues, mine's gone reet proper topsy turvy. The immobiliser light used to flash when the bike was locked up and sitting dormant, and then it would be off when I was using the bike.
Now it doesn't flash when it's locked up and sitting dormant, but it does flash when I'm using the bike.

 

[mw0dbb]

I can't remember what the light did before? I'm sure it was on until the engine was running! I would definitely notice if it was on during riding. I have a meta alarm fitted, is this a factory fitted alarm? As I have one fitted to the ST2.

John

 

[MarkST]

Yes mine used to be on until the engine was running too, but now it's the other way round..

The immobiliser is factory fitted, and I also have a Datatool 3 which was on the bike when I bought it.

I have no starting or running issues other than the one I had the other day that I txt'd you about when I broke down due to the alternator/reg rec connection under the nose coming undone.

You dont have to replace the key to fit a new Immo unit but that is when you have a Red (Master) key - I dont know whether it is essential to have this to register the new unit (I think it is) but my shop said it was always worth carrying it when going away from home because the workshop will need it to access the electronics if a problem occurs on the road.

I had a Meta alarm but got fed up with it constantly draining the battery and was glad to remove it when I was tryng to solve a non-start problem. That turned out to be an incorrectly wired intercom.

There are upgrade chips out there (FIM I think but may be others) that do away with the immo so that might be another option.
From memory the new Immo was about £ 100.00 but is probably more now.

I'm thinking about taking the alarm off aswell, did you take the alarm off yourself? If so I do t suppose you have a diagram?

To remove the alarm first disconnect the battery.

Locate the main unit (was under the top fairing on the left on my bike)
Follow each wire (they are all black) until you locate where it is tied in to the harness then clip it off tight to the original.
Seal the open connections with tape.

 

[mw0dbb]

Is it really that simple?? Thing is if I don't reset the alarm before I turn the ignition on then the fuel pump doesn't prime?? I suspect this alarm is also tied into the immo circuit maybe?

I dont think the alarm is/was tied into the Immo directly but what happens , and what annoyed me eventually , is that the Ducati Immo sets itself automatically if you do not start the engine promptly (I think about 30 seconds) so you end up with a silly starting regine of:-

Process One:

Use remote fob to turn alarm off.
Turn ignition to 'On'.
Start engine.
Put alarm fob away.

Seems simple but if you get interupted (group rides are main culprit here) and dont start the engine the bike immo steps in (even with the key in the 'On' position)

So Process Two starts:-

Turn the ignition off , wait about 10 seconds for the bikes system to reset
Whilst that is happening get the alarm fob out again because that can self-activate as well (it is not waterproof so cant be left attached to the keys and BTW it is 100% worth having a spare fob battery in the tool box because I had to call out the wife once late at night when it failed after refueling)

Make sure the alarm is 'off' , I sometimes had to turn it 'on' so that I could then turn it 'off'

Then , when sure everybody was ready to go and the wife did not suddenly decide she needed to do something and delay the process again , start Process One.

I just got fed up with it , It was a Meta 361T I seems to recall.

Anyway , it is staightforward to remove but make sure you have the battery disconnected.

I was so much happier when that alarm was removed

Think I'm making a bit more progress, cleaned a load of plugs Sonera of which had some corrosion!! The bike now turns over but will not fire, it sounds like it wants to start so I pulled the vertical plug and it was bone dry?? The pump is priming so I'm starting time think I have a blocked filter or obese of the pipes is blocked??
