Ducati injection trouble shooting

**Voltaire** · 24th January 2011, 22:43

I went to start the SS the other morning and it turned over ok but would not start.
Today I pulled the ht lead off fitted a plug and it sparks ok.
The fuel pump whirs into action when you turn the key on.
I'm going to have to get a manual....
But firstly...has anyone had this ?
I ride it eveyday....except this week

over the winter it would do the odd cut-out-for-no- reason....but then it would start up and run ok...did it at odd times, once three times on way to work then not for weeks. I went thru and checked/cleaned all the connections I could see...some were a bit green.
thanks for any help on this.

Check the connector for the crank position sensor - left side of engine

**Voltaire** · 25th January 2011, 09:12

yes, when it wouldn't start I just walked away..... carbs and points I'd have a look.....
I'll have a look at the sensor, cheers

The ST3 had this a while ago, it was a stuffed battery, the bike cranked over ok, there was spark etc, odd I know but the battery under load was the issue, it could crank the bike fine but ther was not enough juice left for the ECU to run properly.

That's a good call too - was talking to a mate this morning who had that same problem. So +1 for battery check. Also worth checking the main earth on back of engine is clean and tightly fastened.
It could also be a dying/faulty ECU, but let's hope not.....

For anything electrical - the flowchart linked to at point 3 here should be your first step. You can end up checking all sorts of things only to find it was a simple charging problem.

sensors on ducatis are pure crap

apparantly some fiat car parts fit

you are on the wrong website

try ducatisti uk website - a load more information there

Yep, that site and ducati.ms if you can't find answers there I'd be surprised

Sell it and get something reliable (any jap brand)

**DEATH_INC.** · 29th January 2011, 18:51

On a jap bike it's 'unreliable', on a Ducati it's 'character'
Mine once stopped for no reason at all, and wouldn't start, so we dragged it home in the back of a van, got it out and it fired straight up, and never did it again.
My workmate has one at the mo, I rode it out of the shop the other day and it stopped dead, and wouldn't start again. After an hour or two's rest it fired up no worries, been going good ever since.
Maybe it needs a sleep.

have 2 ducatis in the garage

both are more reliable than any jap bike I have ever had

simple motors, easy to work on, changing cam belts is a doddle compared to cam chains which need constant adjustment, and are a pain to change

Easy to work on? only an issue if you have to "work on" your bike.
I guess thats why you have 2 ducati, "work on" one and ride the other
Personally I prefer a bike I dont have to "work on"
Considering you will likely change 5-10 sets of cam belts to one cam chain you would hope it would be a doddle.
And lets not talk about the cost of all those belts compared to a chain

Wrong website.....true, how about:

I tried buying a part for my Ducati here but its a rip off so I bought off Ebay, and rego is too much thanks to all the F*&ken cagers, and there are too many cops and no one waved at me....

I've bought a manual and have had a look on the UK Ducati site, cheers.
