1198 huffing and puffing ???? help please

[jerryz]

A friend of mine in Thailand has brought me his 1198 to fix as Ducati dealers wont touch it being a grey import ,,they are bastards here in Thailand they also wont fix bikes not bought from them !!!!!!

he is desperate for help ,, I guess im his last hope !!!! poor sod .

the bike is a 2009 1198s in mint condition and it has been running but has been standing for 4 months ,, it has fresh fuel in
it  cranks over OK on the starter and bangs and farts once or twice in the exhausts almost runs , and thats it smells like its then flooded a bit

Battery seems OK gives 12.7v dash shows no alarms and immobiliser is not the issue ,,

anyone got any ideas ,, im going to clean the injectors , test the coils and plugs and try my JPDIAG and see if i can reset the TPS etc

some people here have mentioned crank position sensor may be an issue he has one on order ?? but Im not sure about that ,,,

was it running fine before parking it?

4 months should not be enough time to cause a problem from setting, was anything done to it or is it 100% stock? If you can test the injectors and coils I would. also make sure to check fuel pressure. I doubt that an injector would clog in that time and for it to have the symptom you are mentioning you would need both to have clogged.

Crank angle sensor could cause the problem, do you have spark and/or fuel when cranking?
if you remove the air filter and crank it can you see fuel spray from the injectors?
With the plugs removed and grounded do you have spark?

A fouled set of plugs will give you fits so make sure they are good as well.

I would replace the fuel filter and then the plugs . . . Had similar issue with an 848 that had been parked for about 6 months and with about 1/4 tank of fuel, Panama is as humid and hot as Thailand, so, you can imagine.

Never used JPDiag . . . I would recommend trying to find an aftermarket shop that has the Socio diagnostic system, at the time of the 1198 it was the OEM system for Ducati in its tablet form

Or, check it out here, http://technoresearch.com/index.php/products/diagnostics/socio-complete-kit

yes bike was running OK before storage ,,, probelm in thailand is that no independent Ducati  shops exist that have  Mathesis or  other diagnostic equipment , only main dealers  and they will not touch the bike ,,, I also need a workshop manual  download for the bike ,,,

plugs spark ok , the bike actually fires  up,  turns about 2 or 3 times and then dies ,,,

Does the fuel pump run for a half-second or so at key on?

[clubhousemotorsports]

Sounds like it is starving from lack of fuel. I would check fuel pressure if possible but as speeddog said make sure the pump is at least running first. 

When you say it turns two or three turns do you mean crank revolutions or seconds. I would not call two or three crank revolutions running but at least you are hearing the bike make combustion . If so this should rule out things like immobilizer, mechanical  or ignition. 

Has anyone tried to use a non-ducati software on the bike? I have not used JPdaig yet but am familiar with similar programs. They are great and i am glad they are out there on the market BUT they do give you enough rope to hang yourself with. If a connector is reversed I have seen them blow the ground inside the ecu, often when this happens the bike will run. Poorly and very rich but more than what you are describing so it is likely this is NOT your issue but possible.

The injectors can indeed become clogged after 4 months sitting especially if the fuel has any moisture in it or is not top quality. The crud does sink, you know!
I would put money on fouled injectors.

[clubhousemotorsports]

lol.. not saying it is impossible but that would lead about every bike in the snow belt to have issues on a regular basis.  I have dug out bikes that have been sitting for over a decade and had 90 % of them fire right up, there was a bike or so that needed a tap on the injector due to it being stuck but even when I see bikes with bad gas in the tank often the gas in the fuel lines at the injectors is fine.

Yes to the statements in bold-yellow, as far as diagnostics, I can only recommend what I've used; other equipment out there: http://www.motorscan.com/ and a good bunch of Chinese "clones" of other OEMs . . .

OK have had a good look at the bike with JPdiag and tools ,,

due to language problems ,, It seems the last time the bike was running it died in third gear like it had run out of fuel ,,,,,it has not run for 4 months ...

bike is a 2009 1198s unmodified with 14k miles
the coils are OK , so are the plugs , big fat sparks , and they are dry
the fuel pump works ,,,,,
the immobiliser is OK
all fuses are good
all lights ,horn , and dash work fine
starter is fine
battery is perfect
fuel is good when we drained the tank
all mechanicals are good ,,

JP diag gave me some faults

1.......fan on right side , ground fault not working ,,, left side fan is OK working good
2......A & B injectors not working Ground fault ??
3......crank position sensor open circuit ?

still investigating dry spark plugs seems to indicate a fueling issue ??  but the bike just died last time out ?

I think its a fuel issue as i have  cleaned all the earths ,, now no fault codes  but left hand fan still not working  and no fuel getting to plugs ,,,,, all relays are OK as i took them out and tried them on my S4 and checked them on a test rig ,,

have told owner to get a new fuel filter  and some injector cleaner  ,,,,  thats next step?

I have requested a JP diag license for this bike to unlock service/tps reset feature as my existing one is for the S4 which is less sophisticated .

definitely a puzzle though  it almost fires  bang 2=3 times   ,, but plugs are always dry as a bone when examined

[jerryz]

good news  [drink]problem solved whilst putting in the new fuel filter i noticed a cracked rubber hose on the pump body a tiny split , which must have been causing a loss of pressure , once that was changed for a new 30mm of hose the bike now runs fine ...goes like bat outa hell.


however  :-[the headlights are not coming on after reassembly ,, all connectors are OK and so are the bulbs and fuses ,, and 3 main relays ,,starter,injectors and fans


is there another headlight relay on 1198 ? if so where on 1098 its on the headstock sub frame but 1198 is not same

Great that bike is running  . . .

Now, you sure ALL plugs are in? Were the headlights coming ON before?[just making sure] Have you fiddled with the LH control?

Check fuse for continuity OFF bike with multimeter, at times[and you know it] they "look good" but are actually defective, plus, headlights and front turn signals run through the dash in these bikes.

So, double check your dash connections and related fuses

[jerryz]

all fuses checked off the bike with multimeter   and all connections seem good ,, lights were working before ,, this bike is a japan /Euro model so  no lights off switch ,,,turn signals are working OK

[Speeddog]

I'm pretty sure XX98 controls the headlight relay via the ECU/dash.

Had a customer 1098 with intermittent on all lighting.
Bike got tipped over and totalled out before I could sort it out.

[DarkMonster620]

If all looks OK, then check the bulbs themselves . . .
