Technical 2006 Ducato 2.8 jtd starting trouble.

[Ralph Burton]

Hi everybody. I am desperate. 2006 Ducato 2.8 jtd (244). Was running great. Was stood for a couple of weeks while I fixed a drive shaft cv boot, change engine and gearbox oil. Came to start engine to get oil round and no deal. Engine cranks but will not fire. No warning lights on dash, no fault codes showing on diagnostic, no blown fuses, good battery. I haven't touched anything electrical prior to trying to restart following work. Not had anything to do with Fiats before and I only have one option remaining after this and that is a Fiat dealer. (I am not that well off) Thanks in advance for any advice.

Any chance when fitting CV boot if O/S you disturbed the crank shaft position sensor or wiring?
Does the rev counter try to react to the starter motor cranking?

 

[Ralph Burton]

I didn't know there was any wiring or sensors down there. Rev counter does register when cranking engine.

Probably not that then if rev counter is reacting to starter cranking.
Did you do anything on the fuel side that may introduce air into system, fuel filter or pipes etc.?

 

[Ralph Burton]

No. Drive shaft out and in. Air filter body out and in. (To refill gearbox) Didn't touch anything else. That's what I can't understand.

Strange.
Fiat dealer will probably want vehicle towed to them , so bill starts mounting
Any chance you have access to MES or another good live data type diagnostic tool.
This would show if good fuel pressure at Common Rail etc.
I assume battery is spinning engine over fast enough?

 

[Ralph Burton]

I borrowed a diagnostic machine from my mate. It's a good one but I don't think it's MES whatever that is. Engine is spinning well. I don't fancy the idea of messing around with a common rail system cos of the pressures involved. I'll keep looking for now. Thanks for trying. Cheers Ralph

MES (MultiEcuScantool) is what many on Forum are familiar with and use so can advise on results etc.
Not me, I use mates Snap On Zeus Professional tool or my MaxiEcu tool, the main thing is they don't just give error codes, they can run tests and read / store live data, such as the pressure readings on the Common Rail etc.
Some basic tools may not even read Fiat Specific fault codes etc.
I agree about treating the high injection pressures with respect, but with these tools you can get their readings from inside the vehicle without dismantling any pressure lines etc.

 

[Ralph Burton]

You learn something new every day. I'll have a look and see what I borrowed. It might be the business. I'll let you know.

The first two statements above, do not suggest a problem with the crank sensor, but from my own experience removing the air filter body is a bit of a hassle. I think that it is the crank sensor wiring that passes over the clutch housing in that area, but it could be the speed sensor wiring. In the absence of any other clues, perhaps a careful examination of the wiring that passes close to the clutch slave cylinder mounting bracket may reveal some previously overlooked damage..

Another possibility is disturbance to the pipes connecting to the fuel filter, which is mounted behind the air filter. However thes pipes are pressurised by the tank mounted lift pump, so more likely to leak deisel, than pull air in. Does the lift pump run for a few seconds when the ignition is switched on?

In regard to the initial post, confirm that the key code light (padlock symbol) illuminates, and then extinguishes, when the ignition is switched on. I do appreciate that this has most probably been done several times already.

Keep an open mind. The failure to start could be coincidental.

The abbreviation MES refers to MultiEcuScan, a software package which runs on a Windows computer. It perhaps the most frequently recommended diagnostic device on this forum.

Thanks for the info. I'll have a look in the morning. You're right about getting the air filter body out. Could have caught something and not realised.

 

[Ralph Burton]

The immobiliser light does not come on and go out when ignition turned on. No blown fuses. I assume, therefore, that there is a problem with the immobiliser. I don't know what could have happened.

I am afraid that the above does not sound good. Others faced with similar problems have opted to have the immobliiser function delated. However before starting on such an action, which has security and insurance implications, please see my post #6 on this recent thread, together with attachments.
