Fiat Ducato RHV 2004 - Non start #

Posted by Rob Gardiner on February 19, 2010, 8:54 am

Year of Manufacture *: 2004
Engine Code or CC *: RHV
( Optional ) ECU Type: Bosch EDC 15C
( Optional ) Scanner Used: Bosch KTS

Hi guys, I wonder if any of you can help.
Vehicle will not start.
Compression on all cylinders is 400psi.
Good flow and pressure from lift pump.
350bar at fuel rail on cranking.
1300bar direct from the pump on cranking and holding around 800-850bar.
Glow circuit working ok and new glow plugs fitted.
Injectors were removed and tested on our Hartridge bench tester, backleak wasok but none were firing below 400bar so new injectors (0445 110 076) were fitted.
Timing has been checked and double checked.
Diesel has been drained and changed, filter has been renewed.
Inlet and exhaust tracts have been checked and are clear.
The ecu IS firing the injectors but is it possible they are not firing in the right order for some reason?
Anyone had any immobiliser issues with these?

Any info appreciated

Rob.

Hi

Will it run on a sniff of easy start ? e.g fire and die or continue to run on own ?

Cheers Aidan

Hi Rob
Have you checked Cam/ crank sensors ? what happens if you give it a light spray of easy start ?? might just be air trapped in system
Regards Peter

It will fire up and run on easy start but won't run on its own.
I have removed and resistance checked the cam and crank sensors which seem to be ok but have have been unable to scope them.
I'm guessing this is the only way forward?

Hi Rob
There might still be air in system, we normally loosen injector pipes & crank until fuel comes out.

i've had immobiliser problems with a citroen relay (same van)
if the immobiliser key symbol doesn't go out when cranking that's where your issue lies
if you have the imm. code from the car pass you can check by going into engine ecu on scanner & entering the code as prompted under emergency code start procedure or something like that, if it starts then you've got immobiliser control box issues

Hi rob

When cranking, do you get un burnt diesel i.e smoke from the exhaust ? How did you confirm injector are switching ?

Cheers Aidan

Peter:
The vehicle is a Bosch common rail system so cracking injector pipes isn't really an option. They do tend to self bleed pretty quickly though providing the low pressure supply is good which it is.

Steve:
I was thinking around those lines. The immo light isn't staying on though and no immo related fault codes have been logged. I may look into this a bit further though and try what you suggested as I'm convinced it's electrical.

Aidan:
I have had each one out individually, turned around and re-plumbed into the vehicle and firing into a see through test cylinder. I can confirm they are all firing diesel. I have also bench tested the injectors on our Hartridge machine at pressures accross the board. All good.

I currently have the ecu away being tested so fingers crossed it may be causing the issues.

hi
I can't see it in your post but is there cam-crank synchronization?
