most fiat scudo van owners woludnt care in my experiance tho. they drive them to destruction, the only time you see them at a garage is when they die by the side of the road.
did you do a leak off check then before?
id get all the injectors checked, serviced and rebuilt. being an old school pump driven engine if all the compressions were correct itd be obvious the injector preloads werent firing at the correct pressures.

Yeah i took another reading just of no1 injector and used it as a reference.
This was one of those jobs when i really could have done witha couple of extra channels. I use the reference waveform function quite a lot, that can sort of make up for it but it would have been nice to have the fuel pressure regulator duty cycle in there too.

Its a common rail, and like i said, leak off check didnt give me enough info to make a confident diagnosis. I'm not going to spend a couple of hundred quid of a customers money having work done that only 'might' fix the problem. |

common rails don't have leak off pipes as such. infact ive not seen electrical connections to the injectors on them. what year van is it?
:edit: apart from a reference injector that is,

I work for myself. I'm a NT at a local garage, but as a subcontractor rather than an employee.

To get a standard A40 this low, you'd have to dig a hole to put it in |

I'm not....
I thought common rails tended to have both electrical connectors and a leakoff pipe. At least, there is a small pipe on the side of them which connects into the fuel return...

Indeed, EDC rotary systems have a reference injector, but they also have leak off pipes. In fact ive never seen a diesel that didnt have leak off pipes.

itd be similar to the bmw engines in landrover freelanders... looking at the injector cylinder smoothness comparisons then? whichever is out is your problem.
are they run off the cam like modern vag stuff? or ford stuff with a separate high pressure pump?

Bosch cdi4, common rail direct injection. Not PD units like you find in a landrover or some VW's, But common rail where all the injectors connect to a common rail. I hear its quite popular on a lot of cars at the moment. |

common rail vag stuff don't have leak off pipes, the rail is in the head itself, high pressure genarated off the tandem pump on the end of the head run off the cam. injector period desided by the ecu and final pressure set off by the big injector rockers run off the cam lobes. leak off is not needed..... ford and fiat stuff is different. lastest ford i looked at recently was a 2004 2.4 tdci transit the cam retainer/rocker housing part of the head had broken u needed a new head and went to ford. that had leak off pipes but that had a separate high pressure pump run off the timing chain but wasnt a rotary pump.
like i said i see vag, bmw stuff most days, merc stuff not so often and thankfully italian and ford wibblepoo less than that.
