i think your looking at the pump itself. It controls pressure delivery etc. My firend had similar issues with a transit and that turned out to be the pump solonoid having a mind of its own. Sods law the solonoid was part of the pump so had to have a complete pump. my mates partner had similar with a golf gttdi and that was the pump
Yeah i think ive narrowed it down to either the solenoid, sensor or wiring. Well im hoping it is or ive wasted a lot of time trying to look 
Im pretty sure if its the solenoid that you can take it off and recalibrate it, well if its not totally knackered. so im hoping its not an expensive fix. Will find out on Tuesday.

Well your pump and injectors have no problem making and sustaining pressure so that rules out the pump, injectors, fuel filter and lift pump hard to know what happened right at the end graph a second is a really long window between reading.
Graph intake air quantity, engine speed, boost pressure and actual egr.

Well thats something then, least it rules out some of the expensive bits
Heres the test you wanted to see, same runs as the fuel test down hill then up. was a little slower as there was a bit more traffic but was still quick enough.
One thing i noticed though, although it wasn't fixed it did seem to run a bit smoother when i ran this test, don't know if i found the van in a good mood or whether it had anything to do with it.
Im more leaning towards a wiring problem again, seeing that it doesnt look like it a fuel problem.
Well its in the garage soon, so hopefully you get to read it at some point today

I dont know if this is anything but ive been sat in the van on tickover for about an hour to keep me warm whilst i wait for a delivery to turn up, and when i went to drive round the corner it cut out as it normally does but when i restarted it, it smoked quite a lot, i had to sit there and rev the smoke through for a couple of minutes.
Well according to that you have no boost at all so you've blown off a hose or a hose has split or your intercooler has split or the map is stuffed / covered in ****e , less lightly is turbo wastegate is stuck open or come off the actuator. Check all your hoses and intercooler and take out the map and inspect it. If its really manky your intake is probably totally encrusted in egr gunk and should come off for a cleaning. If those readings are accurate you're in for a cheap fix unless your turbo has inhaled something and lost its vanes but thats way down the possibility list.

Thanks for looking at the graphs for me .. your a star
Now i just have to locate the map Will have a look at the hoses but not heard any blowing (if they do). But at least hopefully it will be a cheap fix.. Will see what i can do, if not i'll still stick it in the garage as they can get it on the ramp then.

Ok looking at the original fuel test, the pressure regulator has just tipped 56% before cutting out, the max number depends on the map in your ecu but 56% is the magic number for some cars with the same engine. By rights it should go to limp mode by dumping the pressure down to 340 bar probably dumping too much and cutting out.
So my best guess is what I originally thought the pressure regulator isn't working right, might be gone weak, might just be dirty, have swarf on the end of it. If you're taking it out you need to be make sure the pump is meticulously clean before you touch it you don't want anything falling into the pump.

Well it was booked in the diesel specialist today anyway, so i told them to look there, and they code read it and diagnosed that anyway. So they took it off and replaced it with another they had and the fault was still there.
So they think its the wiring, which was my first fear, as thats gonna be a bugger to find, they said it could take them 3 hours to find it..
Gotta make a decision now whether to let them do it or not now..

Unless it could still be the crank sensor?
Think someones trying to tell me to change jobs though. The other week i had a merc van on hire, EML kept coming on with the turbo going. The citroen relay i had on hire today, the alternator went on that.
Also this morning im driving on the A5 at 3am, its pitch black and this lorry keeps flashing me coming the other way, so im wondering whats up with him, as he keeps flashing. so i decide not to worry and go back to driving, only to find theres a bloody donkey heading straight for me luckily i wasnt going fast as id just come off a roundabout otherwise it would of been dead donkey

Its amazing what you can do with a 98 vehicle with a paint job and body/fairing/bumper kit his trucks and vans always look great.
The crank sensor could cause it to cut out but you'd usually have a code, theres some issue with the pressure anyway every part affect every other part so its hard to disgnose, theres actually no reason the pressure regulator can't run up to 95% duty cycle but the map in the ecu has a range of expected values and prevents it.
How much would the diesel fella charge for 3 hours. Getting another vehicle even a new one is such a lottery.

Yeah im not liking all the electrics either, but they are nice when they work
He charged me £54 inc. so i suppose for an hours work.
But now i have a problem. I drove it to work this morning about 30 miles, and it wet and cold and it drove ok i suppose. did my days work all 14 hrs and then went to drive the van home. It would rarely get more than 15 yards without the egr clicking and cutting out.
So i got some electrical spray and did a couple of connectors, still no joy. so did a couple of other things, and eventually it drove after a bit of a spray on the accelerator electrics, still cut out but got me moving. Had to stop somewhere and after a few more cuts outs i stopped again, had a wiggle of some wires under the steering wheel and when i got back in it. It went straight to limp home mode and now its stuck in limp home mode.
Turn it off and restart it, still the same. disconnect battery to reset it, still the same, even had the engine running and took the battery off, engine still runs (is that normal). even when i touch the battery connector onto the battery terminal there is no spark.

Stuck in limp mode is much easier to diagnose than intemittant! You need to check diagnostics again. I would never disconnect the battery with the alternator running, in theory the regulator has all sorts of protections but if there was any issue with the regulator without the battery the voltage could shoot up and damage the electronics. This is especially true with smart charge alternators like on fords which adjust the voltage according to load and if the load suddenly drops then can put out a spike of 18V+ The accelerator pedals can give trouble you can graph the signal an dgradually move it up and down through its range to check for spikes/inconsistency.

Ok here we go.. i think the first 2 are from before as they always came up.
P0380 - board relay, thermostarter,preheat,ecu - signal low
P0191 - diesel pressure control - invalid signal - light on
P0110 - Air Temp sensor - signal high
P0101 - air flow meter - signal low
P0191 - diesel pressure sensor - signal low - fatal
Now i did, undo the MAF sensor and the 2 plugs on the diesel pressure reg earlier, but the engine wasnt running.
