Fuel Issue: Trafic 1.9DCI 100 (04r) | Injector, Pump & Solenoid Replacement | Errors DF192 & DF208

Hello, for some time I have a problem with traffic, about half a year ago stopped firing in the morning and fired only on "haul". Later he couldn't fire at all. He was out of service and after 4 months it was time to reactivate. And here the problems begin when pulling the injections, one broke and the heads had to be removed. Now the traffic is being folded and replaced with new ones:
-4 injections
- pump after regeneration
- solenoid (pressure control valve) for a new one

But to keep going doesn't fire. After connecting, it displays errors df192 (fuel pressure sensor), df208 (solenoid) as permanent (cannot be removed).
And now I have checked everything, i.e. cable resistances between plugs and computer, all power supply, mass, etc. I have no idea, I mean, I have to buy another computer and replace it and see what will happen (the fact is not really want to buy it, but it's difficult ) Smile. But maybe someone has a different idea?

I will add these pressure valves and sensors on the strip, I have several and each has the same errors.

I have already spent a few hours on this and stepped through everything with the help of ICT.

See if it snaps from a cake.

I tried it and it surprises me and when it comes to it I give it fuel but under low pressure on the rail.
I was still thinking, for example, on the camshaft position sensor but doubtful.

Ie. is it just how you piss with a poster? Have you looked at what condition your fuel filter is?

Replace the valve on the pump.

Well, it goes only on the cake, the fuel filter is of course new.

You regenerated the pump, you could buy a stimulant (price around PLN 150 with valve PLN 250-300). I would bet the valve behind the pump or on the injection rail.

What fuel pressure can be seen during start-up?

I just didn't pay to buy stimulants, I probably paid for the pump 150 (because it was ok so I only paid for sealing). (I have good access here so I'm not playing with it anymore)
As for the valve is also new and besides I have 5 of them on each and the same subject and the same with the pressure sensor. besides, he should build pressure and throw the rope with the dropped pipe at the injection but he doesn't.

Pressure during start-up 0bar.


Here the problem is rather some electrical because you can not delete these errors for a moment. They don't pop during filming, they are non-stop so it can't be mechanical failure.

Stupid question: how do you remove the connector from the filter and pump the pear this fuel flies?

Yes
The filter is inserted plain metal from golf 2 and has a vent from the top so here is everything pikobelo

There sits EDC15. There are no miracles.
The pressure valve and pressure sensor have no common points apart from the internal connections driver. Either you do not have one of the three masses (although I think they are connected in the middle anyway) or you have some common mass point ext. driver.
the pressure sensor has a 5 Volt power supply from the controller. The pressure regulator has a 12v supply straight from the relay

All the masses are and the computer is different and again the same
