Iveco Daily 2005 3.0 HPI E4 - The CR pump does not supply fuel.

Hello! I have a problem with Iveco daily. The car was bought with damaged injectors (started from a cake). Someone was rummaging earlier because two injectors were from 2.3 and two original from 3.0. I removed and took to repair along with the pump cr. Two injectors were purchased completely new. After assembling the whole, it turns out that the pump does not give any fuel at all. After running on the plaque displays error camshaft sensor and after some time sensor error in cr. The electric pump works and pumps fuel up to max 12bar. Everything checked out. I will add that after unscrewing the pressure regulator in the pump and turning the key, no fuel leaks from the place of the regulator (I have no idea if it should or not, the buzzer regulator makes a sound). I have no idea where the problem may be. please help or at least tips.

Hello!
I would check the shaft position sensor. A friend had a sensor that was replaced with a new replacement and the pump did not supply fuel after replacing the original with a propeller (only 2.3 in ducato)
And I have such a question whether in Iveco 2004 2.3 116km electric pump works after turning the key all the time, while the engine is working?
Regards!

The fuel dose regulator in this toilet pump CP3, when it gets voltage (buzzing), it lowers the high pressure when the electrical plug is disconnected from it, the pump gives maximum pressure on the strip. After pulling out the dose regulator, fuel should flow out of the opening under the pressure of the pump in the tank. At 12 atm of power, even after unscrewing the hose on the injector fuel should flow out.

According to what I orientate, the pump in the fuel tank pumps from 4.4-5.8 before the filter and after the 3.5-5 filter
In this injection system, the pressure regulator
placed in front of the high pressure pump, regulates
fuel flow required for the low pressure system.
Then the high pressure pump feeds correctly
fuel rail.
Such a solution, increasing the pressure only necessary
fuel quantity, improves energy efficiency and reduces
fuel overheating in the system. Bleed valve
mounted on the high pressure pump performs the function
pressure maintenance, at the pressure regulator inlet, constant
5 bar, regardless of filter flow capacity
fuel and system behind the filter. Operation of the bleed valve
it increases the fuel flow in the circuit
cooling the high pressure pump.
12 bar is way too much

It is very likely that the reason is simple. If rotation sensor errors occur, check the crankshaft clearance. Use a wheel bucket or rod to push the pulley away from the front of the engine and then to the other side. If the crankshaft moves, it means that the bushes at the rear (thrust) are worn, causing the flywheel to move away from the sensor. In this engine, this sensor is mounted on the right side of the engine receiving impulses from the side of the wheel and not from its circumference. This causes that if a too large gap occurs, a sensor error occurs and the engine does not start. I apologize for my oversight this defect occurs in the older engine model and not in the HPI E4.

With these clearances on the retaining bushes, it seems to me too much. Alternatively, the shaft sensor can be detached (it will ignite without it), but not the other way round. Look through the oil filler cap whether the timing guides do not diverge, a fairly common case when the oil level is low - although then there should be an error, an inconsistent signal from the above sensors or something like that.

Mr. Dawid W, it's difficult to understand what you mean by your speech. What I have described many times was a problem in starting the engine. It is certain that the Iveco Daily car will not ignite without the impulses from the flywheel, but if there are no pulses from the timing wheel then the engine will work unevenly, it may weaken because it will not be possible to determine the correct injection angle. Buddy "MechAM" enter what value in the diagnostics the pressure sensor on the strip at the standstill and when the engine is running shows. If the pressure shows you at a standstill, the high pressure sensor or its wiring may be damaged. This can also be the reason for a difficult start. One more request write if the pressure regulating valve is screwed on two or three screws. Buddy "MechAM" in the attachment is the fuel system for this engine if it is a system on the pump cp3 or fuel control valve screwed on three screws.

I don't quite know what is unclear to you, Mr. Stanisław Piotr, but I will try to explain something.
The car will not fire on only one crankshaft sensor because EDC does not know where it is which piston. It is different if we have a sensor connected to the valve. On the suction roller in a certain place we have "two squares" cut out and the ECU may not be the first time but it will allow the car to start. Not as fast as on two sensors but it will fire, it is due to the fact that the controller can give fuel as the piston will be in the DMP, until it finally "hits" and then it will go according to the map.

And here you are mistaken "The car will not fire on only one crankshaft sensor because EDC does not know where it is which piston." .It is notches or boring on the impulse wheel on the crankshaft that allow the controller to detect the GPZ of the first piston the other is determined by counting pulses from the marker. They divide the circle into many parts in which one field is empty or another point is arranged. And the information on the camshaft pulses (phase sensor) allows you to determine the advance angle. Below, info from the engine in question.
