mitsubishi pajero cut-off during acceleration

[legendaryslave]

hi to all the forum I have a problamatica on a mitsubishi pajero 2.5 turbo diesel year 2003 type 4D56t engine with mechanical pump with control electronic throttle km to the taghigrafo 220.000,

practically during the acceleration came towards the 4000 rpm is a sharp cut-off of fuel and the mototore does not break out until it goes to 1500 rpm and then starts to accelerate and begins again the defect, I've noticed that happens even with accelerated from a stop, the tests that have been carried out: diagnosis compiuterizzata ecu of the engine that found the defect on the absolute pressure can't remember the fault code but replaced a tube broken, the fault in the memory ? the most represented.

I temporarily plugged the egr and had no benefits, with a diagnosis in the active values, I do not lose the signal from the pedal accelletore, I do not lose the signal from the sensor turns, the temperatures of both the air intake that the refrigerant in the standard, the advance of objective and real are perfectly aligned and does not record any fault of course when that happens the defect,

I ruled out the power supply from the tank, causing it to go with a tank, I replaced all 4 injectors taken from a pajero is installed but nothing I'm going to riaccellerare and tac riavviene cutting,

the other thing that I noticed the problem does not happen when the engine is cold and when it warms up it starts to lose style shots nozzle blocked, but escudo the injectors to the evidence cited above, at this point, I think a problem with the fuel pump, but why then does it only when it warms up,

any advice or insight would be welcome thank you for your attention

The problem can be in the car electronic control of the pump

you did give a look at the pompista? it would seem to be a problem of pressure oil to the pump

One other thing is when you did the test, excluding the plant with a tank you've excluded also the diesel filter? why? on those cars it lacks the support filter and is suck in air

It is, minus fuel filter and the fact that these pumps do not review only rotation I speak today with the pompista let's see what she says, I would replace the pump and take a blunder and not ? she

This ? a work from pompista and him you must ensure that the failure depends on the pump, and at this point, satisfied or refunded, and the rest of your work from all the controls that you have done the you have done well!

[giuseppe1374]

the pompista you can? to measure the pressure in the basis of the scheme and so to see if it needs to be replaced

Guys thanks for the tips I'll know

do a check from the pompista and then a review of the safe to the injectors
