Temporary error, fuel pressure Punto 1.3 Mjet 70CV

You, but it is half the machine check
1. check the pressure regulator that is not locked.... where and how you can? check?
the pressure regulator can safely check with a tester...
2. the pressure sensor gives correct readings..... how to check?
the pressure sensor, you can also check with a tester of the righteous voltages,usa ********for vedereche voltages shall give,or you may want to check with the FES by monitoring the pressure and objective pressure measured..the two values we should not be too much of a difference in max pressure: 100-150bar
3. make sure that the filters are clean and that the power supply and the back are not blocked...... here I could replace the filter and make sure I do not know in any way the pipes
once sostiuito the fuel filter before connecting the piping to return you to blow in with compressed air..I recommend not to overdo it..and remove the tank cap....the eye that if the sebatoio and full and puffs so you could also break it since bochettone supply I know that fit a non-return valve and being of plastic and easy to the full as a reed-pipe..for which eye...blowing "hits" short so that the air that enter at the time of discharge from valvolini vent..
4. verify that there is enough fuel..... well here it is, even with the full.


I had the idea that this error is because? in view of the high demand of diesel fuel in any given situation is that the feed pump is not able to provide input to the pump of the rail that particular pressure. In the corner? words that cannot stand behind the demand of diesel high-pressure pump.
Let's say that if the problem occurred with the original machine this lack of power may be derived exactly from the filter or ducts clogged or just diesel and cold temperatures.

Pu? be cos??the pump low pressure oil flow (0.5 litre-now more than putting out the pump CR..of the series, it seems to me that the car in question rpm to 1350-1400bar with a little press of the rail that you have because you do not need to replace the electric fuel pump low pressure.
I seemed to have read once that on the jtd 105 modifying a valve that was on the diesel fuel filter, putting a higher pressure so that the food is better, the pump of the rail... of course with maps thrusts.
in the 1.3 multijet, you can't vary the pressure and low pressure because the control valve ? integrated in the lid of the fuel filter...

check all, and then let us know...

One thing that I can not understand, in fact, that if I type in the fifth low-speed and I press all the car does not smoke, as if shot 1-2-3-4-5 smokes a lot....
Doing a log with EDF's possible that I have a ratio of air to fuel of 20?

For me it's not ? mechanical problem, but the map! there is something, which you block with the pressure of the gas, try to put ori the pressure and see if you still have problems
