Renault megane 1.5 dci 110cv problem pump 2009

[dvdtuning]

Hi I have a problem with this car, it will not charge the pressure to the starter. Charge approximately 6 bar, pump and injectors have been tested for a tour up to 1650 bar and they are ok. The car in the trailer, but does not hold the minimum.

[frantik3]

check any rel? or me figured out once and was gone a capacitor internal to the ecu

[carlo abarth]

there is a loss of pressure I ricontrollerei the injectors!!

[sno74]

that pump mount this drive....

[munro]

must be a delphi...with ecu siemens..check the pump pressure and low pressure....must give 2.5 to 4 bar...

[blackwolf76]

Trivial question... but ? the type with sensor phase on the pump pulley?? If you do not align, even one not part.

[sno74]

? for this you need to know that the pump mounts to see if it has the pump low diagnosis what you have faults you see pressure on the rail as read in the start-up phase.........

[dvdtuning]

On the pump it says continental k05_04, the ecu is a sid 305...

[dvdtuning]

I repeat, the pump and the injectors were tested on 2 different banks is mounted with the caps and digital pressure gauge...the maximum charge 6-7 bar also from diagnosis! Of course, no diagnosis from nothing!

[blackwolf76]

not ? in a case like this ? the engine that has problems, type-a valve cylinder head that will not close???

Misuragli compression...

[munro]

have you checked that the ecu has all the codes ima injectors??

[dvdtuning]

The compression, however, should be loaded in the pump, the engine runs well and the trailer part no, but keeps the minimum on and off!

[blackwolf76]

and, in fact, the engine may turn off if the compression ? too low... to high speed can increase up to set in motion.

[dvdtuning]

Coding the injectors checked and it's ok...I understand blackwolf but the problem is that the pump is not pressure, it's as if the ecu is not the pilot!

[cinqueturbo]

Fuel filter-fishing vessel?

[dvdtuning]

Has a manual pump for charging the high pressure pump with the clear tubing among other things. You see that tube ? full of diesel but the power and moves very little. Fuel filter new.

[cinqueturbo]

But it was done some work or while it was in gear and the problem was?

[dvdtuning]

While he was running...he has a problem with the butterfly valve must be replaced, but this has nothing to do with the fact that the pump is not loads of diesel fuel.

[cinqueturbo]

While he was running...he has a problem with the butterfly valve must be replaced, but this has nothing to do with the fact that the pump is not loads of diesel fuel.

But with what diag. to analizato?

[munro]

from what you say, it seems that the problem is in the fuel pump high pressure....you do one thing right to take away the doubt if the pump ? ok....trainala put it into motion and thrust with the diagnosis connected check if the press rail match between real values and actual values, especially the minimum....many times on the test bench pumps give more pressure to the one that actually would do normally because the pompisti use a oil test ? much more dense diesel....
if after this test you see that press ? affixed to check the pressure regulator if the regulator and placed checks on the regulator and the ecu send the right signals to the PWM......

[blackwolf76]

I would not like to seem crock, but if the pump pressure should not even when you start to tow...

Maybe ? really the pump load...

[tezzero]

do the test of the 9...feed pump AP with an electric pump at 3 bar..another test would be to plug the pressure regulator so that the pump will not download and see if c'? pressure since ? been tested theoretically it should work...

[dvdtuning]

The test with the plugs and it was made and to tour all is ok but under the car with the plugs does not load the pressure...the test push was made with the diagnosis and the charge pump, the high pressure, but as soon as drops of turns you off! We tried the connectors with a led light and the links are ok!
Diagnosis performed with bosch system!

[cinqueturbo]

To tour the pump to a minimum charge well? and in the parameters?
and tow the car once the game accelerates normally?

[dvdtuning]

A minimum charge 320 bar tour...acceleration is fine, as soon as the spring and drops of turns you off!

[frantik3]

in diagnosis fault you d? including error

[dvdtuning]

Watch unfortunately I don't remember but about the butterfly....now ? out ? waiting for spare parts and then we'll do the other tests!

[dvdtuning]

check any rel? or me figured out once and was gone a capacitor internal to the ecu

I wanted to ask you if you ? success (the capacitor) on the same model ecu why? in this case, I would like to call you to ask you for info on the item if you do not ? a problem.
However, the car is not starting, diagnosis, bosch is not by any error...

[dvdtuning]

Other tests...measured with the oscilloscope valve of the high and low pressure, the high-12v low 11s! Then find the ecu because the signal driving the send...

[igor]

I have to say that I do not know this system in particular, and then I have a question, what regulates the pressure of the fuel from the low side pressure?
usually c'? an overpressure valve, if also here? it might not be the one that remains slightly open and lift the press?
and once set in motion, pushed in or pulled the influx of diesel ? more and then stays in motion, but at the minimum cala and off
I repeat, I do not know this system, and I apologize if I've said it a****ata

[dvdtuning]

Everything is resolved with a diagnosis official renault...it was necessary to make the zero-pressure injectors with the official tester, otherwise the car would never match!
That system is absurd!
