bmw 320i e90 my05 not part

[Zac]

hi all ! as the title of this 320i in the morning it wouldn't start..... also has a gas plant...... I have a diagnosis and had only the errors in the climate, but nothing in the engine... I have noticed that when the ignition is switched on does not start the fuel pump, does anyone know if and normal ? or, the pump starts when you press the starter button with the motor ? I ask because the first time I make a 320 petrol and I know that bmw and ... then I saw that it has a double pump because of the separate tank....

Have you tried to get it to start by diagnosing the fuel pump?

[Zac]

yes, I tried,I only hear the relay but the pump does not seem to me starts.... now I don't know if and how the diesel but good or bad, I think you should feel right ?

[Zac]

I tried to give direct current at all, and 2 pumps, but do not start....

[Zac]

From what I understand, the pump, and a control unit.

[macinische90]

if you have a tester test to see if they are in short but seems a little impossible...

[gcmotor]

If you have tried to give the 12v directly to the pump and do not rotate are definitely short.
NB please note that in the tank must always be to gasoline (as the pump always runs at least over the reserve and go often to gasoline, otherwise the pumps fail....if the car has a gas plant.

[Zac]

I tried to make the start-up forced the gas and the car part and it seems to go well,only thing out a bit of smoke,it seems to me from the valvetronic now unmount and do a look at them'.....

[hftdelta]

Sorry zac, but if you have given the current directly to the pumps and do not run,I know that I can go

[Zac]

it's not quite so'..... ? a scheme managed by the control unit with 2 separate motors connected to each other either electronically through pipes...... should be just removed from the tank to try them on as it should...however I found the motor valvetronic burned... now I'll go ahead and vadiamo what else I find....

[maik_93]

I hft...if you went over the ecu by putting 12v to continue to rotate for strength

[Zac]

for now I am dedicating to repair the motor of valvetronic,tomorrow I empty the tank and out all the stuff there ,because I couldn't understand there was too much fuel.....

[manu90]

The fuel pump, it seems to me that is driven in the pwm from the ecu, not from the rel

[rts]

It is similar to the mercedes, which have 2 floats and a pump...smontala and you'll see that ? them the problem

[guaro85]

quoto rts certainly problems to the pump

[Zac]

Replaced pump complete, and repaired the engine valvetronic, everything is resolved
