Alfa 147 115 hp High Pressure Pump 4C Bosh

[pabloescobar]

The machine ? been a year to a stop and the pump doesn't build up pressure.
I disassembled it and it seems ? all affixed to? when I ride with the hand not c'? the pressure of the diesel.

Has anyone ever had these problems

Hello and thanks

when you have removed that checks have you done?also to understand how can you say that ? ok...............that said, if the pump ? ok ? easy that may have blocked the pressure regulator on the rail and not increase the pressure

[legendaryslave]

it begins to measure the low ? you ? locked the pump in the sebatoio

I agree, also I would start with the low-pressure, after checking the correct operation and the right pressure hallway the diesel fuel filter and it was only after I would pass to the control of the high pressure, even though honestly, I would not open the pump before you have made other controls to the system
let us know and let us reason together, maybe we make the spider from the hole

The machine is already on the road, I had a pump on the ground of the 156 and that's okay. The difference between what ? now on and the one that I took away ? when the rpm hand-spraying diesel fuel and the other is not. At this point the open to see if it had the pistons off by as much, and when I realized that everything seemed to be in place for? not having pressure and failing to understand why? this is a problem in the mass. In diagnosis, the pressure rose to 3.6 while that objective was 480 then I went straight on the pump and in fact ? thus, for? I still don't understand the why?.

Hello

at this point the pumps are similar or the same to turn it by hand it should give you a bit of pressure, but in diagniosi the factor of the objective and the real may be due to the sensor or pressure regulator rail...controls everything well and let us know...

When you replaced the pump did you replace the pressure regulator or not?

are the valves inside that remained open where is that ring of iron
