Tutorial de reparare pompa de injectie VP44

You need to look after the injection quantity only. If the sensor from the pump are in the right position you should get around 4.4-4.8 mg/stroke. In case that you have more than 5 mg the pump are advanced and you will get a higher fuel consumption and more smoke behind the car. If l you have less than 4 mg than the pump are retired and you will notice a leak of power especially at low rpm. If you still have the P1345 you need to change the sensor from the pump.

There are two scenarios what I think you can have. 1. The pump remain advance because the piston from the pump are stuck or partially stuck. For that I suggest to make a parameters scan and look for advance. With cold engine it is normal to have the 11.5 mg/stroke because the pump are advanced. With cold engine the pump are advance 16 degrees sometimes. After the engine are warmed up the pump start to retire the advance . Now this is the point where you must give attention. If the injection quantity are 8 mg/stroke that means the pump remained advanced. That mean you will not have that 2.3 degres advance, you will have more than this value.

The 2nd scenario when the sensor are not in the right position. This can happen if the sensor was unmounted from the pump. But even so the 8 mg /stroke injection quantity can not appear.

So I think more ore less you have the first scenario.

As a suggestions check the wire isolation from the pump unit to the valve what are in the bottom of the pump. In most of the case the isolation pill down and the wire start to touch each other.

As i mentioned above. The only way it is to look after the injection quantity parameter. If let suppose that the piston from the pump work properly than you need to move little bit the sensor to the engine direction. The diameter differences between the screw and the hole from the sensor it let you to play with this adjustment.

Another important point . If you have changed the voltage regulator very important to have a good heat dissipation. Otherwise in very short time will blow up. Most of the people put above of the old voltage regulator what in my point of view is wrong. So as advice it is better to remove the old component tottaly and to glue the new one directly to the aluminum housing

On the way to hell!
I no longer remembered that it would be so difficult to do this with everything in place.
That flat cable is scary!
