Vp44 Problem, Error P1630

[dam234]

I have a problem with the VP44 injection pump, PSG5 electronics.
Car Opel Astra G 2.0 DTI

The transistor was burned out.
It was replaced with an IRLR3705Z


After folding, the pump still does not deliver fuel.


Error P1630 occurs.


The voltage on pins 6 and 7 is -> 12V


What could be wrong ?

Maybe the transistor is faulty again . Isolation on the wires to e valve ? The gate of transistor to the capacitor near IC is ringing ?

The transistor's gate is directly soldered to the capacitor.


The pipes from the valve, which often break, have been insulated with a thermocouple

I am looking at this topic, but there is only a transistor and fuel valve contract related to this error P1630
