Injection pump for Astra or Vectra DTi...

'Has anyone had experience with the fuel injection pump of a DTi Astra or Vectra? The engine simply cuts out during acceleration, and then it stays off. There are no error codes in the diagnostic system. I disassembled the pump, and I only found normal wear on the pre-injection control valve. The feed pump, piston, etc., all seem to be okay.'
What I suspect now is the fuel injection quantity regulator, which is located at the outlet of the high-pressure side. Does anyone have any reference points, such as resistance values or testing methods, for that?
