RE: Opel Meriva 1.7 CDTI 2004
Check the injectors for leakage. Whats with the fuel filter and the prepressure? Do you have the possibility to double check the railpressure? Last step would be to check the high pressure pump. Are there any solenoids or valves on the pump itself?

Sensor broken or short/open circuit. Try to unplug sensor and look again for that value. Measure the voltage on sensor plug. Should be 5v
