Hello,
I have a 2015 Dacia duster 1.5dci
I got that car as it was not starting.
I’ve changed the fuel bubble and sensor/solenoid on the high pressure fuel pump and it’s still not starting. I’ve changed the high pressure pump with no luck there too. The bubble gets hard when I prime it and I’m getting fuel out the return when cranking. From what I can see I’m getting no fuel out the high pressure line to the injectors/ fuel rail.
Also tried back probing the solenoid to actuate it but the car still won’t start.
Car starts with easy start but as soon as I stop spraying the engine cuts out

Do u mean that the engine cranks but won't start? Or does it start after priming & a few secs later misfire & die?

When u press the primer bulb, do u see air bubbles coming up the clear plastic tubing from the tank? (The return line is black plastic). If u attach a clear plastic tube to the bleeder pipe on the pump, do u see air bubbles coming down this tube also?

Which 'sensor/ solenoid' did u change?
Do u have any scanner/ App that can graph common rail pressure, rail pressure sensor voltage & RPM?
