Hi Paul. YES. We have changed Single injectors for exactly that problem on Peugeots / Citroens and Renaults, The Rail pressure doesn't even Drop sometimes, but the Valve duty goes high to try and keep the pressure up and it must be when the duty cycle hits a certain limit that the ecu then decides to shut the system down. Sometimes the vehicles will not restart until turned off for quite a few minutes, or until the codes have been cleared. H.T.H. Tony.
