Has anybody had any experience with a citreon picasso 2.0 hdi engine (diesel),having intermittent non start/cutting out fault. Changed the fuel pump in the tank about 2 months ago, run fine.But has now decided to not start /cut out again. Towed home by AA, who couldnot get it going, but left with no low fuel pressure, fault code.Checked out the fuel system appeared to be no fuel from tank to filter(pump not working?) fiddle around with electrics in engine bay,checked out fuel filter,it started ,no problems,no warning lights on.Since it has cut out and restarted intermittently on several occasions.Is there a fuel pump relay fitted ? i suspect the fuel pump is losing its feed. Any help appreciated.
