Hello, I have a 2015 Renault / Dacia Duster petrol engine VIN UU1HSDC5E52625544.
The engine cranks but no start. The fuel pump is new but does not run when ignition is turned on. Fuel pump Fuse and relay are fine and when I bridge the relay the pump starts, same when I power up the coil of the relay. Problem is I don't have an output (ground) from the ECU to turn on the relay. It probably doesn't turn on other stuff as even if I manually energise the fuel pump, the engine still does not start.
I cleared codes from all modules but for some reason I can't clear the codes from the engine module, it's called "injection", all codes from it are inactive though.
The only code still active I have is from the instrument panel, it's DF024: CAN COMMUNICATION. SIGNAL MISSING. I haven't found any info on this code.
Oh, I forgot to mention I had tons of codes before on the "injection" module, basically most sensors were showing out of range, shorted to 12V or over voltage. I found a connector with water in it and after cleaning it all faults were gone. What would you check next please? I'm a bit stuck and live in a very remote place called Fatu Hiva in French Polynesia, needless to say there is no dealer anywhere near here nor mechanics other than me. I love your videos by the way! Cheers, Harvey
