Renault 2.5 G9U650 2007 - Engine cuts out #

Posted by Antony Powell on August 17, 2016, 2:48 pm

Year of Manufacture *: 07
Engine Size and Code *: 2.5 GPU650
( Optional ) Scanner Used: Autologic french

Vehicle broken down with a lack of power and cutting out.

Customer removed and replaced injectors and Air mass meter, we coded them in, vehicle and ran fine in workshop but out on the road cut out with same fault as before. and same codes for high rail pressure ( I am working at a distance from the vehicle so no codes).
Customer had issues with sealing injectors and was told by someone else it was the HP pump, After buying one from our favorite crap parts supplier which made it worse, he opted just to fit a complete new engine.

so new engine including injectors ,pump, rail, etc and a new air mass meter all genuine Renault.

It still cuts out with the same fault of high rail pressure.

I am told the return goes straight to the tank and is clear. all wires from ecu have been replaced which only leaves the ecu.

unless i am missing something so any ideas ??

thanks

Tony

what does live data say about fuel pressure?
is the supply from tank good?

have they looked at freeze frame data in eobd before clearing the code?

just another thought Antony
the most plausible common link is the fuel itself if the codes are accurate, could it be contaminated causing the imv to stick?

Will get the fuel tested when i go but it would have to be really crap as the new engine faulted within a few minutes of starting up.

look for leak off at the fuel rail.
It is giving a high pressure code, but I have lots of rail problems

On the G9U the fuel rail has a pressure relief valve to leak back to tank if pressure gets too high.
Under normal operation, if you remove the pipe from the end of the rail and clamp it, there should be no fuel coming from the emd of the rail when you give the engine a rev.
