laguna dci help ???

[John B]

Hi all I know it's not a Nissan question but my Mrs has a renault laguna 1.9 dci on a 53 plate and won't re start after dying yesterday. As it was cutting out yesterday it sounded as tho it was running on 3 cylinders so my question to you peeps is can I test the injectors by using the 4 thin pipes off the leak offs into 4 plastic pots and just turn the engine over ?? And also if it was a bad injector should it still run but like a dog ?? It's a fuel rail job on these wonderful cars.:thumb2

Had similar problems on a vectra (spit spit).
I checked the ip by loosening each fuel pipe to each injector and cranking it over, and diesel pumped out all of them so the ip was Ok. Turned out to be porous leak off pipes allowing diesel to leak back to the tank and needing loads of cranking every morning to start. I know you don't have the same issue but it would rule out ip problem. It actually needed a tow start to get it to go initially and it ran Ok till it had stood over night.

Thanks mate on this bag of shit I've got a feed coming from the Ip to the fuel rail then 4 feeds off the rail to each of the injectors.

As it died, what colour if any was the smoke.

My T2 was suddenly running like a dog, appeared to be on only 3 cylinders, white stinky smoke, but it still ran.
Put injector cleaner in and it cleared, praise the lord :bow:bow

Have you tried the renault forum? They were really good when I owned a scenic, totally different to this forum but very helpful.
