we have a renault scenice 54plate.rac called yest as would not start.technician said he believes it is the fuel injector,can a faulty fuel injector stop your car from starting?
car has been towed to renault today and they are trying to say we have put petrol in a diesel car!!! every reciept we have found for fuel has stated diesel.we have been driving the car all week with no problem then all of a sudden would not start!! would putting the wrong fuel in the car be responsible for the injectors? the car is under warrenty and obviously seeing as weve supposidly put the %26quot;wrong fuel%26quot; it is now not covered for the injectors! i have had a mechanic tell me the injector was faulty not long ago.feel really angry at renault and dont believe for one min it is the fuel.would changing the injector first start the car?
any help with this matter! thanks in advance
Renault scenic. (wrong fuel)?
Because your scenic is a common rail diesel, if one injector fails then the engine will not start. The faulty injector leaks fuel and causes a drop in fuel pressure, so because all the injectors are fed from the same rail a lack of pressure will effect all the cylinders.
A diesel engine will go quite along distance on petrol, and people who use illegal red diesel, will occasionally run their cars on petrol to wash the red dye out of the fuel pipes !
The problem is because petrol has different combustion properties to diesel, it will burn the injector nozzles away or wash the lubrication from the cylinder bores and damage the engine internally.
If the injector is faulty, then replacing it should solve the starting problem.
It is unfortunate but the dealer does have an obligation to inform renault warranty you have run the car on diesel, and this will invalidate the warranty on the entire injection system. Not all dealers adhere to this requirement as no one ever puts petrol in on purpose, its just a fact that accidents happen.
The are some dealer that would lie just to make some money out of you. So the best thing to do is get the fuel tested.
Renault scenic. (wrong fuel)?
its very common for garages to claim that customers have put petrol in Diesel vehicels.
if the injectors are faulty, clogged or damaged then its quite likely they could stop the engine working. the injectors atomise the fuel so it will ignite. if there is a fault on that subsyetem then the engine will not work. it could be there is insufficent pressure in the fuel system or the injectors are damaged. damage may be that the injector nozzles are too big it may not atomize the fuel adequately.
however it would be difficult to prove that you had put petrol in the tank, get the garage to prove their assertion
however one thing that could be casuing problems is the change in compostion of Diesel (and petrol for that matter), the increase use of biodiesel and ethanol can cause problems with fuel injector systems.
but thats going to be a toughie to prove, and if it is porves is that the cr makers fault or the fuel makers fault, or the polticiains who imposed the changes in the first place.
If you had one injector not working the car would still fire on 3, but it would run rough. If you have all the receipt's saying you have put the right fuel in it then you could ask the RAC to help. I know with the AA if you have problems with a garage their legal department will help out. You could try trading standards.
Good luck
contact rac customer care and explain the situation they will contact the patrol and ask if the fuel was checked and if he believes it was wrongly fueled also ask the dealer too have a sample of the fuel taken from the car too prove its contaminated fuel and phone renault uk too have a warrenty engineer too inspect the car and fuel if you have a warrenty did you recently purchase the car then it may have been wrongly fuelled by previous owner or by the dealer who sold it to you have seen many salesmen put 拢5 of petrol in by mistake
If you have %26quot;common rail injection%26quot; then one faulty injector WILL cause a breakdown.
