Rav4 stalling whilst running

[Purps]

Hi all, got a bit of a weird one here, asking on behalf of my dad, his 55 plate Rav4 D4D is stalling whilst running, it starts on the key without an issue, will drive without any issue, then it dies for no apparent reason, flick the ignition and it will start again, but it will not bump start! 

The engine management light is on and has been code read by the RAC but is very unspecific and only says injector fault - dad has been told that this could be a multitude of things! 

 

Any one have any ideas?

When your Battery is not putting out enough power, the alternator has to work harder to keep the engine running.

When the alternator overworks, it stresses the car's engine.

It is the stress on your car's engine that actually causes your car to stall out; so it's a domino effect.

Fault codes related to injectors, injector controllers etc are considered serious enough by the Engine ECU that should they occur whilst running the ECU can put the car in limp mode and in the most extreme case cut the engine this is designed to prevent engine damage.

What was the faut code?

[Purps]

The car has had a new Battery recently and as for the fault code, I personally dont know. My dad is unsure as to where to start looking for the fault issue

Looking at the fuel supply should be a good path to take, especially with a fault mentioning injectors.

Has the fuel filter been changed recently? How recently? What kind of fuel has the car been getting, good brand or supermarket stuff? Has the car been unused for a while so there's possible fuel contamination? Any unusual sounds coming from the engine? No starting issues whatsoever?

Also the precise fault code could really help.

Has had a brand new diesel filter within the last two months, was completely flushed out with fresh fuel. 

Is used daily and has been since it was brought years ago.

Sorry, but that is wrong.  The alternator is capable of supplying all the car's electrical load, and, simultaneously, replacing the charge in the Battery which was used when starting.  Even if the alternator is developing its full rated current, it will not cause the engine to stall.

Reading fault codes should always be the first step. Any garage will do this for you, but it’s often cheaper to buy a code reader. This will also clear stored codes and extinguish the engine light. A perfectly adequate reader can be bought for around  £10 - there’s loads on eBay.
