'Fuel Inject. System' issue

Hi there,
I was on my way to the garage last week with my Range Rover 03 HSE when up on the dashboard came the "Fuel Inject. System" message. It then shuts down and I had to wrestle it onto the hard shoulder. After 5 mins of trying to restart it it eventually started and I carried on for another 30 mins before the same thing happened again. I was going to the garage about something else but when I got there they plugged in the diagnostic machine and there was a problem with an injector. There was also an issue with the fuel pump so to make a long story short all these parts were replaced and after getting back for 3 days I had the same thing happen to me today. Has anyone had this happen to them before and if so what was the problem. I had just under half a tank of diesel. Its a bad problem because if it were to happen when travelling down a fast lane I could be in major trouble trying to pull in somewhere safe while free wheeling and a dead engine under me. All ideas greatly appreciated.

Thanks

What was the Diagnostic Fault code/message logged would help...???

Some have issues with the turbo hoses coming off....but that doesn't usualy end up in a dead engine, just one with no power...

Injectors ??

Sorry but I don't have the diagnostic code. When I brought it to the garage he plugged it in and he was able see the injectors telemetry on the screen and I could see that the second one was problematic. He was pressing on the accelerator and injector 2's figues weren't changing like the other ones. They replaced that and the fuel pump and told me when they ran it again the faults were gone. I wasn't expecting to see that message appear on my dash display again but back it came today. On a seperate note do ye think its worthwhile me getting my own diagnostic unit and if so which kind and any idea how much they'd cost.

RSW all comms is good.

or hawkeye.

but faultmate MSV is the best if your really into DIY'ing for the L322

it does everything a garage's expensive diagnostics machine will do.

Fuel pump or pressure sensor on the common rail would be my first checks.

So to get this straight

They plugged a computer into your car

Out came 2 fault codes :- an injector and a fuel pump

So they replaced them and fault is still there ?

Did they not investigate that the computer may be reading a symptom and not the cause !

A dangerous game to play is to replace (expensive) components simply because a fault code says so (please note MOST fault codes guide the user to "potential" causes and not always the ACTUAL cause)

Personally I would have removed the "potentialy" faulty injector and moved it to another cylinder and then rechecked with the computer to see if the fault code now "moves cylinder".

Must be great to spend a customers money on the say so of a computer and then the fault is still there - I bet they havnt offered you a full refund on the work carried out that HASNT cured your problem

Good Luck and spend further money wisely

That's how most garages make their money

Sad but true

Your profile does not show where in the world you are.Maybe asking for a recommendation to a decent indy close to you would be a good idea.Fault codes are generally accurate as far as they go with Bosch Common rail,but they should only be used as a guide - live data and possibly scope readings should be used to pinpoint the exact area of the fault.They are old enough now that most of the faults are well known.

Hi lads,
Thanks for the replies. The fella who did the work on the car is an independent garage near me who has been recommended here a few times. I have an issue with the Air suspension as well so when I'm getting that fixed I won't be long telling him have another look at the fuel injection issue cos its still there. I'll be looking for him to run some more checks like you have said RS2000CUSTOM. Not the nicest feeling in the world driving along happily then everything cuts out and im free wheeling away with no power steering or engine power especially when I thought I was over that issue.

Hi mate, I've spent hours scouring the net and have the exact symptoms as yourself. I notice your post re the engine cut-out/non-start problem was from December last year. I'm at a loss about where to go from here having replaced the outer fuel pump (not wanting to replace the in-tank one as the symptoms seem different in the case of having to replace that). Please could you let me know if/how you resolved this problem?
I'll be eternally grateful, tearing my hair out with this one...many thanks, Pete

What symptoms are YOU getting??

I have had the same problem with my 2003 TD 6 it's fine around town short journeys. As soon as you go on a longer journey it cuts out. No injector faults. Low pressure faults. Have changed inline pump and fuel filter that didn't change anything fault remained. When it goes you drift to hard shoulder wait ten minutes and restart. You have to drive in left lane as you don't want to risk losing engine in fast lane. I wish it was something just broken then it would be easy to detect. Just changed tank pump over NO GUNGE in tank. Havnt been on long run yet maybe today. Fingers crossed. But if this don't cure it I'm stumped as no rail faults or injector faults shown and don't have any problem starting at beginning of each day

Well went for a 100 mile test drive NO BREAKDOWN maybe it's fixed !!!!

We'll keep our fingers crossed
