In 4 years of owning my FFRR I have used the glow plugs only once and that was when the temperature dropped to -17°C in Letterfinlay on the banks of Loch Lochy in December 2010

You need,

A spare injector
An empty clear plastic bottle that the injector can sit is flexible high pressure line.

If you take the injector supply pipe off and take it to pirtek or the like they could make one up cheap enough.

Hey. I did this. No liquid emerges from the injector whilst turning over. So either; injector wiring is faulty (Don't think so), a sensor is faulty and or the HP fuel pump has failed? I'm not sure which one to lead towards?

Two warnings are being detected on the handheld;

Boost Pressure Sensor and Low Pressure when starting.

Just checked various fuses etc. all looks good.

So to round up;

- No fuel being sprayed from injector during turnover (Starting)
- High Pressure KPA @ 1000 when turning over.
- Low Pressure KPA @ 320 when priming. - Seems ok.
- Injectors recently reconditioned
- New Fuel Pumps (Rear Wheel) Tank one Seems good. (Car drives fine when started.

Could it be an immobiliser issue?

Don't mean to point out the obvious but the plugs are used when the engine wants they will often run a few minutes after the engine has started they help speed warming up and better combustion and atomisation in the chambers

They can run without them working at all but it impacts cold performance and means it takes that bit longer to feel right. Admittedly being a td6 in such a car you may not feel it that much compared to if the engine was in say a 3series... FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Will, he's talking about the injectors not the glow plugs.

It's not immobiliser. Or glow plugs...

Undo the fuel feed pipe on the fuel rail. There should be a load of diesel come out under cranking.

If there is no diesel, then you are getting closer and closer to the HPFP. If there is loads of diesel, it's probably an injector or 2

I was replying to Johns

Did you test all the injector connectors? Testing just one won't yield a good result if that's the one with faulty connection.

I never honestly checked spray when mine wasn't running right.

If the high pressure pump OR the rail sensor are faulty and not registering or generating high enough pressure then it's logical the injectors wouldn't fire as they couldn't guarantee a proper amount of fuel beig injected.

Does it not run if you Fire some easy start into the intake manifold and start cranking and spray some in whilst cranking? FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

What pressure do you get when running? I've seen from 30k to 130k in pressure readings on mine. FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Hey - Sorry no I did not test all the injectors. Perhaps I should! The rail sensor is reading 1000kpa (turning over). I'm leaning towards the High Pressure Fuel Pump.

Before we removed the injectors - it started on the easy start.

Now no such luck. It will not fire with easy start.

I'm really unsure what more tests I can do!! No leaks anywhere, there is fuel at the rail and at the leak off pipes. Plenty of it. The Injector hardly could be faulty they are just backed from being reconditioned/ tested for the second time (uncle).

The leak off test is a red herring when the injectors aren't firing as they need to bleed all fuel sent to them away as its not being used when it gets above their set pressure.

Test all the injectors.
If they are all the same id replace the rail sensor first then the hpfp FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

Hey Guys.
I checked all the injectors and also changes the crankshaft positing sensor. The car reads the rpm of the engine and therefore I'm left with no choice but to replace the high pressure fuel pump.

I'm lucky because I bought a spare engine from a 530d a few months back and can get all the parts I need from that including the fuel pump. It only cost 290 euro and included everything!

Hopefully this will cure the issue.

Before you go to that extreme swap the tail pressure sensor just incase FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's

I swapped the rail pressure sensor.

No luck.

The time is nigh.

Pump it is! Keep the old one though as they can be easily stripped and refurbished though generally better to just sell it to a refurbishment place FFRR MY06 facelift With TDV8 Alloys Zeros/ATR's
