Diesel Disco 3 2005 - crancking but not starting
Hi,
We are trying for few days to solve this case:
2005 Diesel 2.7 Disco 3.
Came on tow, no fuel in line.
Replaced lift pump (as it wasnt tworking) and fuel filter (genuine).
Engine started, car drove ~500KM and went bad again.
Engine started but lasted 2-3 seconds.
then the engine stop starting at all.
We tested for rail pressure while crancking - 3600-4100Kpa.
and we had high rail pressure faults.
So we replaced the high pressure pump.
now the engine not starting at all (did a hard reset),
only getting EGR fault.
1. how can we test the injectors? we use MSV-2 but cant find a test like with TD5.
2. any help with this will be appreciated,
Thx

rough idle - hard start
ok, we got the engine started with carb cleaner.
the idle is very rough and low, and tent to stop the engine.
also, seems like not all injectors are firing.
BUT, we can drive the car and goes OK, we went to 140KMH,
and seems like no power is missing.
(we have EGR faults P140A, P0405, P1335)
what can cause hard start (only start with carb cleaner)?
what can make the idle be low and rough?

how much fuel pumping out the Schrader valve.
sounds as if the in tank pump is not good.was the fuel tank cleaned too

I keep reading this short thread, are the original EGR's still installed, or have they been blanked or replaced. Given the EGR codes, age of car, is this not the place to start?

It does happen Moo and there has been more than one forum member on here that has done just that.
Petrol is terrible as it strips all lubrication normally the provided by diesel. The metal on metal contact in the fuel pump does not do it any favours but the microscopic bits of metal work their way around the high pressure system wrecking everything up to and including the injectors.
The damage takes a while to manifest itself and not all drivers owners own up and they may simply sell the vehicle on before the multiple failures occur.Land Rover - Turning Drivers into Mechanics Since 1948

This sounds very similar to the problems I'm having with mine, poor starting then running really rough, clearly misfiring on at least two cylinders, but then when the revs are up at normal road speed it runs fine, the danger is that if I have to stop for traffic etc, it stalls and is then reluctant to start again.
This also started as a result or running out of fuel, It's now with an Indy near Canterbury having the injectors pulled out for testing.Clive

Age showing: I read it as 'run out of petrol'.

Hi All,
Sorry for late reply, we were busy trying things on the car
- fuel tank is clean, fuel tank pump has been replaced.
- EGR has been blanked 2 days ago (we canceled that today to see if it matter).
- no petrol was used at any time.
- the diesel fuel has been replaced with new one, we flushed the lines and replaced the filter 4 times.
- we replaced the high-pressure pump today (again) to a remanufactured one (from Land-Rover).
now the engine still not starting, at the first few starting attempts we got high pressure readings for the rail, and then the pressure went down to ~300Kpa.
currently we get the following fault codes:
EXHAUST GAS RECIRCULATION SENSOR C - CIRCUIT LOW -:P140A -:P140A
EXHAUST GAS RECIRCULATION SENSOR A - CIRCUIT LOW -:P0405
ENGINE OIL TEMPERATURE SENSOR CIRCUIT INTERMITTENT -:P0199
FUEL PRESSURE REGULATOR EXCESSIVE VARIATION -:P120F
is it possible the ECU shutting down the HP pump?
any other help is needed

Could the Oil Temperature sensor be faulty and telling the ECU that it is too hot when its not, shutting down the engine (or not allowing it to start).
EGR codes look normal as now blanked.
Not sure that they have ever caused these symptoms, but are the brake light bulbs all ok.2005, TDV6 S, Auto, 190k miles, owned from new, V8 Brake Upgrade, Nancom Evo, RLD protector, BAS EGR blanking & Remap, separate ATF cooler, changing all the fluids ahead of time.

@dingdongs - can you tell how much fuel pumping out the Schrader valve should we expect?

Not very scientific but when I've bled them it spurts a couple of inches Hope that helps and good luck!

have you tried some easy start up the air intake till the engine fires as it may be air locked and the injectors may not be injecting fuel.bit dangerous to crack the injectors as its high pressure off the rail.Could be a faulty fuel manifold pressure switch but not cheap to replace as -300 is not correct.

@dingdongs - what do you mean?
We strated the engine with a carb-cleaning spary so it will have easy starting.
so there should be no air locked into the system.
also, the rail pressure now is about 1/10 as it should be.
