Diesel Just won't start

It's a lot easier to read the EMS code from the ECM then read what the BECM has stored with Nanocom to be honest. Certainly a whole lot easier than taking the manifold off and removing top of pump. Think i'll stick with my method thanks all the same.

you must have fat hands if you can't get the top off without removing the inlet manifold

but agree code reading much easier

I've not read all the posts here, but,

Diesels don't have a engine light that illuminates due to sync or non sync.

Diesels will turn over with no other sign other than not firing up.

Don't start stripping the engine down until you have had the codes resync'd.

That's two of us that think that then.

I don't know how the ECU prevents start. But the sensible way would be not to open the ELAB. So it may not matter whether the quantity servo is active. If the ELAB is down it will never start. That is why i said check it earlier.

I would imagine it stops the feed to the pump, Johnny Obviously had his pump apart and it was handy , know that now no need to srtip the pump as a Stethoscope would hear Any activity in the pump with ignition switch , as I said when I get time I will check feed wires, This is only good to anyone who hasn't got a diagnostic machine quick easy way of identifying the syvc problem.
As there is no light

If it does not open the ELAB engine will never start. Because it stops fuel feed to the distribution plunger cylinder. You do not need to lock every door in your house to stop people walking into it. Just the access doors will do. What is active when in sync is not what you need to know, it's what is NOT active when it's out of sync that needs an answer.

Just a meter across the ELAB would surely tell if the EDC is switching it.

True but How would you decipher if its the elab or power to it?

I explained that earlier, just put a finger on it and get someone to switch the ignition on and off. You should feel it cycling.

With a stethoscope?

Use your imagination, power to ELAB can be detected with an electronic stethoscope, (known to the rest of us as a DVM). If no power, apply a direct 12 volt supply and see if it operates.

Ok data has just answerd my next question As to what if it isn't working is it out if sync or faulty,test with power

Or a multimeter on the terminal and to ground, you should get voltage when ignition is on and none when ignition is off. Does not mean it is working though.

PS a bit late. The pseudo Frog strikes again.

Unbelievable.

Has the head been removed yet? How about replacing the starter motor & H/P pump.

I reaken this range rover will end up at the scrap yard because of a simple procedure & an owner that doesn't listen.

Bit like taking the fuel tank out because the flap release button has failed.
