Discovery stop working after start

[Filip]

Hello
I have a problem with my disco2 v8, year2002
The car start with any problem but after few sec(1-2) the engine shut off, without any error code, I checked relay fuses, change crank sensor but nothing help, Have you some idea what it should be ?
thank you for any response.

Try the basics
1. check fuel supply
2. check spark

My first though was the crank sensor, but you have done that. So, what about the fuel pump?

[Tins]

Oh yeah, welcome. hope you get it sorted. Someone will know.

Hello
I add video from start to here: Discovery 2 start - YouTube (https://www.youtube.com/shorts/m1yhnI1KJXA)

I remove pipeline from fuel pump in car trunk and it work, sparks word as well
We have this car about 8 year but use it only seasonally and not long distances, it drive about 5000 Km/year.

may be after you watch the video someone will have an idea what I should be.
Thanx for your answer.

To get an answer you must tell the history of this fault... it started doing this just like that out of the blue without any preliminary symptoms? the engine stopped while driving then this cut-out started?... or how?... dont expect miracles while you dont give enough details.

Sorry, but that is a bit harsh! The bloke is obviously struggling with English given his location. He is not asking for miracles.

He has shown exactly what is happening, and I am sure if it stopped somewhere on the road he would have said so. It appears to start easily enough, but what is stopping it when the key returns from the start position?

I have no experience with coil pack types of ignitions, or their associated ECU's having only worked on D1's, but the way he has "tested" both the ignition and fuel is not going to point him in the right direction.

So at first sorry for my English but it is not my native language, I m just learning it.
Long story sort. I parked the car in the garage last night, and in the morning, it wouldn't start. No symptoms before, nothing. Car working well. I checked cables if there is soma broke but didn´t find anything broke or without isolation to make short circuit.
The video is not so good. I put key to "0" position, but the engine was turned off.
Like I said before engine start well but after sec died.
May be some control unit in wrong and do this fault. but it is hard to say when diagnostic don´t show some error code.

Yep. If it was an old type I'd instantly think "ballast resistor". Def sounds like the ignition is shutting off, not the fuel. But I don't know them either.

Please confirm that you have plugged in some diagnostic tool and find no faults displayed.

Especially checking the immobilizer.

Hi,

It's a V8, so it needs spark, so it has a coil.

If it would start with the key in the start position then stop with the key in the 'run' position it could be worn contacts in the ignition switch.

The way to check this is to see if the positive wire to (at) the coil has power when the key is turned to the start or run position.

It could be that simple. The switches with copper dimples inside do wear out and it's not only LR vehicles.

Now we have a starting point, IMO it's electrical, as said above the ignition switch can be at fault, if not another suspect would be the interior fusebox which used to suffer from corrosion inside and can cause a huge variety of symptoms, if you replace it make sure the one you buy to be removed from the same modell(facelift or not) disconnect the battery first then after the swap and battery reconnection turn ignition on 2 and let it so 5 minutes before you crank it for the IDM to regain comms with the BCU otherwise the immobiliser might kick in

first of all replace the ignition relay to rule it out(R4 interior fusebox, the big one at the bottom, swap it with the rear window lift relay which is above then see if the rear windows are working normally)

to go further, from 1 to 10 at which level are you when it comes to electrical troubleshooting? can you work based on diagrams?

BTW what kind of diagnostic tool you have?

[Tins]

Not wrong there. I had multiple weirdnesses with mine, the worst ( but definitely not the only ) one being the starter would engage when the key was in position II. I was able to clean it quite well and it's been fine. It's not difficult, but a little awkward.

Had this after car immobilised itself due to a flat battery...Wrong EKA code given from dealer

$1000 and a good locksmith later...he was able to diagnose it almost asap

Hello All, problem solved, it was MAF sensor, there was some short circuit and it makes a trouble.
So may be in future it will help someone solve the same problem as I have.
Thank you all for response.
