Disco 1 300tdi EDC 1997 without a Spider Security

Im a little confused here - if the immobiliser is working then it should also cut power to the starter solenoid but you say it cranks over fine? I'd have though if the engine spins OK and doesn't fire, especially since the fobs open the doors then you have another issue entirely causing starting issues.

+1 ... exactly my thoughts after reading the first post though an alarm ECU or engine ECU missbehaviour on the immobiliser path could make all kind of problems

Due to the pump I can’t run a feed from it.

Have spoken to a garage and it needs to go in to be re coded somehow, may even need a new fuel pump, if that’s the case I may as well get away from edc and go manual, I have a think about that one

You can run a feed to the fuel cut off solenoid - its one of the three wires in a three wire bundle connection to the FIP - from memory it's a white wire with a black tracer - (or black with white tracer)

I'm assuming that by "fuel pump" you mean fuel injection pump - loads on ebay for not much money - new one will be rather more.... I wouldn't go away from EDC unless you have to - I had to due the failure of the sensor coil in #4 injector, which was, at the time only available for about £1K .... - if you do go full mechanical pump you'll probably want to make up for the loss in power whilst you're at it with a full width intercooler and a tune up and telling your insurance company.. ( which is what I did ) - you'll also need to change the injectors too - EDC ones are higher pressure.

IMHO You need some proper diagnostics on this vehicle to find out what is going on - and by proper I mean LR specific.

Yeah thats the next step to have a specialist look at it, as I have gone as far as I can.

Could not find any wires coming off the fuel cut off solenoid, only small wire i can see if coming off the fuel injector pump amongst the four pipes.

I would rather keep the EDC to if it possible, I know what you mean by that number 4 injector, i was lucky to find one from a breakers up at the peterborough for about £80 at the LRO show.

have a nosy on the LZIR map for a member on here with diagnostics....

If you were closer I could plug mine in , but given you're about 239 miles away ..... it doesn't really count as "close"

I dont think that the diagnostic tool is the problem as the OP seems to have a Lynx though

Oops - I'd forgotten that sorry. Just re-read the first post ....

So, if we go back to supplying the FIP solenoid with power... (?) I'll edit and upload a photo showing you the wires in question.....

Or not..

well, I just tried to upload a photo of an EDC FIP to show you where the wires are you need to make live... and the flash plugin has crashed ( again ) despite being the latest version. b@ll@cks. If this would help, PM me an email address and I'll send it that way ....

It might be a problem with these fitted with EDC cos i think the immobiliser locks out the engine management too not just the FIP feed, at least that's what's stated in the description of the EDC immobiliser

Seems my #4 injector almost did me a favour then

Bit of an update -

With a new battery finally fitted along with some sort of play around with some of the settings within the ECU, no idea what or which ones, but the end result is that Casper the Discovery has started yay.

Along as he remains good there will be an MOT test later this week, so fingers crossed on that to.

Is your car by any chance a Japanese reimport?
When I had mine I came across somewhere that the " spider" was not fitted and neither was an immobiliser.
This is from memory. I had to get an immobiliser fitted to satisfy insurance co.
I could be wrong but worth maybe looking into.

I wish it was a Japanese import as it have far less rust lol.

The models that have the edc, which are basically the late automatics 300tdis, not sure about auto v8s, didn’t have th spider units I am led to believe.

Discovery is now fully sorted, they had to reset some coding in the edc or ecm, and that along with the plunger in the stop solenoid removed got the landy started. Weirdly it switches off also without the plunger.

And it also sailed through its mot with just a side light bulb issue.

Result

Hey there, sorry to bother you, just read your thread and was intrigued. I have exactly the same issue with my 1997 disco 300tdi EDC. Mines a jap import, and I’d been restoring it slowly for the past 10months, it had corrosion issues. I’ve gone to start it and it will crank but won’t fire. Fuel to the injector pump but not to the injectors. I’ve scanned it with launch diagnostics and it came back with the same fault code as you had posted in your thread.
I read your last post about the ecu needing to be recoded? Do you remember what exactly was done and maybe what diagnostic equipment was used? Any help would be great!

Hello,

In the end an independent Land Rover Specialist, used their expensive diagnostic it to reset the system, I don't think it took long at all. I have the Lynx Evo diagnostic unit and the option wasn't even available on that, guessing the other DIY units are the same.

I would find a local specialist and go from there, as I don't thinks its a DIY job.

Sorry not the answer you were hoping for, but I feel it was the only solution.

That’s ok thanks for getting back to me, The launch diagnostic I’m using has some capabilities, I think I’ll play around with if a bit more. It’s weird how it’s just decided to malfunction

It did have a dead battery for a while and need to be jump started all the time, which didnt help at all

Yeah mine seems to drain fairly quick, will be putting a new one in. Does yours crank for long before firing up?

It used to have that fault.

Mine is an automatic with the EDC system. On this version the fourth injector (one closest to the windscreen) has a wire coming from it, and inside this injector there is a sensor, it was this sensor that was faulty and caused the starting issue on mine. Only way to find out if this is the fault is again on diagnostic equipment, as this did show up a fault to.

I have only managed to find this injector second hand, as Land Rover have stopped making them, and they can't be reconditioned unlike the other three.

Of course there could be other issues, but if yours is showing up that security fault and like mine, does not have a spider unit behind the heater controls, i would go along those lines first to get that solved, as with even a new injector it will still not start.

Bit of a long shot, and I doubt it will work but worth a try.

Try holding both buttons down on the key fob for 10 seconds, then see if it starts.

I doubt it will work, but its an easy try, just read that someone tried this and it worked, but don't know if it the same fault as we have had.
