Discovery won’t start then did

Recommended Posts

Hi everyone looking for a bit of help.

i got my new 1999 t reg discovery last weekend and has been fine but I decided to take it to work to show the lads, jumped in at 5.45 in the morning put the key in let the glow plug light go out and turned she went to fire up then stopped straight away, tried again and just kept turning over. I tried a few times and nothing. I went back in the house to tel my dad came back out and it fired up straight away. Is this anything to be worried about as I’m a little scared of taking it out now.

thanks in advance

I thought when I saw the title it was the old starter motor trouble, but reading the post its not that..... best thing is to start with diesel engine  basics and make sure of your fuel filter (you have checked all the levels I presume?). Also there is a fuel pressure regulator and a fuel cooler that can leak, if the fpr was leaking badly I guess fuel pressure could have caused the issue you had. Both are relatively cheap DIY fixes though quite fiddly and tricky the first time you do them, there are a couple of D2 specialists on here who may read more into your symptoms but my advice would be to check for those leaks first, google is your friend here, http://discovery2.co.uk/ is an excellent site if you are new to D2 ownership, and look out for http://www.thed2boysclub.co.uk/ as well as this excellent forum here.

1999 - TD5?

If so, run the "fuel system purge cycle" as detailed in the manual. Do it 2 or 3 times, then try a start.

If it starts after a purge-cycle, #1 thing to check is the copper injector-seal washers. I treat these as 60,000-mile service-items.

Thanks for the reply. Ok I’ll have a look into it, I have checked all the levels and everything seems to be fine. I haven’t had the problem since Friday so see how it goes 👍

I have this happen a lot in my 03 Disco 2 over the years.  It does exactly what you have said and continues to turn over with no start.  BUT when I take the key out of the ignition and exit the vehicle (locking it) It normally starts first time on retry  (once or twice I had to have a second go at it).  Now why should this happen is the question....... The best answer I have come up with is the Disco brain is not recognising the key as the correct key and it should start and kicks in the immobiliser to prevent theft.  By disengaging the key and presenting it again the Disco brain recognises the key and starts correctly.  

Well that is what I think and unless someone else has a better explanation I am sticking with it

Hi, I don't think it will turn over if it's imobilized.
