300tdi cut out and won’t start

steven walker · Nov 20, 2018

My defender just came to a standstill tonight and wouldn’t re start.it will turn over but not start,engine was warm,plenty of diesel in but it just cut out as I approached a junction and wouldn’t start.
A bit too dark to see anything and pouring down with rain!
I’ve just got it towed into a parking space and had to leave it.
Any ideas as best place to start looking?
Timing belt has only been on a year or so ,fuel filter new last winter.

Can happen to anyone, not just defender owners. I passed a 66 plate Nissan the other night with it's bonnet up getting assistance on the side of the A1

Connect a long length of fuel pipe to the filter intake and put in a Jerry can of fuel st on top of the wing giving a gravity fed fuel supply. If it start like this it is likely to be lift pump.

Did it just suddenly stop or did it splutter/lose power first? Also is it hemorrhaging any of its vital fluids?

Having just had my timing belt snap, I would also not rule that out! But check the more simple things first, like power to the stop solenoid and a decent fuel supply. easy way to confirm it is not the cam belt is to take the rocker cover off and see if the valves are moving as you try to start it.

Thanks for all your help guys.
Yes it just stopped at a junction and wouldn’t re start,no coughing and spluttering,just stopped and ignition lights came on.

I went to it today ,the fuel filter was full of fuel ,tried to start it but wouldn’t start.
I did eventually get it to start buy force starting it spraying aerosol up the air filter intake,it started eventually then ran at idle for 15mins,I turned it off and tried starting again and all was good,it started straight away??
Could my fuel pump be on its way out?

Possible blocked fuel pickup in the tank? - it's worth a look if the lift pump proves OK.

steven walker · Nov 21, 2018

Thanks,I will have a look.
I will have it on my own driveway tommorow hopefully so I can start to investigate further.

steven walker · Nov 21, 2018

I’ve just taken it for a 45minute drive and all was fine
Weird how it just cut out and wouldn’t re start and now it’s fine?

steven walker · Nov 22, 2018

Well I’ve had a good look over everything today and can honestly see nothing at all wrong
I’m very worried though that it could happen again at any time with no warning if it’s fuel pump that’s on its way out.
I’ve ordered a new lift pump as they’re only cheap and I will fit it on as soon as it comes but I don’t think that is where the problem is

johnlad · Nov 22, 2018

Friends 300tdi did the same whilst out laning, turned out to be a combination of lift pump and tank pick up blocked with black crap from the tank.

mick 1986 · Nov 22, 2018

Put a piece of clear tube between the lift pump and injection pump, it doesn’t really matter where it goes, but I put mine on the output of the lift pump I think. That will show if it was air in the fuel. Mine died like that at the start of the year, but it lacked power before it died. It was a pig to restart too.

Rougharse Racing · Nov 22, 2018

I had mine cut out on a couple of occasions, turned out to be a loose connector on the fuel solenoid. Worth checking to see if it's a good tight fit.

What’s best way to clean out fuel line/tank?
After checking everything I can think of and finding no reason why it just cut out on me all I can think of is dirt in fuel? It’s been absolutely fine ever since but I just don’t want to risk it happening again
I’ve put new lift pump on,new fuel filter on but both old ones seemed fine
Want to clean my fuel tank now
