Defender 2.5na not starting

Kevin Weldon · Jun 23, 2016

Hi, I have owned my ex military defender 110 2.5na since February last year. It has been running with no faults since then.
The engine is starting up no problem when cold and when slightly warm, however when the engine has been running for about 5 minutes it won't start up again when turned off.
I changed the glow plugs in December.
Does anyone have any suggestions please?
Cheers
Kev

Won't crank or cranks but won't fire?

If it wont start when warm, it wont be the glow plugs.

Have you checked the operation of the stop solenoid?

Does the starter crank and sound normal when your trying to start it? When you crank it is there any sign of white vapour from the exhaust?

It is cranking and sounds normal but just won't start. There isn't any white vapour from the exhaust.
I haven't checked the stop solenoid, I will have a look and see.
Thanks for the advice, still very much a novice and learning as I go!

Fuel and air filters would probably be worth a check. And lift pump function.
I would look at the stop switch first, though.

Must be the solenoid... surely?

Can you post the outcome when you get to the bottom of what's responsible?
