Just in the last few days, the 2.9 diesel takes ago to fire up. It cranks but doesn't fire. When it does, it runs fine. I've tried googling and it seems various solutions but i did see one about a secondary fuel pump? There's no messages on the dash. I don't want to get stuck anywhere so any ideas?
 
Take the glow plugs out, clean them and make sure they all glow hot in about 7 secs not 25 secs, put them back
Heat the plugs with ignition, turn ignition off and on again heating .....waiting for 5 secs plus after the heater coil light goes out
Spin it over, if not much stop spinning and repeat the sequence so it has 4 x g/plug cycle
If it is plug related it will probably try to start.
Remember often there will be at lest 2 issues to deal with

If its not this then it removes it from investigation before playing with the fuel pumps which is very expensive often
The fact it runs fine once started narrows it down, its often plugs as brianp38dse says
 
Thanks for that, a good place to start. I just have to find out where they are as it'll be the first diesel i've messed with! It did start ok this afternoon and i noticed the 'pre-heating' message on the dash. Thanks
 
I had scoured other forums (only joined this one though) and it seemed that the secondary pump and glow plugs were top of the list but didn't find anyone with a definite answer. Maybe it's a fault with many answers? I'll have to do some more research but looked at glowplugs and they look really buried.
Thanks for the replies.
 
Could be an injector leaking back too much fuel,if the ecu doesn't see a certain pressure in the fuel rail it won't work the injectors to fire up,it may have to turn over faster or longer before it builds the correct pressure up
 
Yes as dove says I put new brushes and re-coned my starter motor plus researched the best cold cranking amps battery that i could afford, fits and has the right terminal layout
 
Battery is spinning things over fine so starter seems good too. Feels more like fuel or, as suggested, glowplugs. A leaky injector, eh? More to troubleshoot!
 
Last two days Rangey has been started and stopped many times and is running fine, go figure! Might start with some injector cleaner. Can't hurt. Thanks for the suggestions so far.
 
Forgot to post any results! Well, it started playing up again after a few days, so took it in to my local independent land rover garage, Sayers in Ashford, Middx. They gave it the once over and found no messages on diagnostics, 3 glow plugs not working as they should but, as discussed, this probably wouldn't be the problem. The pump output was apparently not perfect but above what it requires. They then looked at the injectors and found one was returning a lot more fuel than it should. They recomended changing that, which i gave the go ahead for. I got it back, put some injection cleaner in, filled her up and haven't had a problem since, touch wood.

Three glow plugs not working would be a problem.
