Pump should arrive tomorrow so will take the carpet up and test before unpacking.Quote:

We shall soon see!
I would check as per Sierraferys' advice first. You'll be surprised on LR electrics and how intermittent elec faults occur... you know how rocket and astro scientists talk of multi dimensions and parallel universe theories ... it's primarily due to engineering principles at LR, and that if an easy way has been found to achieve something(mechanical, electrical, etc) LR used those newly discovered methods in a parallel universe and so to us they appear backward/idiotic/moronic/stupid/why!!/etc.Quote:

If I were in your situation, I'd have a battery at hand, some jumper leads and remove plug, and hit it with direct power from your at hand battery. Do this a few times to check for pump intermittency.
You could well be right about the pump being the actual issue .. and for sure one day it will. And you have the pump ordered now.
So if you discover that the pump issue may just be a connection issue, you end up prepared for the day when the pump does eventually fail.
Glow plug problems? On the Sunshine coast? I doubt it. I can't recall seeing the glowplug light on my car and I'm in Melbourne.
A TD5 will quite happily start without glow plugs.Quote:

Haha gold! Just like the position of the oil cartridge [thumbsupbig]Quote:

Could be related. However I have played and checked all the earths I could find and it seems to have restored itself.. for now.
100% will be checking the multi at the pump soon before installing the pump. I will most likely take the pump out and clean all filters in any case whilst I am there.
When you say:
You mean, have a secondary battery (perhaps the wifes car) and have the leads from the negative to the battery to the earth on the pump and then the positive to the power on the pump? Would I need to fuse this at all?Quote:

Cheers mate!
Good to know. They are fairly cheap so I was considering changing to eliminate in any case.Quote:

Great to know, thanks legend.Quote:

Ive just rebuild the engine with new head and I am sure new seals and washers were replaced (OEM) (15,000km ago) but they still could fail. Hence why I don't really think its the injector seals/washers.
Could be the regulator still!
Thanks mate!
Yup, the sure is a light for the glow plugs…Quote:

WP = white/purple trace, that's how the circuits are coded in the diagramsQuote:

as about glow plugs they are more important than it appears, it's good to have them working even if it's not cold in your area and won't affect the starting too much cos they keep the engine cleaner inside, they have a "post heat" operation too after the engine was started to improve the combustion so less carbon deposits in time.
4 out of 5 aint bad. to paraphrase the meatloaf song.Quote:

I am somewhat sure that they heat on shutdown also, as there is a big current draw after switch off.
But my light has never come on, except for the usual start up check. Still there is a big draw when ignition is turned on for a few seconds which seem more than just fuel pump as my battery voltage goes from 12.5-7 down to 11.8 or thereabouts for a few seconds. Hard to tell once engine starts as alternator is putting out 14.5.
