my disco 53 plate is having trouble starting cold ive noticed that now and then the glow plug light doesnt come on

first of all check for oil in the ECU's red plug and give contact spray to both plugs

Glow plug relay failing?

on a D2 you can remove the relay, the fuse or all the glow plugs and the warning light must come on as it's controlled by the ECU based on temp. sensor's signal

where is the relay and can it be swapped to test it

oooooo I thought the lamp would be on one of the poles of the relay, to signal that its on and working, stupid landrover design??

Yes.

Check the ECU plugs for oil first as Fery says.

i changed the harness and give everything a good clean but if anything its worse today the engine turning over ok but not engine not starting
any other ideas
thanks

Did you open up and clean the ecu out with electric contact cleaner . Or did you just clean out the plug socket on it

clean as a whistle inside what next ?

Wouldn't hurt to have a quick check on the old fuel pump is running as it should and also maybe put a new fuel filter on just to rule them out

the engine when warm starts straight away also how do i check the fuel pump the easy way
thanks

Sorry thought you said it wouldn't start and just turned over after new harness and a clean . Could try next cold start if if don't start 1st time is to then do a purge start up routine from the hand book .

i couldnt start it yesterday it eventually started today later on when starting it wouldnt fire i checked by the filter and the pump was running i dont know if this is right

changed fuel filter and it wont start at all now battery has gone flat - on charge
any help would be nice

After changing fuel filter did you do the purge start up to get any air out of fuel lines . It's in the hand book on how to do it . Plus if your battery's a bit week/old you might be best doing it while hooked up to jump leads . As it take a lot of cold cranking from a battery to get them started! This could be a factor in your poor starting ?
