Ta for all the advice :) After running through it all with him speed was of the essence as he was losing money daily due to it not starting at all now. He managed to collect a new starter from Devon4x4 so thats been fitted and we will rebuild the old one and keep as a spare when we have some...

Hi guys - popping in for a friend again :o Popped round to see his 2000 90 TD5 as he was having intermittant non start issues. When it does not start there is just a loud clonk noise from the starter motor so im assuning it having internal issues. Its getting a solid battery voltage to the...

Yea but it seems they need to be a specific length and a quite a coarse thread :( Going to look though the spares bucket this week :)

The wire between the main relay and the inertia switch was the dodgy one (think it is white with a green trace). The plastic had a slight slit in it and there were only two strands left - strange as it had nothing to rub on and was wrapped in conduit sleeving ! Seemed to test ok with a...

I think ive got the problem sorted but need to 100% confirm at the weeend before getting too excited - if I have ill put all the info here for future readers :)

I can make it run with a direct battery supply to the brown/orange wires that supply the ecu, maf, egr, ac and a couple of other things but it cant stay that way as it must be switched by ignition normally. Its deffo not immobiliser - Ratty confirmed that with Nanocom :) It looks like those...

Just seen your post :( Another day another update ! ECU has good earths at the 4 wires on the black plug It also has good wires to the relays under the seat. What it does not have is 12v !. It should have it at pins 3, 22, 27 and 33. We only have it at 33 so spent the rest of the day...

Hnady to know that they are swappable and will display the signs as to wether thats at fault or not :)

So if I could get hold of a Discovery ecu would I have to set anything with a Nanocom just to see if it would power up (not even needed to start) ?

Massive thanks to Ratty and Fanatic for coming out to have a look and it seems the plot thickens ! Immobiliser system seems ok. ECU wont communicate with Nanocom etc but we are suspecting that due to it not powering up. They spotted that there are a few dry solder joints in the ecu on...

PM sent :)

Ta for the info :) I believe ratty had a diagnostic system which would greatly help narrow the issue down its just working out when is best :) Even if I'm running the pump off a separate battery and cranking the engine there is still no hint of wanting to start so I'm guessing that the...

Or would you be so kind as to let me bring this ecu to you and try it on yours to see if it does work or not ?

Sorry for the late reply chap - internets been down :( Thats an awesomely kind offer :) I expect I can arrange for the mrs to be there at any time you need along with the key etc if that would be any good ?

Slim as I work until 5 :( I can prob arrange the mrs to be around though depending on what you are planning !

Im Taunton chap The Defender is stuck a few miles north of me.

Nope :( Thats the green relay I believe ? If so it has 12v waiting to be sent to the pump and the pump pin has contuninty right back to the pump. The two smaller switching wires of that relay go back to the ECU and have contuinity to the plugs (one goes to black plug and one to red). Putting...

Tried giving both the ECU case an earth and the spade connector that is bolted to the botttom of the drivers seat base one. I also have 5 earths at the ECU (darker plug) on the 5 black wires at one end of the plug

Power at the interia switch and bypassing the switch makes no difference. Lift pump works with a direct earth and live. Also kept tracing it all the way back to the plug by the expanson tank and can still run it from there. The traced it to the green relay in the centre console and can run it...

Seems the ECU is not switching earther / lives correctly or its not got any to switch after todays diagnostics !
