Jens Posted May 29, 2017 Share Posted May 29, 2017 (edited) I'm have a bit of trouble with my trusty old Defender TD5 from 2000 The trouble started last week when it suddenly wouldn't start. All I got was no cranking over and rapid ticking from the starter. It have acted like that once before - which turned out to be a bad earth connection on the starter, so that was the first thing I checked. I also checked and cleaned all the other connection while under there. It turned out to be a dead battery instead. Easy fix. Then after I couple of days it wouldn't start again. But this time it cranks over like it should, but now I have no yellow glow plug or engine light when turning the key. The purring from the pump in the back is obviously also gone too. Here is what I have done so far which turned out fine (or at least I think so): Checked and cleaned the earth points underneath and under the seat (ECU) Checked all the relays for corrosion Checked all the fuses for corrosion Checked the ECU for oil (There was a tiny hint of oil, but I doubt thats the sinner) Checked the fuelpump by bypassing the relay It can't be the immobiliser as it doesn't have one. Battery, it's brand new. The temperature gauge moves a bit when I turn the key, but the goes straight back down to blue (C) again. If I remove the 30A Main Relay fuses under the seat and turn the key the temperature gauge goes into red (H) when the key is turned. I must have read everything there is on this topic, but still stuck so I would appreciate any pointers. I have attached a few images of the relays and ECU if thats any help. Thanks Jens Edited May 29, 2017 by Jens Quote Link to comment Share on other sites More sharing options...
gerrymc123 Posted May 30, 2017 Share Posted May 30, 2017 (edited) The main earth is a black rubberized strip from the chassis to the transfer box, check it's making a good contact. In fact for all the time it takes I'd suggest removing it, sand and clean the lugs before reattaching it.

Jens Posted May 31, 2017 Author Share Posted May 31, 2017 Thanks gerry, but I have already cleaned and sanded all the earth point without any luck. Looks like I will have to get it towed to the repair shop and get it looked at. Quote Link to comment Share on other sites More sharing options...
Jens Posted May 31, 2017 Author Share Posted May 31, 2017 Turns out the damn ECU is fried What are the chances of finding a new one? Quote Link to comment Share on other sites More sharing options...
V8 Freak Posted June 1, 2017 Share Posted June 1, 2017 What model type is it? Hopefully still a sticker on it... (Something like NNN000120) Then search ebay etc. for one for sale of same model number. Find a friend with Nanocom or similar and then it can be programmed for key and alarm codes etc. Quote Link to comment Share on other sites More sharing options...
Jens Posted June 6, 2017 Author Share Posted June 6, 2017 Ordered an ECU with a performance chip fitted late last week and got it today! Popped it in and started up right away without any remapping etc. So If you need a new ECU, I highly recommend you check with http://mastaz.co.uk Great service!
