Bought one of eBay (auto post ltd) as a complete assembly for £220 2weeks back. Don't know the justification on spending more on a relatively simple part ....heavy granted . Good not to listen to rattling marbles in the engine at tick over !

Sounds very similar to my experience with the td5. If injectors and cps are working , you have fuel and are not immobilised it should start. No rpm on nanocom while cranking does not sound right though. I had to crank the engine for prob 30-60 secs while spraying ezzi-start into the inlet...

Ecu definitely at fault - power circuit to injectors was not working. Easy to test with a nanocom when not running but scope required when cranking. True alot of faults can be intermittent but these show as a misfire not a non starter. Concern was after I replaced the ecu and could see...

Me too !! Not good start to ownership when it's broken down after 2 weeks but hey ho. Plus side I'm now familiar with the td5 engine and electrics. Also bought a refurbed ecu from monster tuning with a stage 2 remap. Drives really well now. Eezi start - never had to use it before on...

I did and found the injector circuit faulty hence the refurbished ecu :scratching_chin: All sorted now - took fookin loads of eezistart and lots and lots of cranking just to get the engine spluttering. Once the engine caught it was as good as gold - well apart from the smokescreen that...

Ok - a few weeks on but still have not managed to get the engine to fire. Pulled covers from ECU - no visible damage. Capacitors held a charge ok. Took delivery of a nanocom - checked injectors and found they weren't firing. Verified with scope. Put in refurbished ECU on Saturday - learnt...

No - will take the Ecu into work tomorrow and pop the lid. Pretty sure the RAC guy replaced the 30A fuse to the main relay Friday night. I know he tested the main relay and found it was ok but looked like the contacts had seen some heat at some stage. Replaced both relays to take them out...

Nope - believe that's the difference between our issues. Mine will not fire at all. Replaced fuel filter , whipped out pump. Can't find any problems ?? Sterling immobiliser appears to function correctly i.e drops out power to pin 33 until de-activated. Given up for the day - still leaning...

Yup - but only from word of mouth from seller. Connector plugs to Ecu are clean. Have removed rocker cover, checked timing chain etc. Pulled plugs to injectors Main concern is the engine was running fine but then cut out and since that point in time has not sounded like it will start...

Have plenty of fuel flowing from cooler so don't think it's a fuel delivery issue. From manual fuel flows to regulator and then returns via cooler - unless regulator is 100% faulty can't see why engine won't run unless injectors not opening. Be happy just to get it spluttering at this stage.

Ok - 12V present on pin 33. From what I can see only the Ecu, CPS or fuel pump would stop the engine from firing. Any other suggestions where to look ??

Ok - Got it ! Check pin 33 black connector for power ? Will check this in the morning - fed up with it now. Oh and it's beer o'clock :beer2: Rick

Ok - here goes my tale of woe. 99 Defender 90 TD5 - only had it 4 weeks , 2 off which I was on holiday so was not used. Driving fine yesterday until engine cut out approaching a roundabout. Engine restarted immediately and drove ok 20 miles to work. Similar event coming home but this time...

Afternoon all, New member from Stevenage. Bought a 99 Defender TD5 4 weeks ago and had my first major breakdown yesterday. Not good. Will post problem in Defender section and hope someone can advise Rick
