View Full Version : '02 Defender TD5 with a starting/running issue!

Hi All!

Glad to be a new member of the Defender community! I've got a (new to me) '02 Defender 110 TD5. I love driving it, even more after I found the wastegate actuator disconnected after a couple days of driving it - I knew they were slow, but maybe not that slow! Anyway, after a bodgy cut washer to hold that bad boy back on, I've since replaced it with a proper E-Clip and its now acting more like a turbo diesel, rather than just a diesel [bigrolf] pulling like the little steam train that a lightly loaded Defender is! There was a couple of things I did to the little truck over the weekend, which included the fitting of the EGR delete (supplied by the previous owner in a big box of spares), and putting a double cut and shut on a wire to the ECU that was frayed, the CAS with a bit of digging in the manual- only 2 strands left! (see photo below)

I've had one loss of power on the highway that was easily rectified by disconnecting the MAF and then driving home, cleaning the plug/sensor and we're back to normal.

However, today, the same thing happened, loss of power, engine chugging - no big deal I thought, I'll just unplug the MAF and whizz home - not to be the case. The poor Landy wouldn't even keep running - it would turn over, run for a few seconds and then cut out. After a (moderately) frantic call home from the side of the road to my cool and calm Father - he said give anything you've F$%d with recently a wiggle and see what happens. So under the driver seat I go, give my home auto-electrician splice a wiggle and the old girl fired up running a bit rough, and I chugged the last couple of Km's home.

Awesome, we're home - lucky I have a spare car! (like all Defender owners should as I'm quickly learning in the week of ownership so far!)

After a few beers and trolling of the AULRO forums, I've ordered a NANOCOM Evo ($589.31!) to help me diagnose whats going on, but I feel like I need a better way to connect these wires from the CAS. I'll have a go at soldering them together a bit later in the week, but they're a very strange wire in that they seem to be a bundle of strands that run inside a sheath to the ECU with two other wires. I know they're shielded because they're close to the starter motor in the engine bay but still - running strands into a pin in the ECU seems a bit strange - even for Land Rover!

If anyone's come across this/similar problem in their TD5 please send me a message as I'm going crazy here - and I'm pretty sure thats supposed to take at least 3 weeks of Defender ownership!

Would it be worth ordering a new sensor as well - are they difficult to change?

Hi all,

If anyone’s interested, looks like I may have sorted the Defender. The culprit - the connection from the main loom into the injector loom in the head. It was loose as, and turns out it looks like while the plug fits on, it isn’t actually able to “clip”. Possibly a disco injector loom, or maybe just a random manufacturing thing. Anyway I actually pulled the cover off and pressed down on the engine plug and pushed from underneath and it still wouldn’t mate up. So a dab of superglue on the joining clips and it should hold till I can get an injector loom that fits or a pin tool and plug that I can swap in.

I also soldered a new wire into the src crank angle connection and heat shrank it, much better than my previous crimp job.

I also need a new top radiator hose, but that’s another story [wink11]

Anyway, Eliza’s back running like the champ that she is! Besides the clunks from the rear links, worn second gear synchro, and off centre steering. But I’ll get to all that.

I would have thought that connector would have evidence of some oil contamination, but it looks suspiciously squeaky clean..

The injector loom has been replaced at some point, and the ECU loom has a very small amount of oil residue on the wires.
