Defender 110 TD5 won't start...

Hello Turboman,

Yes you are right absolute learning curve! This is my first Landy. Had it about 6 months. Know my way around a modest car but as you guy's on here know a Landy doesn't compare with anything they are unique! ..that's why I saved my pennies & finally bought one. I shall never drive anything else now - Love the machine. Your great advice is sinking in and those jobs you speak of will become my maintenance list etc. I'm wondering if its my ECU thats damage by oil or leaving the battery connected whilst I unclipped some of those wire's I mentioned.

Thanks for all the advice mate. I will post what action I'm taking & what my progress is.

Cheers.

Hello Mr Brown,

I'm really grateful to you for such a comprehensive to do list. As I previously said in some of the replies in my original post. I did not disconnect the battery to change the offside brake pipe (which I would normally have done)... then like a fool I disconnected some of the (wires in corrugated plastic tubing) connections directly under the plastic radiator filler tank & fed the wires toward the back of the vehicle to make some room for the new pipe which was getting tangled up on the chassis etc. Fitted everything back together - bleed the brakes & the Landy won't crank/turnover. Got all my dashboard lights, indicators, windscreen wipers etc though.

Have used plenty of contact cleaner on the big red connector but am wondering if I've got a busted ECU???
Also cleaned up the connectors I disassembled. I get paid in a few days time so will clean or replace my glow plugs & replace the injector loom like you said.

The knowledge you boys on here have is incredible. So helpful. Thank you to everyone whose chipped in with advice. I will let you all know how I get on. Will get some AA or green flag cover very soon. Thank god my wheels are outside my house & don't require recovering from some where.

Many thanks

I don't think the ECU minds if you disconnect the odd multiplug whilst the battery is connected. Obviously it's a good idea if extensive electrical work is on the agenda but it can't be that sensitive, or you'd need a new ECU every time a bulb failed or a fuse blew. And that's not (usually) the case.

If it's not turning over at all, then it's worth checking how the electricity is getting to the starter and back again. All the way from battery to starter solenoid and back again via the earths. On mine there is a little wire that goes on a spade terminal on the starter that is apt to make a poor contact once in a while so the starter won't turn. Pulling it off and cleaning it and giving the female part a squeeze with a pair of pliers so it grips the male part is helpful.

I've had two TD5 ECUs effectively 'brick' themselves and become useless, but the starter still spins away merrily, so it's likely to be a starter circuit problem in my experience.
