"We seem to have found a British vehicle that has electrical problems". What are the odds?

[@devin2bievin]

I'm looking forward to the diagnosis. I've been hooked on this XD resurrection since the owner passed it along to you and its cool knowing he's probably following along too. Thanks for bringing us along !

[@patrickfort4467]

Many, many years ago I saw this in a Road and Track on a bumper sticker: Q: Why do the English drink warm beer? A: Because they use Lucas refrigerators. Anyone who's ever owned an English car will get that joke. Your comment about electrical issues brought back this memory.

[@bobholloway7138]

Lucas, Prince of Darkness!

[@1959dud]

Three of my brothers were mechanics I always recall them comment "Lucas. the prince of darkness." 🤣They had a few Triumph 2000's and a Dolimite plus a series 1 jag xjs .

[@bobholloway7138]

@@1959dud Yes, I remember many years ago - around the end of the '70's - when a friend of mine who owned two classic Jags showed me his two checkbooks. He showed me a brown one and said that this was for the cars, then he showed me a blue one and told me that was for everything else. He introduced me to Broken Kitty, the best place to get parts and mods for old Jags. Electronics and conversion kits to replace the straight-6 and the V-12 with a GMC 350 cu.in. crate engine. Most British cars follow the old saying we used to have when we crashed our motorcycles: "You'll heal, the bike takes money." Just substitute "bike" with "British vehicle".

7:47 "We seem to have found a British vehicle that has electrical problems" 😂🤣😂🤣 Good one Steve. That made my day! Keep up the good work. Can't wait to see this one back on the road.

[@thirdcargarage2951]

Side note. Using a brake flare tool. Put a small flare on the end of the fuel hard line. Will keep a hose frame slipping off under pressure. One clamp will do after that.

[@EFTProf]

I knew that from training as a mechanic. made up loads of pipes. Always surprised me why Kevin & Co. keep using rubber tubing..... 😁

[@tiporari]

We seem to have found a British vehicle with electrical problems. Lol! :p

[@paulhall170]

I enjoyed your wry comment about British cars and electrical problems, as an old Triumph owner, I feel your pain! But it will be nice to see this old bus up and running again.

[@mrcogginsgarage7062]

Hello Steve I notice that when you were cranking the engine the oil pressure warning lamp remained alight,this age of discovery as a protective circuit built in that stops the engine running without the required oil pressure if it's been left for a long time it's lost pressure at the oil pump do please prime the pump before you go chasing around all the other systems Good luck with it.

[@Channelscruf]

A permanent rubber hose. Hmm. The British sometimes made interesting engineering decisions. I used to own a Ducati. The Italians also at times subscribed to this approach. It was a fun bike to work on. Thanks Steve.

[@stephenhenion8304]

You just go from one fix to the next!! You gotta love cars!!! Thanks again Steve...

[@poohssmartbrother1146]

Fun fact: if you have the coil pack set up instead of a distributor (sounds like it), it is the same set up as the Series 2 disco. Having as many Land Rovers as you do I assume you have RAVE. I will say, prime the oil pump on these old buick/rover V8's. Cam and Lifters are made of cheese. Check N/P safety switch, oil pressure switch, immobilizer switch, and crank position sensor. Man I missed that start up ding of a D1.

[@robpeabo509]

Go to the start - Powers & grounds from the fuse box to each of the components that are involved with ignition. Then move on from there to the ECU.

[@brwlegge]

If only KZbin had been around in 1974 I might have been able to figure out why my MG Magnette kept losing its spark! Can't wait to watch you figure out why the Discovery won't fire.

[@dexburwell]

Yes. Want to see more on Discovery 1 - I have one…. These are very educational for me 👍🏻

[@bobmanzi7712]

great stuff Steve thanks

[@daveshongkongchinachannel]

Definitely looking forward to seeing this running again.

[@stephenricketts7764]

OK Lucas maybe are not the best but they were one of the main suppliers for years. Some of the problems with our British cars was down to industrial action every other week, mostly in the 70's. Keep going Steve she will run soon.👍👍

[@ThisWeekWithCars]

Believe it or not Lucas still makes electrical components for new cars.

[@earthstick]

Those mice really had a thirst for fuel.

[@robertmorin1454]

Keep the disco vids coming ! Love to see you work through the problems! 🇨🇦👍

[@aikengabrielsen2514]

A no-spark situation is 90% certain the coils. The disco units (and GEMS rr has the same) are a lot easier to do - I put longer bolts in place of the lower mounts on my Thor coils so with the upper bolts removed, I could just slip the coils up and tilt them back. With a head gasket change annually (my engine has the so-called 'porous block' issue), that saves 20-30 minutes each time I need to get the top end off. The way to go is test a couple of cylinders from 1 coil pack and then the other. That's 1 6 5 8 and 2 3 4 7 so if you have bad spark on 4 or 8 of those then that's culprit #1. HT leads fail of course as the factory leads are so-so, but it's rare and you wont see 4 or 8 plugs with no spark, just the odd one or two. At least with the GEMS system, the coil packs are cheap!

[@aikengabrielsen2514]

I assumed before this that you've not got knackered plugs and that tyou have fuel getting to the rail...

[@aikengabrielsen2514]

PS: put some rust converter on the battery tray asap - also on the rear door shuts and the boot tray - as it looks close to unsavable and you do not want to be fixing rotted panels. There are guys stamping replacement sheet parts for discos, but better to stop the original metal getting that far that it needs to be cut out. Welding in replacement sheet is a pain in the bum on them as it's pretty thin and even with a decent TIG welder as blow-through is hard to avoid. Ofc I am an amateur welder so that might be my incompetence...

[@anthonymcandrew529]

Very interesting to watch the careful way you work through teach problem you encounter. I am also looking forward to how this turns out.

[@edjacobs8876]

I had a Hillman Minx. Same exact issue. Simple solution. Traded it for a non running 70 Maverick.

[@richardsims1805]

What? A British car WITHOUT electrical problems exists somewhere.

[@AnthonyMoody]

can't wait for the diagnosis vid (:

[@The9meister]

A common fix for cars like yours, is a tank of fuel, and a lighter, will FIRE up every time.

[@failblazer2004]

nice land rover, currently working on getting a 1994 300tdi disco on the road here in the uk

LUCAS, king of darkness.

[@glennggward081]

Just wish videos were a bit longer. Great content.

[@bobholloway7138]

Hi Steve - good try, at least you solved the fuel issue and that's no small feat! Concerning the ability to start, my experience with XDs is nil, but you touched on the crank sensor and I would check there. All my LRs used traditional distributors, with an attached amp module. The amps they've made for the past decade are very unreliable right out of the box. However, it sounds like the XD's setup does not use this method. Best wishes getting rid of the electrical gremlins!

[@Turbochargedtwelve]

First rule of electrical diag: thou shalt check voltages. Need to find a circuit diagram first to know what you’re looking at. If voltages are OK signals are next.

[@ianrussell9179]

Crank sensor would be my starting point cheap ascwell

[@Kris-jk9mq]

First off: with no FOB the immobilizer is stopping your crank and/or spark/fuel. There is a EMK code u can flip with the drivers door key 1515 or 5151 is the 'Dealer Code' (not sure which, but ie unlock once lock 5 times repeat) and that will get past a LOT of issues. Next check other plug wires for spark, but lets assume their all dead. Check under the engine for Rats chewing wires on back of engine sensors. BUT whatever is stopping the power to the fuel pump is ALSO killing ignition; makes me think immobilizer! Also the Neturel/Park switch can stop cranking as well, might help to wiggle the shifter on no crank, but the hammer trick tells otherwise.. FYI, you probably have to type the 1515 code into the door EACH START! Why I ended up getting used FOBs and paid dealer to program ECU to them. Hope this helps man! 96 disco 1 here

[@ThisWeekWithCars]

The FOB does work and the immobilizer is not the problem.

[@mannye]

Why not throw a little Ospho or some other kind of rust converter at that battery tray? Half an hour with a wire wheel and some rust converter would probably work wonders. Or is that a rabbit hole leading to a full restoration? lol

[@richardguse3410]

Drop everything and get the XD going, PLEASE!

[@ThisWeekWithCars]

If only it were that easy! I did take a look at it last night hoping I could find an easy fix. I didn't...

[@kevinb158]

yeah I would like to see it run it could be anything but if it not running the pump could it be a ignition switch issue or main relay issue or immobilizer issue

[@parkers_projects_]

No genius on land rovers here, but when you were cranking over there was no indication on the tachometer. I know on old 90s fords the Crank Position Sensor can be most easily diagnosed by seeing if you register any rpm on the tachometer during crank

[@born_again_torinos]

Since you asked about videos we'd like to see...I'd love to see some road tests of the Lectra. Go nuts Steve.

[@ToddWinters]

I just had to replace the fuel pump on my 1995 D1. Much easier for me. I had a plastic ring, not metal, so it rotated with just a few taps. Also replaced the fuel filter. My car has no rust, thank heavens, and has a reliable distributor. The only expensive issue I have had is a new alternator. Mine has about 105K miles on it and I have owned it 16 years. Fuel mileage is 10 MPG. :(

[@joesines7583]

Awesome! I love this project. I would love to come by your shop. I'm in your same town. I'm that video dude you met at church that one day. hahaha.

[@ThisWeekWithCars]

Come by any time.

[@thomasbradley4853]

Did you get the XD running brother? I have a 96 that won’t start, and following you here every step of the way. I’m not trying an immobilizer delete I ordered off eBay as I’m not getting spark. Cheers for the great content.

[@acebull7408]

In the next part i think you should also wash it its pretty dirty

[@MrDunky48]

Although Steve asks for help I am never sure he needs it! Seems to have the whole thing ironed out although how he remembers whether he checked for a spark or not is anyones guess. English , American or made in Japan I’m not sure any electrical system is designed to last without attention as long as some of these vehicles. Honest John in the Telegraph used to say about 8 years for most cars and the scrappage scheme we had a while back gave you £2k for a 10 year old car I think. Not sure anyone builds cars to keep out mice either?

[@robt2151]

I rarely buy any car that is less than 8 years old and I usually get at least another ten years use from them (except for my '84 V8 Defender which I have had for 29 years, mouse-free)

[@duncancurtis2926]

@@robt2151And the reason is that you can fix them yourself and I have to pay labour costs! Makes one heck of a difference. And even when fixing them you have found a way to make a few bob out of youtube. None of my skills have earned me even a Pound sterling on youtube yet!

[@DaveJudd]

No spark ,No fuel sounds about right with 90s immobilizes.

[@ryanfitzsimmons8136]

Check cam sensor for broken wire.

[@chrisjones2445]

Judging by your mouse problems. I would put money on the crankshaft position sensor and or the wiring to it. They get melted due to exhaust manifold proximity

[@lambrokedrc5998]

OH BOY! British wiring... Nope, run and hide fer me if it's a positive ground🙉🙈🙊 I guess I could figure it out nowadays... First one was a fiasco... Friends car and he wouldn't believe me till he almost burned the car to the ground🤣🤣🤣 THNX👍💪🍻🦅🦅🦅🦅

Any suggestions on what I do next?

[@alifuatyuvali9912]

@@ThisWeekWithCars You're the expert, I really enjoy watching your videos... Could the crankshaft position sensor cut off spark? I was thinking maybe distributor cap is not clean until you said it's distributorless. Perhaps it's the immobilizer but again would that stop it from sparking?
