    2.5 YJ charcoal canister question

    I have the 88 2.5l 4cyl with the same canister and the hole at the bottom has never been tubed up. I believe it's a drainage / airflow hole, nothing more.

    Non starting after new thermostat and heater core flush

    Excellent stuff. I will jump all over this tomorrow morning. I'll check Fuel Pump and B- Latch Relay as well........good thought. Way past midnight now so I'll report back later. Again, thanks for the time and effort in helping me with this. I wouldn't have a clue!!!

    Non starting after new thermostat and heater core flush

    Hi Dorf I pulled and checked the CPS/ CKDS and holy moly, the sensor is only 5 months old and is in pretty good condition, but the hole it goes into was filthy. Took the sensor off and cleaned it up a little, didn't really need it. Then took the rubber surround / door off the crank case and wow...

    Ok, checked all fuses, all are good - (visually anyway :) ) Wow, how do you folks know all this stuff? I am humbled by everyone's help and totally embarrassed at my own lack of YJ know-how!! Right, tomorrow, Sunday, I am going to go through the above very carefully and make notes for every...

    Hi, Ok, A to B switched on gave 11.9 volts. Socket B1 to 2B read 0.20 switched on. A to B cranking gave 9.9v B1 to 2B gave .20v cranking. Is that any help?? Thanks.

    Thanks Dorf. I'll do all that above. Raining here so gotta pause. Does seem to be pointing at the ICM based on my humble tests. Will dig deeper per above and see what what. Cheers.

    Non starting after new thermostat and heater core flush

    Ok, with the key in on notch two but not starting up, I've tested the current coming in on the coil module connector and it's 12v on the A1 pin. Plugged it into the module and tested the positive terminal on the module itself and its 12v. I think that's a good thing? Seems like current is...

    Non starting after new thermostat and heater core flush

    thanks, I try to look after her. It's bloody hard to do in the UK. Extremely limited help and terrible for parts. I'll check everything tomorrow, take some snaps and report back. I managed to test the coil to dist cap and there is no spark at all. Great cranking but zero spark. There is power...

    I'll take some pics of the CPS. I still have the older one somewhere. I'll be getting under the Jeep tomorrow weather permitting. I'll double check it is fitted correctly and connected correctly. I tested the ignition module to the dist cap and there is no spark at all. Could be a busted/...

    Non starting after new thermostat and heater core flush

    Hi all. Tonnes of useful intel to absorb haha! I got a busy weekend coming up testing out all the above. I'll report back with my findings and hopefully get closer to a starting car. Absolutely baffled!! Before and after of the Starter Relay. Just for reference and some engine shots as well. (...

    Non starting after new thermostat and heater core flush

    Ok, here's the deal. Early 1989 2.5l 4cyl TBT LHD here in the UK. I believe she's quite possibly the rarest YJ of her kind in the UK according to people who know about this stuff. That's not a good thing. Not on this island anyway. Other than a back fire issue or two she's never let me down...

    Anyone Downsize Tires For Better Performance?

    I think it's just the 2.5. Never going to be a fast car by any means. It's probably lost some HPs over the years as well. Not much to choose from over here and I probably should've done some more homework when I was buying as it's been a massive problem finding parts and trying to fix or...

    Anyone Downsize Tires For Better Performance?

    Yep it came with these tyres and I have no history of any diff gear changes since 2001 when the UK records began. It was abroad for 13 years before that so it's anyone's guess as to what happened in those days haha.

    Anyone Downsize Tires For Better Performance?

    I literally have no idea what that means to be honest.

    Anyone Downsize Tires For Better Performance?

    Haha, yeah it's come close with byciclrs cutting me off. A few folks have said the same thing. It's just underpowered for such a heavy car. I'll just get used to driving miss daisy then.

    Anyone Downsize Tires For Better Performance?

    I never thought about that. The mass. Of course. Little engine trying to turn those massive tyres, bound to be sluggish and take longer to get up to a decent speed. Good point. I'm stuck then, as to keep it looking like a Jurassic Parker I have to have the KO2s. Shame I can't find smaller tyres...

    Wheel spacing help

    Just seen this thread. Can anyone advise on a good spacer size for my BF KO2s on my 2.5 inch raised machine please? Fiddling with my Jeep whilst it's off the road for the first time in 2 years waiting for parts from the US.

    Anyone Downsize Tires For Better Performance?

    Interesting conversation. I have a 1989 2.5 4cyl on BF KO2s as it's a Jurassic Park Jeep. Are you saying that my sluggish little buddy is because of the tyres and if I dropped down sizes the acceleration, consumption and ride quality might improve. As well as make it a bit faster??

    Left rear brake drum Issue

    Hi, I traced it to a crap, fused rear right brake cable which had been sneakily covered up by a PO. Totally not moving so essentially useless. Despite passing govt MOT months before..... I stripped it, cleaned it, got the cable free inside and refit. It was much better and braked more evenly but...
