Hi. Ran fine. RAC came, tried Easy Start. Ran like a dog on it max 1000rpm, but still turned over fine. Towed home. She is now sounding different then any fl2 I've owned while cranking. Fresh battery. Fuel pressureon crank 480kpa Checked timing crank and cam. It's spot on still. 0 error codes. Just scrapped a fl2 with similar issues, and now this Last edited by Jw2000uk on 29th Apr 2023 6:36 am. Edited 2 times in total | ||

Jw2000uk Member Since: 21 Oct 2020 | Hi nodge. I know 480kpa is nothing. And should be around 20000+kpa I'm running it from a 25 litre drum of fresh fuel. To eliminate the saddle tank. Fuel lines are full. Bleed with my vacuum from the filter leak back nipple. It sounds like it's down on compression on 1 cylinder. Which is unbelievable considering it turned over fine before the easy start. And that was only for a few attempts by the RAC. Last edited by Jw2000uk on 28th Apr 2023 8:18 pm.

Jw2000uk Member Since: 21 Oct 2020 | There's not a single code. 5v and 12v on the rail sensors. Live data records RPM on cranking.. so the crank and cam are talking. Ive just never heard a FL2 turn over like this with a decent battery and even with a one. And it doesn't even attempt to raise fuel pressure thus obviously not allowing the injectors to fire | ||

Nodge68 Member Since: 15 Jul 2020 | It sounds like it's down on compression on 1 cylinder, and as it has a very low fuel pressure. I'm thinking the exhaust cam has broken at the fuel pump drive end. Unfortunately you'll need to take the top off the engine or remove the fuel pump to check for that.Hyundai Ioniq 5 Ultimate. The replacement for the SE. | ||

Jw2000uk Member Since: 21 Oct 2020 | Removed the HP fuel pump to test/replace if needed. And it came out all intact mate. The cam was turning the pump for sure. | ||

Nodge68 Member Since: 15 Jul 2020 | It's definitely down on compression in 1 cylinder. It's strange that a cylinder has low compression and there's no pump pressure. | ||

Jw2000uk Member Since: 21 Oct 2020 | Will check and remove flaps today mate. Possibly down on pressure as the hp pump may have failed? I'll do all the checks, and fit the spare HP pump I've got. When I get to that point Got a oscilloscope coming. To check cam/crank signals. Just need to learn how to use it :/. | ||

Jw2000uk Member Since: 21 Oct 2020 | Just noticed, the compression glow plug adapter is 8mm. Don't have one of those in my kit. Typical. | ||

Cherokee Member Since: 12 Jun 2018 | I have a Halfords advanced 8mm deep socket 1/4" drive socket that a drilled out just for this job. Genuine offer - you are welcome to borrow it & post it back to me when done, just PM me your name & address and I'll pop it in the post if you are interested. Cheers | ||

Jw2000uk Member Since: 21 Oct 2020 | Thank you bud. Would that fit a standard compression gauge? My kit starts at m10. Pm me if OK. | ||

Cherokee Member Since: 12 Jun 2018 | Sorry chap, I may got the wrong end of the stick (not for the first time ) I thought you meant the socket to remove the glow plug, which is a 8mm deep socket that needs to be drilled out to accept the glow plug. I'm afraid I can't help with an adaptor for a compression test gauge. Sorry for the confusion If you need the socket let me know Cheers | ||

PRadd Member Since: 09 Apr 2020 | Wrong end of the stick or not Cherokee.. it's people like you that make this forum great Are you an ex Jeep owner by any chance? My previous was a Grand Cherokee 4.7 V82014 Freelander 2 TD4 Manual Dynamic | ||

Cherokee Member Since: 12 Jun 2018 | Yep I had a Jeep Grand Cherokee 3.2 diesel V reg Agricultural & wallowy compared to LR FL2 but still good fun Best of luck your FL2 issue. Cheers | ||

Jw2000uk Member Since: 21 Oct 2020 | No problem Brian, I did think. How the he'll did he convert a 8mm socket to that lol. UPDATE - inlet and exhaust cam are fine. Chain is fine. Removed Inlet manifold, swirl flaps intact (removed them now) Extra earth added Will wait for a 8mm glowplug compression adapter to test compression. And the amp clamp to test battery crank 1 question - leak off hose, when I suck or blow on the outlet. No air escapes. Is this normal? I've put psi pressure sucking on it. And still it just holds pressure. | ||
