Ok, thanks for your help. One more step further ahead than I was. I was getting spurious readings with the circuit opening relay so, I rewired it yet again without it. I've run ignition relay output to +b +b1 as suggested (i didnt cut the main wire at the computer, but removed the outer...

Recked my wiring again today and still the same result even with a 12v supply from the ignition switch to 1A. One thing I did notice is that the previous owner of the car when it was on the road has removed the 2 sub o2 sensors and plugged the holes in the exhaust with exhaust filler. The...

The company I use have both water and laser machines so I will find out about that, cheers Elliot

I will email the CAD drawings to my laser cutters tomorrow (monday) and will get him to provide some price quotes in both staino and mild Elliot

tried that, but still nothing at 12 and 13A Elliot

Sorry if this treads on anyones elses toes, I'm sure there are a few others on here in the same game as myself, so I appologise in advance...i've looked throught the most common threads on the subject on the board but not each and every thread as theres hours of info and text on this...

Still no joy. I have +12v at 26B I have a good earth connection from 13 and 26D output at 12A and 13A are only 0.08v with ignition switched on I also have nothing at 1A I stripped my whole setup and rewired it again from scratch using the original diagram including the circuit opening...

I chose stainless for my own project and had a few extra sump plates made up at the same time. That's why there are a few other stainless ones being made up by other people. Obviously it requires a lot of skill to be able to weld stainless without it shrinking and distorting but if done right...

I'll check that out, cheers Elliot

Hi, I see you decided to try and bolt the larger mounting positions towards the rear of the engine from the outside. On mine, I've passed tubes through the sump itself and they bolt from under the main pan. Who is going to do your welding? Mig or Tig ? If I can offer any advice, I would...

Hi, sorry to keep posting questions on here every step of the way on my project. the reason is that I only get about an hour at a time to work on my engine which is sitting outside on a frame and usually in the dar, wet and cold so my fault finding process is barely working when I need it to...

Excellent stuff cheers svpmx83, just what I was looking for. I managed to get a faxed copy of the diagram direct from Lexus yesterday, but thats far better quality. Nice one, cheers very much. I owe ya a VB or 2.

Thanks for the help, cant find any diagrams for sc400 either and that site wont let me sign up being outside of the US.......doh! Elliot

H E L P !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! None of the links to the ls400 wiring diagrams on this site are working. Anyone know why ? I have also looked at the http://www.lextreme.com/1UZFE_Crown_Diagram.html page and read through it all. What I have is nothing like that at all. None of...

I've tried the links on the main page of this site, but they arent working for some reason. Anyone out there have a wiring diagram for the engine and compuer for a '91 LS400 ?? Elliot

Thanks for that info Peewee, your a star mate Elliot

Success !!! Removed all the spark plugs, used a good battery from my 4wd, and cranked her over but still no pressure. Removed the oil filter and put a finger over the centre pipe to stop the oil from running out and then had the missus hit the starter again.....a few secs later oil came...

Thanks for the replies already... I'm not 100% sure whether the oil pump goes directly to the centre or the outside of the filter housing assembly, so I could even just be pouring oil against the crank, that might explain why it doesnt flow ? I've now fitted the filter on and plumbed a large...
