Thank y`all for your help! The engine is runnig good finally. The problem was immobiliser. UK cars manufactured post 1993 have it! The moron who took the engine out of my Lexus cut it off. Take care and may the force be with you!
This car ruined my nerves so I gave it up for few months.
Error code for throttle position. I replaced it (used one from supra) but no effect.
I can tell for a try I used ECU with immo and the engine did not start even for 1s. So you`re right immobiliser is not the reason.
Now I asked...
I have big trouble swaping 1UZ-FE.
Engine taken from LS400 GB / UK version.
Recently I found out UK Lexus were equiped with immobiliser.
Anybody got wireing diagram for this kinda car?
(the whole story and link to YT short movie in my thread "1uz starts and dies")
You`re right - when the video was taken the engine was not bolted down.
Now I`ve got poliuretan motormount.
I tried to wire the fuel pump directly to the battery but effect was the same.
It looks like fuel pump works about 2sec after engine stops. It seems power on injectors disapears at some...
I haven`t check coils yet. But it looks like the current on injectors is beeing shut down - the spark is still on when the engine stops.
There is something that cuts off the power on injectors for unknown reason.
I have an osciloscope but no scantool.
I`ve got stuck. We checked out all the sensors and they are good.
Beeing desperate bought another ECU and replaced it. The weird thing is for several minutes the engine was running just fine.
Then we tried several times starting and shuting it down and....we got the same effect as at the...
First of all yesterday I took my car to better electrician. I simply got sick and tired of the previus garage.
Troble code says there is a fuel pump problem so it`s close to what y`all say.
My question is - does every 1uz have cold start injector??
We looked at my (1996year and sold in UK)...
I think AFM is correct because I boght whole Lexus LS400 just to get complete engine. I swaped entire engine with all the aternator stuff, pipes and so on.
Only airfilter box didn`t fit in and got rid of a/c compressor.
The small pipe after AFM is attachet to nothing and can intake air freely...
Hi I`ve got problem with my 1uz-fe after swap.
I put it into nissan 200sx. Now for some reason after start id dies.
Troublecode says : airflowmeter, air temperature, throtle position sensor.
I replayced them and code says the same. I have no idea why.
the engine stops by itself after 2sec 15...
