Hi all I have a land rover 90 with 1uzfe in it and the auto box. Due to the design of the vehicle there is nowhere to relocate remote oil filter other than back of wheel arch in engine bay near the heater box. I don't drive it that regularly and I think I have drain back issues as it takes a...

Thanks for the replies my donor car was 1997 ls400 european/uk spec change over year the situation is:- replaced all ecu capacitors as at least one out of spec and re lacquered board. cleaned the non serviceable IACV and this has improved. replaced ecu coolant sensor earthed red wire...

Hi I have USA wiring diagrams which allegedly the ecu is correct, the downfall is that we have checked untouched wiring and the colour and ecu pin locations are wrong. I have looked at IACV wiring diagram and plan to test with computer safe circuit tester to see if for some reason the ecu...

Hi Since fitting fuel pump resistor the efi relay behaves. the problem I have is all versions of the wiring diagrams I have been able to obtain do not match a 1998 registered lexus which is the 1997 square headlight model- please point me to the correct diagram Secondly can anyone tell me if...

updated profile okay so my issue with idle appears that the IACV works flawlessly or it doesn't seem to operate- I think it is electrical not mechanical issue. I have sealed type valve and have carb cleaned it. it's frustrating as it starts on throttle but doesn't idle and then other...

Hi I have my 1uzfe running in my conversion, it is de cat and the mil light operates correctly and goes out correctly I have had problems as my conversion the wiring does not match diagrams I have. Could someone tell me if efi 1 fuse (black with yellow tracer) should be ignition fed or...

Could anyone tell us if helicoil will require oil pump removal or if swarf will fall into sump and can be drained out with sump oil thanks

Cruise ecu pin 16 is labled red, mine green with white tracer cruise toyota 88240-50071 is this the brake pedal switch wire in a different colour or am I missing something?

Could someone tell me if the pin 16 1k is a connector block or a resistor please as I have some cut about wiring and it isn't there thanks and pin 20 to combination meter- is this reqired without dash clocks or is it cruise speed input? if so can it be picked up off engine/auto trans ecu pin...

If yours has pre transponder arm then look at wiring diagrams if it is like mine body ecu wires need snip.

here you go have removed body mpx and have engine running still two wires of interest on mpx body ecu body plug second in from left pin 10 (body ecu) red two dots needs to be earthed for engine to run and appears to earth out efi relay in engine bay.(will find out tomorrow) pin 11 (body...

so is there any watch points on picking another ecu? without needing to rewire plugs as I want to use autobox and cruise. Also do you have a wiring pin out for this ecu- will engine run with out body control ecu as at the moment it will not start with it disconnected- haven't yet traced...

Okay my conclusion is that the violet and red tracer and the yellow and black tracer are data from immobilizer to engine ecu. Using a computer safe logic tester I can se that after engine has started there is an earth coded pulse. Knowing the immobilizer eeprom and watch circuit chip model-...

I'll go and look at it now, by the way the ecu and immobilizer on this one are next to each other

Do you have a diagram for usa model? I do understand that your saying data communication between the immobilizer and engine ecu. (serial,can etc) I know that the immobilizer contains a standard eeprom and timer watch circuit-but can't find the microprocessor data sheet anywhere. My next...
