Ok, 19 posts and you're still no where. Sorry, i've been away for the last 3 days.

Righto, you should have power at the dizzy (yes distributor, sorry). There are two variations of dizzy's, the most common is the wiring with a Black, White/Red, white and light green. When youre reds are on, you should have 12v on the white/red wire (2nd one in, back to front when looking at the motor).

The blue/red wire at the ECU that you're getting 12v is the constant power, should be position 1A (smaller yellow plug and position 1). This is good that you're getting this. When you turn ign on (reds) you should also have 12v on pin 1B. This is also a white/red wire, will be below the constant 12v wire. If you haven't got this, your no power at dizzy and no power at ecu is related.

Final test for me to know what I'm chasing...pull one of the injector plugs off. Switch to reds and you should have 12v on one of the plug pins. Again it will be the white/red wire in the injector plug if you want to be specific.

Please confirm the above and let me know how you go.

thanks, rob!!

I will test those things today, first have to sell old 4wd box.
I tested that white/red wire yesterday and it connects with earth when ign off.
Is this normal. And the reason was lambda sensor.

Ok, tests have been done.

When ignition is on:
-I get again 12 volts to blue/red wire in ecu.
-I get no power for white/red wire in ecu!!!
-I get 0.03 volts in most left injector, white/red wire.
-I get same 0.03 volts to distributors white/red wire.

But if I unplug lambda sensor I get both injector and distributor 1.83 volts.
This maybe normal if lambda changes as engine heats??

Problem seems to be that white/red wire somehow.
Have to look where it goes.

It started succesfully!!!!!!

Problem was that "fuel inj" relay was not getting any earth!!

Thanks all for help!!!
I will tell more about my project later!

Excellent! That's was my next step to tell you to check.

Glad to hear you sorted it.

Hi would you recommend the place where you got your front cut? I got a price of $1800 delivered to South Aus from the same place, which is the cheapest i have been able to find

Ian · 27-04-2006, 04:24 PM

1800 is very good. Mine cost 2k plus delievery in brisbane, however I was able to inspect the cut and see it running before I baught it.

I bought it from Malaysia.
