So turns out its it was a ECU fault, blown earth trace inside ECU, got that repaired and overhaul by anything electronic in nelson, got it back and it starts. How ever no fuel pump relay output from ECU (i earth relay myself to get vehicle to run). Unfortuately it seems to be in some kind of limp mode and won't rev out. Pick up the revs and I it revs pulse up and down, if i plant my foot it sounds like its getting a hard injector cut about 3k rpm. Haven't checked the codes yet, that'll be next.

Engine is a series 1 from the best I can tell, model of ecu is 89661-50102 or 1750004011. MREL is turning on main efi relay control side, as far as i can tell from my wiring diagram which has proven to be accurate so far I have no immobilizer, other than the one that grounds the starter relay, but that isnt wired in.

I have come to the conclusion I have a faulty ECU. This is what I got 12v+ out MREL with ign on 12v+ permanent on B+ 12v+ ign on IGSW 12v- on E01 and E02 12v on one side of all injectors, coil and ign module. Pulse from crank sensor Pulse from both cam sensor I have no ignition module trigger from ecu, no injection pulse from ecu, nothing coming out wire for check engine light, no fuel pump relay '-' output. The way I see it, I have a faulty ECU, weak crank/cam signals or a stupid person looking at it.

What happened to this thread? Looks like some of the useful info I could use is gone. I have a 1UZ that I have wired in, triple checked everything and vehicle wants to go, I got 2 injection triggers out of ECU then stops so engine won't run for more than a second. I suspect this is to do with immobilizer in the loom. Can anyone shed any light on this?
