Reply With Quotefuel is leaking out of the flange between the headers and exhaust???? really???
if that is so, then you have an injector stuck open or one cylinder has no spark
4agze problems... SA
picked up myself a ae82 with a 4agze conversion a month back, was going sweet until half way to work one day and it started the sound like a lawn mower. still runs but sounds like running on only 2-3 cylinders and fuel is leaking straight out of the flange between the headers and exhaust.
couple of mates think its injector problem of maybe an ecu problem.
just wanna know if anyone has any ideas as to what the problem could be?

Like said above, check injector O rings could be wedged and injector stuck open which can cause a hydraulic lock in the combustion chamber if that happens say goodbye to your engine.
yep really and it is a fair bit coming out, ill try upload a vid tomorrow. ill see if i can work on it tomorrow and have a look at the injectors.
ok so i took the plugs and injectors out the 2 furthest away from the timing belt where wet, but the injector o-rings on all 4 look to be good...??
it isn't coolant at all?? if it is fuel thats quite dangerous!
how quickly does this happen?
From factory, injectors 3&4 (the ones that are leaking) share a trigger from the ECU. If this wire got shorted to ground (either somewhere in the loom of if the ECU shat itself somehow) then the injectors would stay open and drop lots of fuel into the inlet.
May be a long shot, but is easy to check with a multimeter.
It's definitely fuel, happens as soon and I turn the engine over. Hen I think you might be onto something! Ill have a look at that tonight
i would put a noide light on the injector harness of 3 and 4 and see if it continouly stays lit up or flashesor even test light
Wowsers... Found the Ecu then discovered the messy wiring, wiggled the Ecu plugs around put my injectors back in then started her up and bam! Back running on all 4 runs pretty sweet... Joys of dodgy engine conversions haha thanks for all the help guy much appreciated
