4aGZE ecu pin voltage

[punkture]

does any one have a chart to which voltage inputs to the ecu should be, e.g.. B+ im getting 5v etc.. thanks

I'm having a little trouble understanding exactly what you need, some extra punctuation would help.

But if you are after a wiring diagram, there are plenty at club4ag.com in the tech section. Looking at the diagram for a while should reveal what wires carry which voltage. Essentially the 4AGZE (and all older ECUs I've run into) uses 12V, 5V (for sensor power) and earth.

Though it sounds like you have some wiring issues (or a very flat battery) if you have 5V at B+. It should be 12V if ignition is on.

hey hen, thanks mate, made my own circuit open relay that you suggested in another post, but cant find 'run' on car haha its all running on 'on' lol. few questions,

*i havent used the toyota fuse box basically, i stole power feed from am2 and that was my fused power to the efi main relay, then that outputted B+ and sent it to the circuit open which switched via the AFM. The starter i made another relay, i HAD spark and engine cranking, but now nothing lol, only thing i tinkered with was putting in a switch to the ignition feed....is this okay to be done? or have i botched it beyond repair lol????

how would you of started it?
