    Default 2zj-ge Ecu pinouts and wiring diagram

    Hey guys, i know there is a thread dedicated to wiring diagrams but no help as yet and this is very urgent.

    Engine is in a st141 corona and is near ready to hit the key bar a few wires that need connecting at the ecu like the batt feed, IGN feed and earths.

    Ive found 2jz-ge ones but not for the soarer, this is a 4 plug ecu and i cant find anything anywhere on any forum.

    Someone please help me, track day in 5 days

    Cheers

    1JZ and 2JZ in the soarer run the same plugs into the ecus so possibly the same pinouts on the body plug

    ok from what i a see the ecu doesn't need start signal to run?

    Maybe it just relys on the AT neutral switch?

    Using those ecu pinouts above i've wired the ecu in, only things i powered up was the +b, IGSW and batt terminal


    Anything else that needs it?

    The coil has no ingition and its not firing or anything obviously, im starting to think the ECU pinouts for the1jz are different

    Need help bad thanks

    You should have m-rel going to the relay to supply power to the ecu which comes back through b and b1
    have you supplied 12v to the injectors?
    here is a wiring diagram

    Well ive wired 12v to those terminals (provided that those pin outs posted at the top were right) just didnt use th m-rel pin to trigger it, dont think that will matter.
    I thought the ecu would supply the injectors?

    Do you have pin outs to go with those wirin diagrams so i can work these injectors out?

    Or seeing as the huge rush im in maybe you could be nice enough to tell me lol

    Cheers

    You should have a wire running from the ignition to the injectors and igniter through one of the body plugs on the engine loom possibly a black/orange wire

    Make sure you have 12v at the injectors take off a plug and measure the volts. If you have 12 v take plugs off injectors and make sure they click when you put 12v across them. They may be stuck shut from sitting for some time

    No voltage at the injectors when the ignition is on but they click when i power them up

    Wonder if i missed anything at the ecu... or if i even used the right ecu pin outs lol.

    you'd think if they were wrong i wouldn't have spark though.

    Hmm any ideas guys, help is much appreciated car is ready for track this weekend apart from this littl hickup lol

    Maybe you haven't applied power to the injectors ?

    One pin will have 12V (measure from battery -VE to injector pin), the other pin will go back to the ECU (The ECU earths this pin to turn the injector ON).



    On the same plug that you connected Black-Orange wire to get spark I suspect there will be another wire that goes to the injectors to power them

    Hint: You can use a multimeter in Ohms / Resistance mode to trace back the wire from the injector to the plug it goes to
