    Default 4age ke70 will not turn over


    TO REMOVE ADS, PLEASE
    REGISTER OR SIGN IN
    Hey all, I have just put a big port 4age into my ke70, I can't recall myself touching any of the body wiring of the car, I've hooked the starter motor up the same way it was hooked up with the 4k in it,

    I have a seperate loom running all my engine (injectors,coil,dizzy etc) I have no problem with spark and injector pulse etc

    My problem is I can't get my starter motor to crank over,I can hear/feel starter motor relay click, I have constant power at starter motor main terminal and power at solenoid whilst trying to crank

    Here's the engine bay.



    I have Hooked up good earths, engine bay was recently painted, I made sure it has good connection
    (scratched paint off where earth is bolted to body) earth cables go from
    negative battery-engine block
    negative battery-body of engine bay




    I need help identifying the following wires as to what they are for

    #1
    These two hang off near fuse box/wires that come out of front quarter panel

    One is black and red single wire

    Other one is twin pin plug,
    White/green wire & white/red wire



    #2
    Don't remember wire colour for this one but was hanging down near bottom of fuse box, possibly something for alternator ?



    Any help appreciated !

    - Black/orange trace looks like +12V for the coil, but it's on the wrong side of the engine bay for a KE70? From what I've seen, black/orange trace is usually ignition related on Toyotas.
    - White/green trace and white/red trace is probably the idle cut-off solenoid for the original 4K carb.
    - The plug in the second picture looks like the alternator wiring. If it's a big thick white wire and a yellow wire it probably is from the alternator, I think white will be the charge wire, yellow will be charge light wire.

    I'm more unsure than you mate haha,

    I'm 90% pretty sure the last one is alternator wiring

    I just want to know if any of these plugs have anything to do with my starter motor not cranking

    I doubt they would effect the starter motor. Assuming your battery has enough charge, maybe you're starter motor is worn out?
    What you can do is install a relay for the starter to get more power: use the starter signal from the ignition barrel as a trigger for the relay, and run a new wire from your battery to the relay, then from the relay to the starter solenoid.

    All internals of starter have been replaced last week, I tested it out if the car and it works perfect,

    I took a battery from my other car that's almost brand new but still nothing

    Last pic is definitely alternator wire maybe the sence. Not 100% but I think the black with orange trace is stater signal. I remember I had the same issue when I did my conversion had me scratching my head for hours. Testing with a multimeter all was ok but never worked. I ended up running a new wire and it worked fine. That told me the old wire had broken somewhere but checking with the multimeter came across fine. Maybe just run a new wire?

    Orange and black IS NOT starter wire.

    Only the black with white trace is starter circuit.

    Here is a trick you can try:

    Get a large flat head screwdriver and manually bridge the spade terminal on the starter to the 12v cable from the battery to the starter, the starter will turn over, confirming that its operating.
    Once you have confirmed this, then the signal circuit is pretty much all thats left. The starting system is quite basic.

    And you do need a full 12v at the signal wire to turn a car over.

    Sometimes a dirty old starter will act erratically. You can have it cleaned and contacts replaced pretty cheaply.
