    I have an 85 yota 4x4 with the 22re. My fuel injectors are not firing.

    Ok, here's where I stand at this point.

    The engine will try to fire with starting fluid.

    I have 12v at #10 and #20 on the ecu.

    E01 and E02 showing to be grounded.

    12v from the resistor.

    12v at the injector plug with key on.

    Signal generator in the distributer ohm'ed ok and set gap to .010. (This is reading closed wether the signal rotor in on it or not. Should that be this way?)

    Getting 1.09 v at IGT on the ecu while turning engine over.

    Getting .75v at IGF on the ecu while turning engine over.

    Getting continuity between ground and #10 & 20 on the ECU while turning engine over.

    Getting continuity between injectors and #10 & 20 on the ECU with engine off.

    Have 12v at NE on the ecu with key on.

    I am getting fuel to the rail.

    My wiring harness is grounded to the intake and have checked all grounds all ok.

    Hooked up a niod light the the injector plug, and am getting no signal.

    will this information help anyone figure this out?

    have you measured the ohms at the injector connector?

    should be 13.4-14.2 ohms.



    if it checks out, you need a new distributor.

    i checked your numbers to my numbers, and they look ok.

    except for the ignitor values.

    the signal rotor tells the ignitor what to do, and now its not getting the right info.

    i suggest you get a used distributor from a junk yard.

    It's complicated....
    How long has it been since this thing ran?

    How do you know you have fuel pressure?

    Have you checked spark?

    Have you checked compression?

    Welcome to the board, sorry it's with this kind of problem! :cheers:

    I had my injectors cleaned and balanced by rc engineering, and have recently rebuilt motor. I am getting good spark to my plugs and from the coil. I loosened the cold start injector bolt to check fuel and it seems to be ok.

    When checking the signal generator should I be getting a reading when the signal rotor is not in line. I checked the ohms and it checked ok.

    Crank it over a few times and pull the plugs to see if you have gas on them. If not, it's got to be in the injector system, if there is, you may have the valve timing off and not be getting any compression.

    should I be seeing 12v on both sides of the fuel injector connector with the key on? It seems to me that if on side is 12v and the other a pulsating ground that I should only be getting 12v to one side of the plug. I may be wrong.

    Thanks for the help

    You Also Might Want To Check Your Timing, And Distributor.
