    there is no code!
    It stays "ON" without blinking!
    There is no way to jump a PR3 ecu that i know of.

    It started to kill my injectors too, i forgot to mention that. Yes i changed resistor boxes, twice. The accord resistor box. I checked the civic resistor box, but both have the same specs. Don't know if that'll make a diffrence.
    :( Help!

    read the article on pulling codes.
    it will tell you how to do it, then do it and give us the code.

    According to the chart bellow, I have an 88-91 ecu. The PR3 came out from the integras of that generation.
    I have 2 ecu's, one is the 901 and the other is a J00

    88-91 ecus (PM6, PR4, PW0, PR3, PM7):
    5spd = 000, 001, 002, A00, A01, A10, J00, J001, C01, C00
    Auto = J51, J50, A50, A51, 901, A60, C50, C51, X30, A80

    As i stated before, the only code on the ecu's window is a steady RED LED, NO BLINKS AT ALL!

    I checked your article sections and this is what it says:
    ---Quote---
    For 88-91 Honda's and 86-93 Acura's:

    The ECU's on these cars actually have a neat little window right on the computer case. No need to jump here- just turn it to on, and watch it right there through that window.

    i'll tell you what... i am not far from it... i HATE electrical problems... i'd rather have a blown fucking engine because all you have to do is replace it but nooooo... not with electrical problems... you'll never figure out electrical problems. FUCK! i feel like seeing how fast my car can go and driving into a fucking 3-foot thick titanium wall.

    >>>Update>>>
    I turned on the car today and all 4 cylinders are firing up. Looks like the injectors are NOT burning up! Something must disable them one by one.

    This shit must be realy bad if the ecu is disabling the injectors at this point. If thats a normal function of the ecu that is.....

    Yes, each injector starts chutting off untill it stays idling on 2 or one injector. Then i'll turn off the motor and it won't want to turn on again till the next day or so. I thought they were frying, but they don't. I guess there's some sort of relay or ecu signal that disables them! i don't know.

    Either way, i think i'll try the following:
    take out every ecu's pin and just keep the vital ones that will keep the engine running. I know it will probably throw a gazilion codes, but it'll be better than a steady "ON" no blink LED! (bad ecu code).

    This could actually get me somewhere i think (not sure).

    These are the sensors i'm thinking about disabling by taking the pins out of the ecu plug.
    A8-VTEC Spool Solenoid Valve
    B3-A/C Clutch Relay
    B5-VTEC Pressure Switch
    B8-AC Switch (ACS)
    B16-Speed Sensor
    B19-Knock Sensor
    C5-Intake Air Temp Sensor
    C7-TPS Sensor
    C8-O2 Sensor
    C9- Oil psi switch
    C10-Brake switch

    I hope it works, or gets me somewhere!
