    i started a new thread caues the last one got long and drawn out,
    but its a 1989 crx si i put a b18 into out of a 1990 integra,
    the plugs wont fire, and the fuel pump wont come on,
    also there are no lights on the dash at all.
    its a new main relay,
    a good computer, (i put it on my 91 teg and it worked fine)
    and a new fuel pumpp.
    i think my underdash wiring harness may be out.
    or something like that.
    cause i have everything wired up right,
    its just like the computer isnt getting the signal to turn on.
    and i cant get whyy,
    any help is appreciatedd.

    that last reply made me sound stupid,
    i have the positive to the battery hooked up to the
    underhood fuse box,
    and then ran to the starter.
    all the fuses are good,
    i stripped my wiring harness back the other day on a ground,
    and the wire inside was coroded.
    i dunno how much of my harness is like this.
    would that be why my computer isnt getting signall?

    do you have the ground that comes out of the engine harness connected at the thermostat housing? - it is the ground for the ECU, the main relay and most of the sensors - it is on the upper right in the picture with ring connector on the end

    Fix the coroded wiring at your ground and see what it does. It should work alot better.

    hmmm sounds like you have a ground off somewhere,,,maybe even check the wiring from the battery to the fusepanel..and from the tumbler(where you put the key in)
