    how sure are you that you connected your ICM up properly.

    I have ****ed this up in the past, its posible.

    check your ICM wiring, if your not sure take a pic and post it up.
    get your hands on another dizzy as a test.

    also with a multi meter you can test the ICM signal from the ECU

    I'll take a pic

    I'm trying to locate another dizzy but having trouble

    with the multi meter which wires should i test?
    I tested blk/yel and wht/blu and came up with 12v

    From left to right the colours are:

    yel/grn, blk/yel, wht/blu and on the side I think is light blue

    that looks like its wired ok.

    the blk/yel is ment to have 12v so thats OK, the yel/grn is the ICM signal from the ECU, it should be pulsing as you crank the engine.
    also check the yel/grn wire for short to gnd, this will blow the ICM

    i know it sounds stupid, but make sure the spark plug leads are in the correct place from the cap to the head. compare your engine to a pic or mates car.
    did you do a compression test before they stopped at all?? coz when i built my engine my brother did a comp test, but didnt take out the 'ign' fuse. The leads earthed out and blew the coil in the dizzy, lucky i had a b18b coil, which i swapped and it worked fine.
    check for water/oil around the spark plugs??
    check your battery earths are solid... and if you moved the dizzy or changed the timing-centralise the dizzy and turn it over.
    Boosted Integra underway!
