    I think that fact that you are running an OBD 2 in an OBD 1 car has a big part of it! Also you said that the harness has 4 plugs but the car has 3, do you have all the wires connected? and make sure to use the right ECU unless you have the P28 chipped to work right.

    Yea, you need to use a OBD 2 - OBD 1 conversion harness for this to work right. I don't even know how you managed to plug in an OBD1 ECU into the harness. That just doesn't make sense.

    Also, you can just get an OBD2 ECU.

    You can get the conversion harness from hasport

    scrap the obd 2 harness, de-pin the distributor and re pin it for obd 1, get your old obd 1 harness off your old motor and plug it into the b18c, and then plug in your p28

    i think u have to use a obd2 ecu for it to work.
    or maybe you starter is too weak. my cousin had the same problem and it was his starter

    :withstupid:

    You also need an OBDI dizzy for it to work. OBDI dizzy have two plugs, OBDII dizzy has one large plug.

    Just as said earlier, use your old EX wire harness and take off the OBDII wire harness and forget about it.

    Reconnect your OBDI wire harness to the motor and make it look like the way it did before the swap. Then just plug in your new ecu. Thats it!!!

    Now you need to rewire the vtec and knock sensor to the right spot.

    Oh yea! You would have one extra plug on the motor that you would not use, the one coming out of the crank pulley area.

    This should be about it? Correct me if I miss something........ :D
