    Had some questions regarding a swap I just completed. First off ....it is a 1992 Honda Prelude originally equipped with a H23A1.

    I looked around and settled on doing a swap of something equal yet clean ......The JDM H23A seemed like a simple choice.

    Converted some of the USDM components such as:

    Distributor
    Fuel Rail
    Ignition Coil
    New Knock Sensor
    IACV
    Oil Pressure Sensor
    Thermostat housings w/sensors
    Compressor Mount
    Power steering pump w/mount


    Everything went together easy and I reinstalled the new H23A . With the new engine I put a slew of new parts on :

    Water Pump
    Timing Belt/Balancer Belt
    Tensioners
    Crankshaft seal, Camshaft seals, Main Seal, Balancer shaft seal
    Timing cover w/seals
    Oil Pan w/Gasket
    Oil filter
    O2 sensor
    Air Intake Sensor
    Ignition Wires
    Spark plugs
    Alternator belt
    Power Steering belt
    Valve Cover seals/gaskets w/PCV valve
    Transmision back-up switch
    Axel seals
    Flywheel
    Clutch w/pressure plate
    Drive Axels
    Main Relay

    After two weeks of building.......The engine will not start. It tries and sputters as if it will, but only dissappoints.

    I have checked most of the common items......It is right on with TDC. Has spark to all cylinders. Gas at the fuel rail. All fuses are good.

    Want some pointers on how to get this going!!!

    Thanks !

    for some reason it doesnt look like your valve cover is grounded. Check that and the starter groundwires.

    do a valve adjustment... also did you check the markings on the flywheel before setting the timing???

    its most likely to be the timing...sounds like something isnt lined up properly. tdc crank,balance shafts lined up correctly,both cams at tdc #1 piston stroke,distributor lined up(rotor pointing to #1 plug) it should fire right up and run smooth,then adjust the distrubutor timing until its in spec. if it sputters and runs like crap ar doesnt start at all,something is retard in the timing(make sure its not a fuel delivery issue 1st),a bad ground, or a bad ecu. hope this helps.
