    Need more info. on your engine like what size! Define terminal 1 or 2. Do you mean no high voltage spark to the plugs?
    Battery voltage (12v) and ignition spark (30kv) are two different things.

    Does the engine start and try to run on two cylinders? If the cap and rotor are not busted and installed
    correctly i think it is impossible for two cylinders not to fire FROM THE DIST. CAP when the other two do fire.
    Especially with all the parts you have installed. How are you checking for fire?
