    if you have had your ecm out try disconnecting it an reconnecting, some times the little pins don't make a good contact

    update

    I put the new ecm in today. Grounds are good.

    This engine starts right up and runs if I bypass everything and put 12v directly from Battery to the fuel pump.

    Just bought a new key assembly and ignition switch.

    Will install them on Monday and see what happens.

    Thanks for all the input.
