The ECU may not have any power to it. Check the three fuses for it; if they're OK, check the ECU relay.
When you installed the used ECM, did you initialize the keys? If not, the immobilizer system will prevent you from starting the vehicle. If this is the case, the security light will not turn off when you turn the key to "on."
Check the ground connectors. There should be two engine ground connectors at the back of the intake manifold.
