What would cause an ECM to tick/click when trying to start the car? on 1994 Ford Taurus

My car will not start but turns over like it wants to start, when you turn the key on (like you are driving it) you will hear a ticking/clicking noise that comes from my ECM (has been replaced TWICE). All fuses have been checked, sensors, and fuel pump relay in the trunk.
