Main Relay Rapid Clicking

So, still have not gotten my beat up to a running condition as yet. Been through the usual with Igniter, Coil and Dizzy replacement plus i rebuilt the ECU.

Bought a used ECU off of ebay, gives diagnostic codes but won't start the car. The old ecu started the car, but now the main relay clicks rapidly whenever the fuel pump primes and while cranking over.

Anyone have a basic main relay diagram, I am getting several wires giving continuity to the ground and I fear that's the issue plaguing me at the moment.

I should be in here

Thanks Big B. I am not sure what is going on with the car, need to check the main relay harness on battery off, battery on, ignition on and starter on. Thought there might have been a short, but not sure. Ground wires look ok, did not disconnect anything that would have caused this issue.

Turned out to be a defective relay, bought an aftermarket one off of Amazon for now.
