follow your negative battery cable and make sure its grounded to the block, as well make sure your engine harness is grounded propperly on your lower intake manifold.

The STA signal to the ECU affects it but is not solely responsible.

No.... test it. RTFM man. Test/inspect the following: starter STA pin at ECU while the engine is being cranked, igniter, ignition coil, plug wires, spark plugs and AFM... Test them all when the car is acting up and then again when it's warm and starting fine, then compare results.
