I got at the system to find that the previous owner had recently replaced both of the relays. I changed the fuel relay anyways, and as I expected, it made no difference; the car still exhibits the anomaly.
So, assuming the other (system) new relay is also most likely good, then it seems the fault is either in the ECU or in the notice that it gets from the crank that the engine is turning.
I wonder if debugging this is made easier by the fact that this problem got much worse--critical, in fact--after I changed out the oxygen sensor. I don't know what that adds to the soup, but that is certainly the case.
