Basically the ASD relay circuit is fused battery power in and power out. The rest of the relay wiring (control portion) is between the relay and the PCM. So it's either the fuse, the relay itself, the wiring between it and the PCM or the PCM itself.
An underhood wiring diagram for wire colors and where they go and a test light should be the only tools needed to find this.
If the PCM doesn't see a Crank Position Sensor (CKP) signal after a couple of seconds of cranking, it will turn off the ASD power out. This would make for a no-start or start/stall condition.
The only way that I know of resetting the codes without a scan tool is a battery disconnect/reconnect.
