ASD relay troubleshooting notes:

The auto shut down (ASD) relay gets power from fuse #6 (15 Amp) and fuse #2 (20 Amp) of the Power Distribution Center (PDC).
The PCM activates the ASD relay and the fuel pump relay at the exact same time and thru' the same circuit (PNK wire).
The PCM activates the ASD relay when the ignition switch is in the RUN or START position and the PCM senses engine RPMs (thru' the crank and cam sensors). If either sensor indicates no engine RPMs, the PCM will de-activate the ASD relay.
