P1389:
No ASD Relay output voltage at PCM
You said you checked relays....how did you do that? First thing to do is to go into the PDC, power distribution center, the black box under the hood where the fuses and relays reside. Swap the one marked ASD with another relay. These relays are of the same part number so they can be swapped without issue. If that allows the engine to start, then you know what relay to replace.
Good luck and keep us updated!
