Automatic Shutdown no power to fuse port #34 or #35 no power to injectors cam sensor coils. What could be the reason and how to fix?

Hello, the ASD Relay should have power on pins 85 and 30 all the time (hot at all times), which comes from Fuse 4 60Amp in the rear power distribution center, so if you pull the ASD Relay out you should have power on at least two pins with the key Off. Ill post a diagram of the circuit for you, if power is missing at the relay check Fuse 4 in the trunk fuse panel. Thats a large 60Amp fuse, if that's blown there is a short to ground somewhere between the two fuse panels.

Heres the ASD Relay circuit with fuses 34 and 35, along with the feed from Fuse 4 60Amp. If you haven't checked the ASD relay location for power yet, that's where I would start with a test light, if power is missing and Fuse 4 is not blown, we can look at some OEM diagrams for any connectors between the rear fuse box and the front fuse box, There is also this white/red wire they run out and back into the front fuse box right next to fuses 34 and 35, not sure why they do that, the wire looks to come out one connector and go back in on another. Maybe for testing purposes, but engineers are not that nice.
Using a test light for checking with the ASD Relay out would be best, I would even check this circuit with a higher amperage test light to see if the wire can carry any current. But let us know what you find at the relay pins location.
