I am going to supply you an answer.
In the underhood junction block, you need to verify that the 30amp Ign4 fuse is good.
If no power at the IGN fuse, I'll need to back trace to possible fuse link.
If If 30a fuse is good, your next step is to access your ignition switch. Check for battery voltage at the Red and White wire at the Ignition Switch. Then turn the switch to the run position and check to Brown wire at the switch to see if you have good strong battery voltage.
While at the Ignition Switch, you'll also want to check the Pink Wire while key is in Run position. That pink wire feeds back to the Underhood Junction block for PCM and Injector Power.
The Ignition switch feeds several circuits.
I'm concentrating on what you tell me is dead, and it should lead us to the no start too.
If the brown wire has low or no voltage passing through the Ignition switch, the we need to replace the Ign. Switch electrical and recheck our system.
You may also want to turn the key to the run position and check for 12volts at an Injector harness terminal. and then with a noid light, verify Injector pulse while cranking engine.
The simplest test is to see why the radio isn't powering up.
All signs point to a Ign. Switch Problem.
Make the first checks and let me know.
Have a Great Day
