Default No crank and can't unlock shifter

Hi,
My car has sat for about 4 days and now will not start. My brake lights are working and the P is lit up. However when I hit my brakes I do not hear the shifter solenoid releasing my shifter. I removed the star screw, moved my shifter to neutral and still nothing when I turn the key. Everything looks fine as I turn the key except for the start position.
Please let me know what I should be looking for.
Thanks,
Jomo

Here was my solution to get the car started. I used my fob to lock, unlock the car and then simply start my car.

The shift lock solenoid has a left position blue stiped relay located in the following pic

the relay may be intermittently failing

see page 20

But before digging it out there may be easier things to check

Gday Jomo,

I park in a basement garage, along with other vehicles, and sometimes I have the same problem and the solution is exactly as you used, lock and unlock using the remote.
I think the problem must be interference with the car's security module caused by other owners using their remotes on their cars and the lock/unlock resets it.

Cheers,
Jeff.

The gear shift interlock relay is controlled by the body prossesor module which I think should have a communication wire to the security module

The brake switch is 2 switches in 1 assembly

i switch is dedicated to the brake lights at pin 1 through 4 of the switch , page 114 of the 96 wiring guide

the 1st switch is connected to the BPM at pin 1 through 2 of the switch , page 89

Same 1 through 2 for the ABS / TC module on page 92 of the 96 wiring guide

I'm squirreled up , time for a break . Troy football team on the tele
