souynds like a gearbox rebuild needed , the reason it doesnt move is no doubt the front clutch worn out , the problem with the park ? no idea without taking the gearbox out and stripping it ,, sorry i cannot be of any help

You may need to reset the system.

SEQUENCE ACTIVATED BY THE PARKING BRAKE .
1. While engine is running (key in ignition switch), apply the brakes and hold the pedal down.
2. Move gearshift lever to neutral.
3. Apply the parking brake Once Twice
Note: The system can be set - at time of installation - to require that the parking brake be applied once or twice.
If set for two actuations, pause one second between the two.
4. Remove key from ignition (the system keeps the engine running).
5. Exit the vehicle.
6. Within 60 seconds, close all doors.
7. The system will stop the engine and blink the parking brakes once to confirm the sequence is valid (vehicle is
ready for a remote start command).
SEQUENCE ACTIVATED BY THE REMOTE CONTROL

put car in reverse, while rolling set parking break, this will adjust the shoes out, to hold it. Be sure not to set it too many times it will lock wheels down.

Your parking brake is stuck on, try to release the parking brake lever or pull up on the parking brake pedal.

Do you use your emergency brake?

you will need a new e break cable not hard to do but it may frusterate you. a mechanic is recommended as you do need a lince to do breaks.

YEP BRAKE LIGHT SWITCH FUSE IS BLOWED.WHEN ITS BLOWED IT WILL KEEP BRAKE TRANSMISSION SHIFT INTERLOCK SOLENOID FROM WORKING.YOU CANT GET CAR OUT OF PARK.IT NEEDS POWER TO WORK.FUSES BLOWS AT BRAKE SWITCH NO POWER.YOU WILL NOT GET IT OUT OF PARK.SO CHECK FUSE THAT COULD BE YOUR PROBLEM.

The parking brake cable should be replaced but in the short term try getting under the truck and grabbing the cable casing and move them around to get the seized cable inside the cable casing to release keep working the cable until it releases if this doesn't work replace both cables.

do the brake lights work? the system has a lock out that keeps you from moving out of park unless the brake circuit is activated, hence no brake lights no park lock out release, if the brk lights do work u most have a stuck or defective park lock out solenoid.

Either remove the drivers side rear wheel and disconnect linkage or cut the cable from underneath (do this as a last resort... if you want to keep your emergency brake for future use, you'll have to replace the cable.)
