Engine starts but I can't get it out of park. I can overide brake/transaxle link,but dash display,power locks and head light sensors won't work .

USA answers me, and only.
No FUSE blown, cab/or bay(eng)!?
sure all brakes must work, or shift lock fails.
for sure rear brake lamp
park lockout is covered in the SM/

read how it works.
why workl on any car and not scan it first. see what's failing

the dash has PRND1234 display does this work? right?
if the PCM sees any kinds of TRANNY or brake conflicts the PCM blocks , starting the engine, as in look Ma' not driving over the kids.
brake pedal safety module not failing
the book says use the backup light sw page for setting park switches.

The neutral safety switch is a combination switch that also controls the backup lights and gear position indicators. The switch is located on the transaxle assembly.

the cause may be brake path or the transmission TRS park 'neutral
PRNDL switch failure or not adjusted as the book clues.

spring --damaged clip--debris --need to remove cover to access the bottom of shifter ---and possible shift interlock failure

is it a linkage issue? if the shift lever is working and you can feel the detents, check your fluid make sure it is full and clean, if not you could have internal issues with the trans

Does the engine start ? Is this a automatic transmission vehicle ? Do the brake lights work when you press on the brake pedal ? It probably has something to do with the Automatic Transmission Shift Lock
The brake transaxle shift interlock (BTSI) system consists of the body control module (BCM), powertrain control module (PCM), BTSI solenoid, stop lamp switch, and PRNDL selector switch. The BTSI system prevents the driver from moving the shift lever out of PARK unless the brake pedal is depressed while in RUN or CRANK.
The BCM controls the output to the BTSI solenoid by grounding the solenoid which energizes it, preventing shifting out of PARK. When the BCM receives input from the PCM over the Class II link that the transaxle is in PARK and the brake pedal is depressed, it will stop grounding the BTSI solenoid or de-energize it which will allow shifting. After the transaxle is moved out of the PARK position, the BCM shall monitor the status of the PRNDL serial data message sent by the PCM and shall continue to de-energize the solenoid until the transaxle has been returned to the PARK position.
In the event that the serial data messages are never received (approximately 5 seconds) by the BCM from the PCM, the BCM shall de-energize the solenoid to allow shifting. The transaxle can be shifted from PARK by placing the ignition switch in the ACC position. This eliminates power to the solenoid.

Do you have column or floor shifter ?
All automatic transaxle models use an electric park lock system. Within the housing assembly, a lock cylinder is connected to an actuator which rotates and engages on the electric park lock solenoid. When the floor-shift lever is not in the park position, the actuator disengages from the electric park lock solenoid slider. This allows the lock cylinder to move to the lock position. With the shift lever in PARK and the lock cylinder in LOCK, the actuator cam is positioned against the electric park lock solenoid slider. This prevents the shift lever from shifting out of the PARK position.
The column-shift automatic transaxle model uses a flexible cable actuator instead of an electric park lock system. One end of the cable is attached to the gate assembly. The other end of the cable is attached to the column mounted housing assembly. This system functions similarly to the floor-shift ignition lock system.
The manual transaxle model uses a push button lock cylinder. A clutch start switch is used. The clutch pedal must be pressed before the engine will crank. Refer to Park Lock System Check .
CAN you turn the key on ?
The gear selector does not shift out of PARK with the brake pedal depressed and the ignition switch in RUN.

1st, have someone step on brake pedal while you check to see if your brake lights are working, if yes proceed to step 2, if not check your brake light fuse(Left side of dash fuse#20- 10amp)IF fuse is good replace brake light switch on brake pedal. 2nd Step (brake lights ok) Turn key on engine off, press and release brake pedal several times slowly, listen for a click and and pulse on shifter handle. IF yes you have a shifter malfunction replace shifter assembly. IF no, inspect shift interlock solenoid and or relace solenoid and cable. You should see a small access cover about the size of a peanut around base faceplate of shifter assembly use small screwdriver and remove cover, use screw driver to press button underneath plate and release shifter into reverse and drive gears(this is manual overide) if you need to move vehicle in the meantime.

Hope this helps your out. I know the diagram and locator is a bit blurry but hopefully it gets what you need.

turn engine off. Turn key to OFF position, (no lights on dash lit). Step on brake, pull shift lever to neutral. start car, put in drive and go. this is emergency bypass.

When the key is ON, the shift lock soneoid is engaged and won't release till the brake is applied. Since you don't have brake lights, it means the solenoid won't unlock.
check for a blown fuse or a bad brake switch on the brake pedal.

OFF is the first click clockwise from LOCK. it goes, LOCK, OFF, ON, START.

replace brake light switch on brake padel ......brake light and inter-lock run through it....

probably due to safety on brake pedal, it will not allow you to move selectoer from park.
