Check the fuses- Shift interlock is the same circuit as brake lights. As a temporary measure - try to turn the key to 1st (unlock) position shift to neutral to start vehicle and then shift to Drive.

It could be a fuse. If the brake lights do not turn on when you press the brake pedal check your fuses under your dash.

APPLY BRAKES AND SEE IF BRAKE LIGHTS COME ON. IF NO BRAKE LIGHTS, REPLACE THE BRAKE LIGHT SWITCH LOCATED ON THE BRAKE PEDAL ARM AND THIS SHOULD ALLOW YOU TO SHIFT OUT OF PARK. IF THAT BRAKE LIGHT SWITCH IS BROKE, YOU WON'T BE ABLE TO GET IT OUT OF PARK

You don't mention what year of Mercury Grand Marquis but the owners manual will explain what to do if the transmission gear shift lever will not shift out of ( P / PARK ) with the brake pedal depressed ( it has what Ford calls the " brake shift interlock " ) As of August 6 , 2012 you can still view the Mercury Grand Marquis owners manual online ( back to the 1996 model ) at : www . motorcraft service . com ( no spaces ) Click on Owner Guides


Why would your brake lights and right turn signal not work and you have to turn the key half way to start the car in neutral so you will be able to change gears to drive on a 1992 Grand Marquis?

Check fuses, If brake lights do not work, transmission will not shift out of park. Brake light circuit is common to shift interlock. That's why you must step on brake to release interlock prior to shifting out of "Park" If stop lights are not working interlock will not release.

Just turn the key to the first position, ( not on ) and then you will be able to shift to neutral and start the car from there. Have the fuses checked and check the shifter sensor on the brake pedal.
