Check brake light switch behind brake pedal remote start has to be wired into switch so vehicle will shut down when brake is depressed when put into gear without ignition switch turned on. possible bad connection on switch or wires are not attached.

How to replace an Ignition 1990 Mercury Grand Marquis

Good Evening. If your ignition still turns this will be an easier scenario. Straight down from your key cylinder towards the middle of your coulmn you will see holes for the screws that hold the cover together and you will also see 1 hole without a screw in it which is the one you will need to push a 1/8 drill bit up through there, you will turn the ignition forward and you will feel the bit move up, at that point pull the ignition cylinder out. If your ignition does not turn, get a little longer bit and you will have to drill that pin out and then pull your ignition out. I hope this helps and you have a good evening.

Car wont go out of park

do the brake lights work ?
they probaly do not,there is a brake light switch on the brake pedal lever,there is most likley a broken wire at this switch.If wire is broken repair wiring.
If this is the problem and you are unable to repair your self,do not start vehicle,put key to run position,then pull shifter into netural,then start vehicle and now you will be able to drive to get repaired.Remember if this is your problem you have no brake lights,be careful.
