Something is draining my battery to where I have to jump start it every morning and I pulled all fuses and relays and the light never went out to indicate something was draining also my parking break appears on the display screen that it is engaged and it is not
Have your alternator checked for free at an autozone, advance or O'Reilly auto parts. If the diode trio goes out it will cause a drain and kill the battery overnight. Also have them check the battery for a dead cell.
If your brake lights stay on it is a simple matter to push the switch back into its' holder while pushing the brake pedal down. When you release the brake pedal it will adjust itself automatically.
a 6ya Mechanic can help you resolve that issue over the phone in a minute or two.

Start with the simple things. Auto parts stores can test your alternator for bad diodes, which if failing can cause this. Next, disconnect battery neg and hook up amp meter, then remove one fuse at a time to find which one changes the reading, then figure out what that fuse powers and check for something like a glove box door loose and not turning off the light. I have even seen a relay sticking on, or one being replaced by the wrong type such that the pins were wrong and the coil was always on. You can find this by feeling the top of each relay with everything turned off. If one is warm or hot you have found the problem.
Lincoln sometimes has similiar troubles. Ya might try pulling some of the relays.
I'd start with one relay at a time like the battery delay relay, then maybe a fuel relay.
These relays get "signals" to energize usually from a GEM Module...or rather stay energized.
You may need to test for a parasitic power drain, for example a horn switch that is stuck closed causing the horn relay switch to stay on continuously even if the wire was unplugged from the horn.
You will need multimeter to test for a parasitic power drain.
1. With the key off, disconnect the negative battery cable.
2. Connect the black multimeter test lead to the negative battery post, connect the red test lead to the negative battery cable.
3. With the meter set to the DC milli-amps scale note the current draw displayed. If it is over 20 mA, there is likely something drawing power that shouldn't be.
4. Leaving the meter connected have an assistant pull fuses one at a time (replacing them before pulling the next) until the meter reading drops. The circuit that this fuse powers is where the problem most likely is.
it is the automatic load leveler that pumps air into the back shocks to level the car so it rides better when there are lots of people or weight in it. it is in the frontof the car opposite the battery, just disconnect it. had the same problem on my 1990 olds 98.
there is a drain in the system,
all you need is a test light
un hook the positive battery cable
connect the test light between the positive lead and the battery terminal
if there is a drain the light will lit
remove each fuse at a time ( put it back if the light does not go out )
which ever fuse that you remove and make the light goes out, that's the one that cause the drain.
check and fix that system
You'll need to remove screws that are by the door handle,
arm rest, under door and side of door and then gently pull back on the
panel as there will also be retaining clips attached and you don't want
to break them. If needed, you can pull back the weather seal
(can't reuse it, but it's not that important) and you will be able to
access everything inside the door
