It sounds like you over heated the engine and have damaged the head gasket. do not drive and have you car looked at more in detail to confirm the head gasket is indeed the problem
I have had the parking lights on my 1998 forester stay on w/ no way to turn off. Used the remote door lock to lock and unlock car and the lights went off?????????? This has happened twice with the same solution
I have a few trouble shooting tips for the problem with your Subaru Forester key fob.
1) Make sure you have the correct key fob part number. There are a couple different part numbers that are almost exactly the same.
2) Wipe the board
The board inside your remote can get a lot more filthy than you think! When the board is dirty it can prohibit the contact to the circuit board when you push down on the button. Simply wiping the circuit board off can make your key fob like new again!
3) The old car battery reset trick
I know this sounds absurd, but it works sometimes and is worth trying. If you exhausted all of the options above, disconnect bot terminals on your car battery for 10 minutes. Then reconnect them and try your key fob. This has worked for many people and I have no idea why. If you do, please comment below to explain.
4) Not sure where you bought the new key fob from, but some of the suppliers on eBay can be knock off quality. Try sending the one you purchased back and order one from here:

Sounds like your in tank pump isn't working.....and you have no fuel pressure at the fuel rail on the engine. See if you can tell that it turns on when you turn the key on....I'm not familiar with Subarus so I don't know if you can hear them spin up or not......Most any shop can tell you if you have fuel pressure at the rail....the other way is to loosen the fuel line at the rail and turn the key to on ( not crank) and see if you have fuel leaking from the loosened connection.
That most likely is the brake lights staying on because the brake light switch under dash is out of adjustment and the brake pedal is not touching the button to shut it off. Possibly the spring is disconnected that pulls the pedal up against the brake light switch button. Check this out.
Without seeing them my experience says they are clips that have two pieces. Simply put a screwdriver in the slot and turn like u do a screw but be very careful these are very fragile. When they are almost out pull cover off
could be condensation leaking from a small hole. I have seen some mufflers with a hole about 1/16" just for that purpose. It would do you some good to try and pinpoint exactly where it is coming from. Also, if you are not loosing any coolant, probably nothing to worry about. For coolant to come out exhaust, in most cases, you would have to have coolant entering a cylinder and it would show up in poor performance, very white smoke out exhaust while driving, and lose of coolant.
If it can be jumped at the solenoid then I would check out the ignition switch or the actual key cylinder insert. Some key inserts have plastic tabs on the sides or end and these will wear over time
Hi to reset computer just unhook the battery leads for an hour or so, Also check your fuses again, this time with a tester. Sometimes the break in the fuse wire is so small you miss it. Also you may have a loose connection(fuse not pushes all the way in). Check your relay switches in the black box in the engine bay as well as the fuses in the same box. Hope this helps.
You mention it is winter , not sure where you are , but how cold does it get ,in other words are you using the aircinditioner/heater in the vehicle, and when last was the vehicle serviced,
Warming the car up is a good thing and should not use a noticible difference in the consumption.
LAst if you can take the vehicle to a dealer and ask them to read the ecu codes and see if the computer is reporting any problems could be something as simple as a dirty filters or throttle body , worth a try, let me know how it goes.
