How can remove the rear seat on a 1990 mercury sable
Yes
According to my Chilton's Auto Repair Manual : For a 1990 Mercury Sable : ( 16.0 U.S. gallons or the optional extended range tank which is 18.6 )
In the relay block with the other relays.
On a 1990 Mercury Sable : The ELECTRIC fuel pump is INSIDE the fuel tank ( it is installed through an access hole in the top of the fuel tank )

Yes, but you'll have to pull the plenum first.
Your Ford/Mercury dealer can get the code. See "Related Questions" below for instructions on changing the lock cylinder
Usually that would be the case, however their are variations in both cars.

1990
Go online to any auto parts store and look up the alternator for both the 1990 and the 1999. If the part number is the same you're good to go.
