Just take the covers off the steering column, switch is there.
Drain plug for what?
open the hood, look down between the rad. and the engine. There it is.
The 1986 Mercury Marquis does not have a fuel cutoff switch. The fuel pump does have a fuse, of which could render it as nonworking.
Only the 2.3L HSC Inline 4 will fit in the 1986 Mercury Topaz. If everything in the engine bay were gutted, perhaps something larger such as a 3.0L V6 from a 1992-1994 model MIGHT fit but it would require a complete running 92-94 Ford Tempo or Mercury Topaz with the V6 engine as a donor car (and, if you could find such a car, it would be more worth your time/money to invest in it v.s. a 1986 model). The automatic transmission from a Taurus WILL NOT WORK in a Tempo/Topaz.
THE FUEL FILTER IS UNDER THE HOOD ON THE WHEEL WELL, LEFT OF THE ALTERNATOR.
