No , there wasn't a flex fuel version of the 3.0 liter " Vulcan " V6 engine
available in the 1999 Mercury Sable ( according to the Owner Guide )
Mounted on top and inside the fuel tank.
You look under the pump and see if it's leaking. It's very obvious if it is.
It could be the wire is disconnected that's attached to your break peddle...My 1994 merc sable wouldn't go into gear from park and there were two wire connected to my brake peddle and one was disconnected. when i connected it again, the vehicle went into gear. Hope this helps
towing capacity of 2003 merc. sable is #1000 class 1 hitch
Check for a broken wire in the hinge area. That's where wires flex and usually break, causing intermittents.
On a Mercury Sable V6 : firewall 1-----2-----3 4-----5-----6 front of vehicle > driver
Should be a label posted either on door jamb or on fuel cap filler door
where in my mercades c230 kompressor is the fuel cap release
The fuel pump is in the fuel tank and the tank must be removed to access the fuel pump.
i have a 1999 25 hp merc motor used i and i have asked the dealer close to where i live and they said to mix 50/1 . so that's what i have been using / with no problems
