On my Merc Sable ( fancy Taurus ) it says to unplug fuel inertia
switch and run engine until it stalls. Later, after filter change,
plug back in, turn key on but don't try to start. Do this 3 or 4
times, and then try to start engine.

This is on a FORD. I don't know if OP's vehicle has a fuel inertia
switch. Would be nice if it did, but he can just unplug wires going
to fuel pump? Cable harness?

GM doesn't use that item thank god. The GM system has redundancy. If the
fuel pump relay dumps, it will still start once oil pressure comes up. If
you know where the inertia switch is on a "found on road dead", you can
smack that area on the outside of the car with the palm of your hand and
disable the car. Most people don't know about the bloody thing, so they end
up calling a wrecker for a tow to the shop. More than a few tow truck
operators don't know about it ether. If the inertia switch goes bad your
not going to get the vehicle started. and there have been more than a few
times I have had customers tell me they hit a bad pot hole or a bump and the
car just shut down. Great idea ford.

It is to keep gasoline from burning you alive in a crash. So I don't
think it is a -bad- idea as long as you know where it is, what it
does, and how to Reset it. On my car, BIG red switch to Reset it. In
trunk near rear wheel well. Can't imagine anybody not noticing this
monstrosity, especially with its neon-red dayglo color ;-)

Also, front crash sensors, one on each side of radiator. IOW, don't
bump into ANYTHING with this car, including a shopping cart, or you
might not get home except in a taxi.

There are several ways that you can do this -- most common is to disconnect the
fuel pump at the source -- sending unit @ the fuel tank.- Start the engine, run
until engine dies! Another way is to relieve the pressure by using a special
tool that fits onto the fuel rail test connector!



R/R fuel filter should take you no more than 20 mins to complete

<Gasp> NO!!!!
FORD's = Found On Road DEAD, Fix or Repair Daily, Factory Ordered Road Disaster,
Factory Ordered Rebuilt Dodge, For Only Retarded Drivers,
Ford Only Rolls Downhill!!!

try this -- take a large hammer and hit the rear bumper hard -- guess what
happens? <grin>

Well way back in 1971 Chevy came out with a new car called the Vega. A
great piece of
automotive engineering that was unfortunately about 20 years a head of the
times. No steel sleeves
in the aluminum block, silicon injected into mold as aluminum begins to
solidify, silicon goes to surfaces.
Special hone process to smooth silicon in cylinders, chrome molly rings (one
of the first production
cars to use them). and a strict oil change recommendation. So you have
chrome moly rings riding on
thin layer of oil on a thin layer of silicone. If you loose oil pressure,
the rings scrap the silicone off
and score the cylinder walls. So GM tied the oil pressure sending unit to
the fuel pump circuit(Yup,
another first for american iron, in tank electric fuel pump). Nice side
affect, if car is in accident, and
fuel line busted, engine stalls, oil pressure goes away, fuel pump shuts
off. This system worked so well
on the accident side, that GM continued to use it on vehicles with electric
fuel pumps.
(I have a fond spot, make that a severe love affair with Vegas)

You and I as gear heads know about the inertia switch. Grandpa and Grandma
Smith haven't a clue,
and I fear often get taken to the cleaners over that inertia, as do many
other ford owners who like 70%
of car owners would be hard pressed to tell you where the oil dip stick is
on their vehicle.

Tell me this is Satire.
Every Vega I've ever seen was so shot-through with RUST it looked like
it came from a salvage yard. The body work on those Vegas left much
to be desired.

Today's engines are being sold as "maintenance free" to the public,
but you and I know _better_. In some ways, they are easier to work
on; less moving parts and gizmos, in some ways they are harder to work
on; computer modules with secret algorithms and special factory
programming. It all washes out in the end. You take care of your
car, IT will take care of you. Ignore your car, it will let you down,
sooner if not later. Some people have money to burn; I'm not one of
em.

Air bags only deploy at a variable velocity based on weight detected
in front seat(s) and distance between passenger and steering column as
measured by electric-seat motor monitoring equipment. So nothing will
happen, except you will get a police ticket for criminal damage to
property. Or maybe you will trigger fuel inertia switch, which is
re-settable in all of about 3 seconds.

True, true. None whatsoever. But my dog likes me, so what more can a
guy ask for?
