2001 Ford Taurus Fuel pump inop

You have a no start condition !!!
and fuel pump was tested and it is OK but had no power to it ?????!!!!
was the Intertia fuel shut off switch checked ??
do you have power at it
switch is located in the trunk right rear by the wheel well
what do you have for engine ?
how many valve ?

Vehicle is an 01 Taurus SEL - Key on, no fuel pump activation or sound. 12 volts is at the connector immediately beneath the spare tire that connects to is a small tubular cylinder about 2 inches long - 1/25 inch O.D. the other side of this electrical device has a fluid "T" connection - one being the output side that connects to a cavity (plastic rectangular box with two compartments) with fuel output line going to engine compartment. The other side of this cavity looks like the fuel feed into the cavity from the gas tank.

What is the funciton of this device? Is this cyllinder the fuel pump? The inertia switch checks OK and is not tripped. The voltage at the inertia switch connector measures about 6.6 VDC across the terminals with it disconnected.

Here's a P/N I found on this mystery electrical cylinder under the spare tire compartment (car underside and protected by a plastic shroud): FORD F7DE-9F945-AA - also, 1B4233-1. A Google search on both turns up porno sites ?????

Motorcraft parts search doesn't relate to either of those numbers.

Sure would like to know what this critter does and if it is the culprit. It has voltage on it but no action.

Thanks

evaporative emission valve !
has nothing to do with the fuel pump and its operation
if you have battery volts at the fuel pump connection and or in and out the shut-off switch
when 1st key on and when cranking and no fuel pressure
fuel pump no good drop fuel tank and replace fuel pump, its located inside the tank

Replaced the fuel pump and it now runs. Thanks for the help.
