Re: 1993 Ford Taraus 3.0L F/I Having problems...
Fuel pump is in the tank, filter is just ahead of the passenger side rear tire. You can check the fuel pressure at the fuel rail where there is a schrader valve to connect a fuel pressure guage to. It looks like a tire valve stem.
Pressure should be ~40 lbs with key on engine off or no vacuum, 35 lbs with the engine running at idle and 30 lbs at high vacuum situations like coasting.
If changing the fuel filter make sure the new one has new plastic clips in them.
