SOURCE: Intermittent fuel pump engagement when turning key - 2001 Taurus
try cleaning the connector that goes to the fuel pump, sometimes they corrode on inside. If that does not fix, test the wires feeding fuel pump with a multi meter until the condition shows itself again, if voltage drops to zero or very low then wiring problem, if voltage is unchanged with problem and fuel pump is not working and connectors are all clean, try replacement of fuel pump.
SOURCE: instructions on how to replace fuel pump on 2001
the best thing for you to do is stop by your local library and get your hands on a Haynes auto repair manual for your car you will have to drop the tank but i always checkout the fuel pump relay before i do wish you the best of luck Michigan Man
SOURCE: how do i reset fuel pump switch on 2001 ford
it in the lower left corner of trunk, all you do is push in button ,thats it if thats your problem it will reset.hope this helps.

Several thnigs to check there; review all informastion disponible to do it and solve this...
P0356 - Ignition Coil F Primary/Secondary Circuit Malfunction
The ignition signal from the Powertrain Control Module (PCM) or Electronic Control Module(ECM) is sent to and amplified by the power transistor. The power transistor turns ON and OFF the ignition coil primary circuit. This ON/OFF operation induces the proper high voltage in the coil secondary circuit.
Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power
- The engine may be harder to start
- Engine hesitation
Possible Causes:
- Open or short in the ignition coil circuit
- Ignition coil circuit shorted to ground
- Ignition coil connector
- Damaged ignition coil
- Damaged PCM or ECM
Possible Solution:
- If damage, repair ignition coil circuit
- Replaced ignition coil
- Replaced PCM or ECM

P0152 - O2 Sensor Circuit High Voltage (Bank 2 Sensor 1)
The heated oxygen sensor 1 is placed into the exhaust manifold. It
detects the amount of oxygen in the exhaust gas compared to the outside
air. The heated oxygen sensor 1 has a closed-end tube made of ceramic
zirconia. The zirconia generates voltage from approximately 1V in richer
conditions to 0V in leaner conditions. The heated oxygen sensor 1
signal is sent to the ECM. The ECM adjusts the injection pulse duration
to achieve the ideal air-fuel ratio. The ideal air-fuel ratio occurs
near the radical change from 1V to 0V.
Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- High Fuel Consumption
- Excessive Smoke from Exhaust
Possible Causes:
- Harness or connectors (The heated oxygen sensor 1 heater circuit is open or shorted.)
- Front Heater oxygen sensor heater (Bank 2) may be faulty
Possible Solution:
Replacing the O2 Sensor 1 usually takes care of the problem
------------------------------------------------------------------------------------------------------------------------------------------------
P0174 - Fuel Injection System Too Lean Bank 2
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual
mixture ratio can be brought closely to the theoretical mixture ratio
based on the mixture ratio feedback signal from the heated oxygen
sensors 1. The ECM calculates the necessary compensation to correct the
offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (The
actual mixture ratio is too lean.), the ECM judges the condition as the
fuel injection system malfunction and light up the MIL (2 trip detection
logic).
Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Excessive Fuel Consumption
Possible Causes:
- Intake air leaks
- Front Heated oxygen sensor may be faulty
- Injectors may be faulty
- Exhaust gas leaks
- Incorrect fuel pressure
- Lack of fuel
- Mass air flow sensor may be faulty
- Incorrect PCV hose connection
Possible Solution:
Dirty air filter of faulty air flow sensor are common causes of the problem.
------------------------------------------------------------------------------------------------------------------------------------------------
P2197 - DODGE - Sys Too Rich at Hier Load Bank1
Means that the O2 sensors on each bank are seeing WAY
too much oxygen in the exhaust gas. In normal operation the signal from
the O2 sensors should swing back and forth between rich and lean.
Your sensors are locked on lean.
Those codes are the same as P0174 (and P0171). Sounds like you have a
vacuum leak somewhere. Most common place is the PCV elbow where it
connects to the throttle body adapter.

Hope this helps; keep in touch.
