Replacing the fuel pump on a 2005 Ford Freestar is a complex process. Before attempting to replace the fuel pump, it's important to check that the battery is working and that all cables have clean, tight connections. If the battery is weak, all you will hear is the starter solenoid clicking. You should also check for any leaks where air might be pulled into the line, which would cause a stuttering engine. Once you have established that the fuel pump is faulty, you will need to remove it from the tank through an access panel above the tank in the passenger compartment. If there is no access panel, you will need to drain the fuel from the tank and then lower the fuel tank from the vehicle to gain access to the pump.

Check the battery
Before replacing the fuel pump on a 2005 Ford Freestar, it is important to check the battery. If the battery is weak, all you will hear is the starter solenoid clicking. Make sure that all of the cables have good, clean, tight connections. Most auto parts stores can test your battery to see what shape it is in.
To replace the fuel pump, you will need to locate the electronic blend door actuator under the dash. You may have to remove the dash to get to it. You will want to make sure that there is power coming into the new switch and going out to the Blend Door Actuator (BDA). If there is no power to the switch, you will need to find out why and fix the broken wire. If you have power to the motor but it won't move, then replace the BDA. Make sure the black wire to the BDA is grounded. Test the orange wire going to the BDA and the yellow wire from the BDA to the switch for positive power.
Once the pump is out, any reusable brackets and pick-up screens are attached to the new pump, then the new pump is installed. If the fuel system uses an in-line external filter, a filter is often replaced. All hoses and electrical connections are re-established. Fuel is added to the tank and the engine is run to test for leaks. Usually, it’s still safe to drive, but the pump may lead to an overheated engine and catalytic converter.
It is important to note that you should be sure that you need to replace the pump in the first place. You can get a pressure check to make sure the right pressure is pushing gas to the motor, and check for any leaks where air might be pulled into the line, which would cause a stuttering engine.
