Replacing Fuel Pump In 2007 Ford Taurus: Step-By-Step Guide

The fuel pump in a 2007 Ford Taurus is located inside the fuel tank. To replace it, you will need to disconnect the battery, remove the fuel tank, and replace the pump. This process can be complex and time-consuming, and it is recommended that you have some experience with auto repair before attempting it. The average cost for a Ford Taurus fuel pump replacement is between $916 and $1,165, with labour costs estimated between $161 and $203, and parts priced between $755 and $962.

Check for power to the fuel pump

To check for power to the fuel pump of your 2007 Ford Taurus, you can try the following:

Firstly, check the fuel pump relay. Pull the relay out and run a jumper wire from the hot to the lead for the fuel pump. If this does not power the fuel pump, then the issue is likely either the connection or the pump itself.

You can also check the power wires in the harness. Based on a 2006 Taurus wiring diagram, the White/Red and Black/Pink wires are the power wires. You can check the Pink/Black wire with a multimeter to ground to see if power is there. You should also check with a test light to ensure that both voltage and current are available.

Another thing to try is to give the intake a shot of starting fluid to see if the car tries to fire up. If it doesn't, then it is not a fuel issue.

Finally, you can try to hotwire the pump directly to +12 V and ground to see if it will build pressure. With the pump running at full voltage and the engine not running, the pressure should quickly shoot to 60+ psi.

Disconnect the battery

Disconnecting the battery of a 2007 Ford Taurus is a simple task that can be completed in a few minutes. Here is a step-by-step guide on how to do it:

Locate the battery: The battery of a 2007 Ford Taurus is typically located in the engine bay, near the front of the vehicle.

Access the battery: Before you begin, make sure the engine is turned off and the key is removed from the ignition. Open the hood of the car and locate the battery. You may need to remove any plastic covers or brackets that are holding the battery in place.

Identify the negative and positive terminals: The battery will have two terminals, a negative (-) terminal and a positive (+) terminal. It is important to identify these correctly before proceeding. The negative terminal is usually marked with a "-" symbol and a black cable, while the positive terminal is marked with a "+" symbol and a red cable.

Disconnect the negative terminal first: Using an appropriate size wrench or socket, loosen the nut or bolt that secures the negative battery cable to the terminal. Once it is loose, carefully remove the cable from the terminal. You may need to wiggle it gently to detach it.

Disconnect the positive terminal: Similarly, loosen the nut or bolt securing the positive battery cable and remove the cable from the terminal. Ensure that the cable does not touch any metal parts of the vehicle to avoid creating a short circuit.

Secure the battery cables: To prevent the cables from accidentally touching any metal parts, you can use cable ties or tape to secure them away from the battery.

With these steps, you will have successfully disconnected the battery of your 2007 Ford Taurus. Remember to exercise caution and wear appropriate safety gear when working with car batteries.

Remove the access cover

To remove the access cover of your 2007 Ford Taurus to replace the fuel pump, you have two options:

Option 1: Drop the Tank

Firstly, you'll need to drain the tank. Place the rear of the car on ramps and remove the rubber filler tube. Insert a hose and siphon out the remaining gas. Next, break free the tank strap bolts and cut a couple of lengths of all-thread rod to use as long bolts for installing the tank. Get them in place and tighten the nuts to draw the tank up.

Option 2: Create an Access Panel

You can also create an access panel by removing the back seat and cutting a hole in the trunk floor. This method is more dangerous and may take longer than dropping the tank. You can use a grinder to cut a square, but be careful not to go all the way through. Instead, perforate it enough so you can lightly punch it open. Then, open and undo the wires and lines before proceeding with the fuel pump replacement.

Safety Warning: Working with the fuel system is dangerous, and there is a risk of fire. Take all necessary precautions and consider getting a repair shop to handle this job if you are not experienced in auto repair.

Replace the pump and pre-pump filter screen

To replace the pump and pre-pump filter screen of a 2007 Ford Taurus, you will need to follow these steps:

Step 1: Disconnect the battery

Before beginning any work on the fuel pump, it is important to disconnect the battery to reduce the risk of fire.

Step 2: Remove the access cover

For pumps located inside the fuel tank, there is usually an access cover that needs to be removed. In some cases, you may need to drain the fuel before removing this access panel.

Step 3: Replace the pump and filter screen

With the cover off, you can now access the fuel pump and pre-pump filter screen for replacement. Carefully remove the old pump and filter, taking note of the electrical connections and the positioning of the assembly. Install the new pump and filter, ensuring that the electrical connectors are hooked up correctly.

Step 4: Reinstall the access cover

Once the new pump and filter are in place, secure the locking ring back onto the top of the pump assembly. Slide the fuel tank back under the car, and lift it onto the floor jack. Reconnect all the plastic hoses and the electrical connector clip on top of the tank.

Step 5: Final checks

Jack the fuel tank back into place and reconnect the tank filler and vent hose. Reinstall the tank strap bolts. Double-check that all connections are secure and properly hooked up.

Now you can lower your car off the jack stands and refill your gas tank if you had to siphon it out. Your new fuel pump and filter screen should now be installed and functioning correctly.

Check for fuel leaks

It is important to check for fuel leaks after replacing a fuel pump. Working with the fuel system is dangerous, so take all precautions to prevent a fire. After the repair is done, be on the lookout for fuel leaks or odors. If you see or smell gasoline, do not start or drive the car, and do not park inside your house or under a covered structure. Have the car towed to a shop for inspection and repair.

If you notice a fuel leak, it could be due to a number of reasons. Firstly, check if the fuel pump is leaking. A failing fuel pump may not create enough pressure in the fuel system, causing a loss of engine power or preventing the car from starting. If the fuel pump is not the issue, then the fuel filter may need to be replaced. The intake screen for in-tank fuel pumps should also be checked and replaced if necessary.

Another possible cause of a fuel leak is a faulty fuel vapor canister. This can be diagnosed by noticing a steady drip of fuel puddling on the ground after filling up the gas tank. To fix this, the vapor canister and the valve at the rear of the vapor canister should be replaced. If this does not solve the issue, there may be a problem with the fuel vapor canister hose, which may need to be inspected and replaced.

Additionally, repeatedly running the fuel tank low or driving with clogged fuel filters can put additional strain on the fuel pump, shortening its lifespan. Therefore, it is recommended to replace the fuel filters at the same time as the fuel pump to prevent future leaks.
