Fuel Pump Failure

This problem can cause loss of pressure when fuel is sent to the engine for combustion. Replacement is the only solution for this. Before replacing the faulty fuel pump, make sure you release the fuel pressure. Locate the fuel pump fuse or relay and start the car. While the engine is running, pull out the fuse or relay. The engine will then die, which signifies that you have released the pressure. Now, you can start removing the fuel pump. Detach the fuel lines from the pump by loosening the hose clamp or fitting. Gas may leak as you perform the process, so have something that will catch it on hand. Remove the electrical wirings as well as the plugs or screws that hold them. Remove the faulty fuel pump and install the new one. Reconnect the wires and the fuel lines. Be sure to secure everything by tightening the necessary bolts and clamps.

Vibrating Steering Wheel When Braking

Solution: The parts to look at in this situation are the tires, suspension, and brake discs. Although the problem most likely lies on the front brake discs, it is better to check tire and suspension wear first before replacing the brake discs. When replacing the brake disc or other brake components, make sure to loosen the lug nuts before lifting the car with a jack. Completely remove the lug nuts, wheel, and tire once the car has been lifted. Remove the brake caliper to expose the brake disc. Remove the bolts securing the brake disc and slide the warped disc off the hub. If you're having trouble removing the disc, use a dead blow hammer to tap it off. Install the new disc along with the new brake disc screws. Reinstall the brake caliper, wheel, tire, and other hardware. Make sure all bolts are securely tightened.

Busted Headlight Bulb

Solution: This DIY repair has been a common problem especially for 2008 Mercury Milan owners because they find it difficult to access the bulb. You can check the owner's manual for other models, but for Milans, there is a bulb-access door right under the front passenger-side wheel. From there, all you have to do is remove the screw and the bulb-access door, and you will be able to get your hand on the busted bulb. Replace it with a new one and connect it to the fixture. Screw back the bulb-access door.

Burned Out Coil

Solution: Disconnect the negative battery cable from the battery terminal. Remove the engine cover and disconnect the electrical connectors. This includes disconnecting the spark plug wires from the distributor or ignition coil. You can access these parts once you remove the distributor cap. Detach the ignition coil from its mount. Next, using a wrench, remove the retainers and the coil. Install the new distributor or ignition coil. Put the retainers back, mount the coil back, and connect the spark plug wires to the distributor or ignition coil. Once you have put back all the parts and wires, you can now reconnect the battery. Mercury owners can do preventive measures by servicing their cars' ignition system every 50,000 miles.
