How to Replace a Fuel Filter
(DIY Complexity: Moderate / Time: 1.4 hours)

Parts:
1. Fuel Filter

Tools:
1. 3/8 in. Drive Ratchet
2. Hose Pincher
3. Flare Nut Wrench
4. Flat Head Screwdriver
5. Socket Set

Steps:
Step 1 Open the hood and locate the fuel filter. If the fuel filter is not in the engine compartment, follow the fuel line from the tank until the fuel filter is located.
o Tip: Safety Tip:Always wear safety glasses when working on your vehicle. Wear other personal protective equipment (PPE) when necessary, for example latex gloves or safety shoes.

Step 2 If the fuel filter has a clear case, inspect the filter element for dirt.

Step 3 If the fuel filter case is not see-through, remove it from the fuel line. Drain the fuel from the filter into a container and inspect the condition of the fuel.
o Tip: Caution: Before removing fuel lines or fuel related parts, make sure that the fuel pressure is relieved from the vehicle fuel system. To relieve the pressure in fuel injected systems, remove the fuel pump fuse and run the engine.

Step 4 Install the new fuel filter making sure that the flow is in the correct direction. The arrow on the fuel filter is the direction of flow from the tank to the engine.

Step 5 Secure the lines back onto the fuel filter. If applicable, reinstall the fuel pump fuse.

Step 6 Start the engine and check for fuel leaks.

Step 7 Test drive the vehicle to check for a rough running engine, hesitation, or lack of power.


Hope this help (remember comment and rated this).

The filter is bolted to the frame, held on with a large worm gear clamp. There are 2 U shaped plastic clips that keep the hoses connected to the filter. Remove the clips and wiggle the lines off. Watch for gasoline coming out the filter. You might want to start the car and unplug the fuel pump fuse to relieve the fuel pressure.

What should the fuel pressure be on a 2002 mercury cougar v6. car will turn over fine and sputter. it sounds like it really wants to start but will not run.


REPLACE FUEL FILTER FIRST.THEN CHECK FUEL PRESSURE,IT SHOULD BE 37 - 41 PSI. IF FUEL PRESSURE OKAY. A LEAKING OR STUCK OPEN EGR VALVE WILL CAUSE ENGINE TO SPUTTER AND SHUT OFF.

1999 mercury cougar. won't start...cranks...battery ok.


V6 ? 4CYL? Have you verified SPARK? Did anyone check the "fuel pump inertia switch?" Its in the right front kick panel. If it was a "Anti-theft Issue" the light would be on or flashing.
