2004 Chrysler Town and Country Fuel Pump: Complete Guide to Symptoms, Replacement, and Best Options

The bottom line: If your 2004 Chrysler Town and Country is hard to start, stalls unexpectedly, or loses power during acceleration, the fuel pump is likely failing. The fuel pump is located inside the fuel tank, and you need to replace it with a direct-fit assembly that includes the sending unit for reliable performance.

Understanding the Fuel Pump in Your 2004 Chrysler Town and Country

The fuel pump in your 2004 Chrysler Town and Country is an electric pump mounted inside the fuel tank. It delivers fuel from the tank to the engine at a specific pressure. For the 3.3L V6 engine, the factory fuel pump operates at 80 to 95 PSI and delivers 30 to 45 gallons per hour. The pump is part of a module assembly that also includes the fuel level sending unit, which tells your dashboard gauge how much fuel is in the tank.

This generation of Chrysler minivan uses a returnless fuel system. The pump module sits inside the tank and sends fuel through a single line to the engine. The fuel pressure regulator is built into the pump module, not on the engine. This design means the pump must maintain precise pressure for the engine to run correctly.

Common Symptoms of a Failing Fuel Pump

A failing fuel pump in a 2004 Chrysler Town and Country shows several warning signs. Catching these early can save you from being stranded on the road.

1. Engine hard to start when cold. When the fuel pump check valve fails, fuel pressure drops overnight. The engine has to crank longer before it fires up because the pump needs to rebuild pressure in the fuel lines.

2. Loss of power during acceleration. If your Town and Country feels sluggish when you press the gas pedal, the pump may not be delivering enough fuel. The entry of dirt or debris into the pump causes the impeller and pump body to wear out, reducing the pump's ability to push fuel.

3. Engine sputters or stalls at high speeds. A weak fuel pump cannot keep up with the engine's demand for fuel at highway speeds. You may feel the engine hesitate or cut out temporarily.

4. Whining noise from the fuel tank. A healthy fuel pump makes a quiet humming sound. If you hear a loud whining or howling noise coming from the rear of the vehicle, the pump bearings are wearing out.

5. Engine misfires or rough idle. Inconsistent fuel pressure causes the air-fuel mixture to be too lean, leading to misfires and a rough running engine.

6. Intermittent engine performance. The car may run fine one day and act up the next. This on-and-off behavior is a classic sign of a failing fuel pump electrical motor.

Where Is the Fuel Pump Located?

The fuel pump on the 2004 Chrysler Town and Country is inside the fuel tank. The tank sits under the rear of the vehicle, behind the rear axle. On most models, you can access the pump by removing the rear seat and lifting a metal access panel. Some vehicles may require dropping the fuel tank from underneath to reach the pump module.

How to Diagnose a Bad Fuel Pump

Before you buy a new fuel pump, you should confirm that the pump is actually the problem. Here are the steps to diagnose the issue.

Step 1: Check the fuel pump fuse and relay. The fuel pump relay is located in the underhood fuse box. If the relay is bad, the pump will not get power. Swap the relay with a known good one of the same type to test it.

Step 2: Listen for the pump. Turn the key to the ON position without starting the engine. You should hear a two-second humming sound from the rear of the vehicle. If you hear nothing, the pump is not running.

Step 3: Test fuel pressure. Use a fuel pressure test kit to check the pressure at the fuel rail. For the 2004 Town and Country 3.3L, the pressure should be between 80 and 95 PSI. If the pressure is low or zero, the pump is failing.

Step 4: Check for clogged fuel filter. A clogged fuel filter can mimic a bad pump. The fuel filter on the 2004 Town and Country is located along the frame rail under the driver's side. Replace the filter first if it has never been changed, then test the pressure again.

Fuel Pump Replacement Options for 2004 Chrysler Town and Country

When you replace the fuel pump, you have several options. The best choice is a complete fuel pump module assembly that includes the pump, fuel level sending unit, strainer, and seal. This direct-fit replacement makes installation straightforward and ensures all components are new.

OEM and Direct Fit Replacement Part Numbers
The 2004 Chrysler Town and Country 3.3L fuel pump assembly is available under several part numbers: E7172M, P76061M, FG0482, SP7172M, and 5127562AB. These part numbers cross-reference to the same pump module assembly. The pump fits the following vehicles:

• 2004-2005 Chrysler Town and Country V6 3.3L (without Stow and Go seating)
• 2004-2005 Chrysler Town and Country V6 3.8L
• 2007 Chrysler Town and Country V6 3.3L
• 2004-2007 Dodge Caravan L4 2.4L and V6 3.3L
• 2004-2005 Dodge Grand Caravan V6 3.3L and 3.8L

What to Look for in a Replacement Pump

• Complete assembly. A full module with the sending unit and float saves time and ensures accurate fuel level readings.
• Includes gasket or seal. The tank seal is essential to prevent fuel leaks and vapor loss.
• Direct fit. Avoid universal pumps that require modification. A vehicle-specific pump bolts in without adapters.
• Pressure rating. The pump must deliver 80-95 PSI to match the engine's fuel system requirements.

Step-by-Step Fuel Pump Replacement Guide

Replacing the fuel pump on a 2004 Chrysler Town and Country is a job that a moderately experienced DIYer can handle. The hardest part is accessing the pump inside the fuel tank. Here is the process.

Safety First
Fuel is flammable. Work in a well-ventilated area away from open flames. Disconnect the negative battery cable to prevent accidental sparks. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Wear safety glasses and gloves.

1. Access the pump. Remove the rear seat cushion. On most 2004 Town and Country models, there is a metal access panel under the seat on the driver's side. Remove the screws holding the panel and lift it off.

2. Disconnect the electrical connector and fuel lines. The pump module has a wiring harness connector and two fuel line connections. Use a fuel line disconnect tool to release the quick-connect fittings. Have a rag ready for any fuel that drips out.

3. Remove the locking ring. Use a special fuel pump locking ring tool or a hammer and punch to turn the retaining ring counterclockwise. Lift the ring off and pull the pump module straight out of the tank. Be careful not to bend the float arm.

4. Transfer components. If you bought a complete assembly, you can install it directly. If you bought just the pump, you need to transfer the sending unit, strainer, and gasket to the new pump.

5. Install the new pump. Lower the new module into the tank. Make sure the float arm is not bent and moves freely. The gasket must sit flat against the tank opening. Install the locking ring and tighten it securely clockwise.

6. Reconnect everything. Reconnect the fuel lines and electrical connector. Install the access panel and seat. Reconnect the battery.

7. Test the system. Turn the key to the ON position without starting the engine. Let the pump pressurize the system. Check for leaks around the tank opening and fuel line connections. Start the engine and verify that the fuel gauge reads accurately.

Why You Shouldn't Delay Fuel Pump Replacement

Driving with a failing fuel pump can cause more damage to your engine. When the pump cannot deliver enough fuel, the engine runs lean, which means too much air and not enough fuel. Lean conditions cause high combustion temperatures that can damage the catalytic converter and oxygen sensors. A completely failed pump leaves you stranded.

The fuel pump on the 2004 Chrysler Town and Country typically lasts between 100,000 and 150,000 miles. If your van has over 100,000 miles and you are experiencing any of the symptoms listed earlier, it is smart to replace the pump proactively.
