1998 Chrysler Cirrus Fuel Pump: How to Replace, Symptoms, and What It Costs

If your 1998 Chrysler Cirrus is having trouble starting, stalling unexpectedly, or making a whining noise from the rear of the car, the fuel pump is likely failing. The fuel pump in your Cirrus is an electric unit located inside the fuel tank, and when it fails, you need to replace the entire fuel pump module. The average cost for a professional fuel pump replacement on a 1998 Chrysler Cirrus ranges from $1,145 to $1,316 at a dealership or independent shop, with parts costing about $572 to $632 and labor adding another $572 to $632 . DIY replacement costs are much lower, typically $50 to $300 for parts if you do the work yourself . This guide walks you through the symptoms, the replacement process, and how to choose the right parts for your 1998 Cirrus.

Symptoms of a Failing Fuel Pump in a 1998 Chrysler Cirrus

A bad fuel pump does not always fail suddenly. It often gives warning signs first. Here are the most common symptoms to watch for :

1. Engine won't start or stalls unexpectedly. A failed fuel pump cannot deliver pressurized gasoline to the injectors, so the engine either won't crank or will start and then die shortly after.
2. Whirring or humming noise from the fuel tank. Normally, a fuel pump is nearly silent. If you hear a loud whining or humming sound coming from the rear of the car near the gas tank, the pump is likely on its last legs .
3. Check Engine Light comes on. As the pump loses pressure, the engine may run too lean (too much air and not enough fuel). This triggers the Check Engine Light, often with codes like P0230 (fuel pump primary circuit) or P0231 (fuel pump secondary circuit low) .
4. Loss of power, especially going uphill or at high speeds. If the pump cannot maintain adequate pressure, the engine will sputter or surge when you demand more power .
5. Hesitation when accelerating. A weak pump struggles to supply enough fuel during hard acceleration, causing a noticeable lag.

Important: If you notice any of these symptoms, do not ignore them. Driving with a failing fuel pump can leave you stranded or cause additional damage to the fuel system .

How Much Does a 1998 Chrysler Cirrus Fuel Pump Replacement Cost?

Costs vary significantly based on where you get the work done and whether you do it yourself. Here is a breakdown based on real estimates for the 1998 Chrysler Cirrus:

Why the range? The 1998 Cirrus was available with a 2.4L 4-cylinder engine and a 2.5L V6. Some years and trims require slightly different parts, which can affect the price. Also, labor rates vary by region. In the Norfolk, VA area, dealership labor runs about $572 to $632, while independent shops charge similar amounts .

Where Is the Fuel Pump Located on a 1998 Chrysler Cirrus?

The fuel pump is located inside the fuel tank. There is no access panel in the cabin or trunk for this model. To reach the pump, you must completely drain and remove the fuel tank from the vehicle . This makes the job more labor-intensive than on some other cars.

How to Replace the Fuel Pump – Step-by-Step Overview

Replacing the fuel pump on a 1998 Chrysler Cirrus is a moderately difficult DIY job. It requires basic mechanical skills and the right safety precautions. Here is the general process :

Step 1: Safety First

• Disconnect the negative battery cable to prevent sparks .
• Relieve fuel system pressure. Remove the fuel cap, then start the engine and let it stall. Crank it a few more times to clear the lines .
• Place a fire extinguisher nearby. Work in a well-ventilated area.

Step 2: Tools and Parts Needed

• Floor jack and 4 jack stands
• Socket wrench set
• Large pliers (for the retaining ring)
• Empty gasoline container
• New fuel pump module (buy the complete assembly, not just the pump)
• New O-ring seal (must be replaced – do not reuse the old one)

Step 3: Remove the Fuel Tank

1. Raise the vehicle and support it securely on jack stands.
2. Place a container under the fuel tank drain plug (driver's side). Remove the plug and drain the fuel.
3. Loosen the clamp on the fuel filler hose and disconnect it from the tank.
4. Disconnect the two fuel lines from the pump. These are quick-release fittings – press the tab and pull apart. Label them so you know which is which.
5. Disconnect the vapor hose on the rear of the tank.
6. Place a jack under the tank with a wood block for support. Remove the two fuel tank straps.
7. Lower the jack and carefully slide the tank out from under the car.

Step 4: Replace the Fuel Pump

1. Wipe the top of the tank clean to prevent dirt from falling inside.
2. Use large pliers to turn the fuel pump module retaining ring counterclockwise. Remove the ring.
3. Carefully lift the fuel pump module out of the tank. Angle it slightly to avoid damaging the fuel level sending unit arm.
4. Insert the new fuel pump module. Make sure the tab on the module aligns with the notch in the tank.
5. Install a new O-ring seal (lightly oil it with clean engine oil first). Hand-tighten the retaining ring, then use pliers to snug it firmly. Do not overtighten – this can crack the plastic module .

Step 5: Reinstall the Tank

1. Slide the tank back under the car and raise the jack to position it.
2. Reinstall the fuel tank straps and tighten the bolts.
3. Reconnect the fuel lines (press them on until they click). Reconnect the vapor hose and the fuel filler hose.
4. Feed the electrical connector for the pump through the hole in the trunk floor and plug it into the wiring harness.

Step 6: Prime the System and Test

1. Turn the ignition to the "ON" position (do not start the engine). Listen for the pump to hum for 2-3 seconds. Turn the key off. Repeat this cycle 3-4 times to prime the system .
2. Start the engine. Check for fuel leaks under the car.
3. Replace the fuel cap and take the car for a test drive.

What Parts Do You Need for a 1998 Chrysler Cirrus Fuel Pump?

For a 1998 Chrysler Cirrus, you need a complete fuel pump module assembly. The direct OEM part number is R4778198 (Mopar) . This module includes the pump, fuel level sending unit, fuel pressure regulator, and strainer.

Aftermarket alternatives that fit the 1998 Cirrus (2.0L, 2.4L, and 2.5L engines) include the BDFHYK electric fuel pump module assembly, which replaces OEM numbers 4764184, 4778198, 4798947, and others . This is a direct replacement that includes everything needed for a complete swap.

Important: Do not just replace the pump itself. Replace the entire module. The module includes components like the fuel level sending unit and the fuel inlet strainer. Reusing an old sending unit or strainer with a new pump is a recipe for a repeat failure .

Tips for a Successful DIY Fuel Pump Replacement

• Always replace the O-ring seal. The O-ring that seals the pump assembly to the tank is a wear item. Skipping a new one causes leaks and fuel odor inside the cabin .
• Label the fuel lines. The fuel supply and return lines are different. If you mix them up, the engine will not run correctly .
• Use a torque wrench on the retaining ring. Overtightening can warp the sealing surface or crack the plastic module. Follow the manufacturer's torque specification .
• Replace the fuel filter at the same time. If your 1998 Cirrus has an external in-line fuel filter, replace it. A clogged filter puts extra strain on a new pump .
• Do not run the tank low often. Repeatedly running the fuel tank low or driving with a clogged filter shortens fuel pump life .

When to See a Professional Mechanic

While many DIYers can handle this job, there are times when you should call a professional. Stop DIY work and contact a certified mechanic immediately if any of the following apply:

• You smell fuel, burning insulation, or see smoke.
• The engine overheats, stalls repeatedly, or misfires under load.
• You are missing required tools, torque specs, or safe lifting equipment.
• You are not confident in the next step or safety outcome .

A professional mechanic can complete the replacement in 1-2 hours, while a DIY job typically takes 2-4 hours .

Final Thoughts

Replacing the fuel pump on a 1998 Chrysler Cirrus is a job that any competent DIYer can handle with the right preparation and tools.
