1999 Chrysler Town and Country Fuel Pump: The Complete Owner’s Guide to Symptoms, Replacement, and Cost
The bottom line: If your 1999 Chrysler Town and Country is hard to start, stalls on the highway, or makes a whining noise from the rear of the vehicle, the fuel pump is likely failing. Replace it as soon as possible to avoid getting stranded. A professional replacement costs between $400 and $1,200 depending on parts and labor, while a DIY job using a quality aftermarket pump can be done for under $150 in parts. The fuel pump is located inside the fuel tank, so replacing it requires dropping the tank or removing the pump module from the top.
Why the 1999 Chrysler Town and Country Fuel Pump Fails
The 1999 Chrysler Town and Country uses an in-tank electric fuel pump that sits inside the fuel tank. Over time, the pump wears out for several reasons:
Normal wear and tear – The pump runs constantly whenever the engine is on. After 20+ years, the electric motor inside the pump wears down, bearings fail, and the pump loses the ability to build proper pressure.
Contaminated fuel – Dirt, rust, and debris in the fuel tank can clog the pump’s inlet screen or damage the internal components. This is common on older vehicles that have not had regular fuel filter changes.
Overheating – Running the tank low on fuel frequently can cause the pump to overheat, because the fuel inside the tank helps cool the pump. A hot pump fails faster.
Electrical issues – A failing fuel pump relay, corroded wiring, or a blown fuse can prevent the pump from getting power. In some cases, the pump is fine but the electrical system is not delivering voltage to it.
Key Symptoms of a Bad Fuel Pump in a 1999 Town and Country
Before you spend money on a new pump, make sure the fuel pump is actually the problem. Here are the most common symptoms for this specific vehicle:
1. Engine cranks but will not start – This is the most obvious sign. If the engine turns over but never fires, the fuel pump may not be delivering fuel to the injectors. A quick way to test this is to spray starting fluid into the throttle body. If the engine starts briefly and then dies, you have a fuel delivery problem.
2. Loss of power on hills or under load – A weak pump cannot maintain pressure when the engine demands more fuel. You may notice the van struggling to accelerate or losing power when climbing a hill.
3. Whining noise from the fuel tank – A healthy fuel pump makes a quiet humming sound. If you hear a loud whine or a high-pitched screech coming from the rear of the van, the pump bearings are failing.
4. Surging or hesitation – The engine may buck or surge while driving at steady speeds. This happens when the pump delivers inconsistent fuel pressure.
5. Check engine light – The powertrain control module (PCM) will set a diagnostic trouble code (DTC) if it detects low fuel pressure. Common codes include P0087 (fuel rail pressure too low) or P0230 (fuel pump primary circuit malfunction).
How to Test the Fuel Pump Before Replacing It
Before you drop the fuel tank, run a few simple tests to confirm the pump is the problem. A diagnosis can save you from buying parts you do not need.
Test 1: Listen for the pump – Have a helper turn the key to the ON position (do not start the engine). You should hear a 2-3 second hum from the fuel tank area. If you hear nothing, the pump is not getting power or has failed.
Test 2: Check the fuel pump fuse and relay – On the 1999 Chrysler Town and Country, the fuel pump fuse is #16 (20 amp) in the underhood fuse box, also called the Power Distribution Center. Use a test light or multimeter to check for power at terminal 30 of the fuel pump relay socket. If the fuse is blown, replace it and see if the pump runs. If the fuse blows again, the pump is shorted internally and must be replaced.
Test 3: Fuel pressure test – Connect a fuel pressure gauge to the test port on the fuel rail. The 1999 Town and Country with a 3.3L or 3.8L engine should have 48-52 psi of fuel pressure at idle. If the pressure is below 30 psi or drops quickly after the engine shuts off, the pump is weak or the check valve is failing.
Test 4: Starting fluid test – Disconnect the intake air duct from the throttle body. Spray a short 1-2 second burst of starting fluid into the throttle body. Reconnect the duct and have a helper crank the engine. If the engine starts and runs for a few seconds, then dies, you have a fuel delivery problem.
1999 Chrysler Town and Country Fuel Pump Replacement Cost
The cost to replace the fuel pump on a 1999 Town and Country varies depending on who does the work and which parts you choose.
Parts cost – A new fuel pump module for the 1999 Town and Country typically costs between $58 and $150 for aftermarket brands. An OEM pump from Chrysler can cost $200-$350. The fuel pump module includes the pump, sending unit, and float assembly. You may also need a new fuel filter, which costs about $32.
Labor cost – Independent shops charge $180 to $700 for labor, while dealerships charge $500 to $1,000. The labor is relatively high because the fuel tank must be lowered or removed to access the pump.
Total replacement cost – At an independent repair shop, expect to pay $400 to $900. At a dealership, the total is $800 to $1,500.
DIY cost – If you do the job yourself, the pump module costs $58-$150. You will also need basic tools: a 10mm and 15mm wrench or socket, a strap wrench for the lock ring, vice grip pliers, and a jack to support the fuel tank. Total cost for a DIY job is under $200.
Step-by-Step Guide to Replacing the Fuel Pump on a 1999 Town and Country
If you are comfortable working on cars, you can replace the fuel pump yourself. This job takes about 2 hours for an experienced DIYer. Here is the process based on step-by-step instructions for 1996-2002 Caravan, Voyager, and Town and Country models.
Step 1: Relieve fuel system pressure – Remove the fuel pump relay from the underhood fuse box. Crank the engine several times until it fails to start. This releases the pressure in the fuel lines. Disconnect the negative battery cable.
Step 2: Prepare the vehicle – Jack up the rear of the van and place it on jack stands. If the fuel tank is full, drain it into a fuel-safe container. You will need to lower the tank, so the less fuel inside, the lighter and easier it is to handle.
Step 3: Lower the fuel tank – Place a jack and a block of wood under the fuel tank to support it. Remove the two 15mm strap bolts that hold the tank in place. Slowly lower the tank about 1.5 inches to access the fuel pump and filter assembly on top of the tank.
Step 4: Disconnect the fuel lines and electrical connector – Disconnect the two fuel lines from the pump by squeezing the plastic inserts and pulling the lines back. Have a catch pan ready for the fuel that will drip out. Unplug the electrical connector by releasing the locking tab and sliding the connector off.
Step 5: Remove the old pump – Clean off any dirt or debris from the top of the pump assembly. Use a strap wrench to unscrew the plastic lock ring that holds the pump in place. Lift the pump module out of the tank. Angle it toward the front of the van to clear the tank opening.
Step 6: Install the new pump – If the new pump does not have the float assembly attached, transfer the float from the old pump. Slip the new o-ring onto the pump. Install the new pump into the tank, making sure to align the protrusion on the pump with the notch in the tank. Tighten the lock ring using the strap wrench. Plug in the electrical connector and snap the two fuel lines into place.
Step 7: Reinstall the fuel tank – Raise the tank back into position, but stop about 1/4 inch from the top so you can start the strap bolts. Start the 15mm strap bolts, then raise the tank the rest of the way. Tighten the strap bolts securely.
Step 8: Test the system – Reconnect the negative battery cable. Turn the key to the ON position and listen for the pump to prime. Check for fuel leaks at the hose connections. Start the engine and verify fuel pressure is within spec.
Important Tips for a Successful Fuel Pump Replacement
Use a new o-ring – The o-ring on the lock ring creates a seal between the pump and the tank. Always use the new o-ring that comes with the pump. If the o-ring shifts during installation, the seal will leak fuel and you will have to drop the tank again.
Replace the fuel filter – The fuel filter is located on top of the fuel tank, right next to the pump. Since you are already dropping the tank, replace the filter at the same time. A clogged filter can cause the new pump to fail prematurely.
Check the wiring harness – On some models, the wiring harness connector at the pump can corrode or melt. If the connector looks damaged, replace it while you have access to the tank.
Do not run the tank low – After the new pump is installed, try to keep the fuel tank above 1/4 full. This helps the pump stay cool and extends its life.
Why Aftermarket Fuel Pumps for the 1999 Town and Country Are a Smart Choice
Some mechanics recommend using only OEM (factory) fuel pumps, but many aftermarket pumps are just as reliable and cost significantly less. Aftermarket pumps from reputable brands are built to the same specifications as the original equipment.
The aftermarket fuel pump for the 1999 Chrysler Town and Country with a 3.3L or 3.8L engine delivers 40-50 GPH (gallons per hour) free flow and 80-90 max pump PSI. It is a 12-volt electrical pump designed for gasoline engines. Many aftermarket pumps come with a lifetime warranty, which is better than the standard OEM warranty.
When choosing an aftermarket pump, look for one that includes the sending unit, float, and all necessary seals. This is called a fuel pump module. Replacing the entire module is easier and more reliable than replacing just the pump itself.
