1999 Plymouth Prowler Fuel Pump: Complete Guide to Symptoms, Replacement, and the Best Upgrade
If you own a 1999 Plymouth Prowler and your car is hard to start, stalls while driving, or loses power during acceleration, the fuel pump is the most likely culprit. The 1999 Prowler came with a more powerful 3.5L aluminum-block V6 engine producing 253 horsepower, and it relies on a properly functioning fuel pump to deliver the correct fuel pressure and volume to the engine. Replacing a failing fuel pump with a high-quality aftermarket unit, such as a KEMSO fuel pump, is the most reliable way to restore your Prowler's performance and avoid being stranded. This guide covers everything you need to know about the 1999 Plymouth Prowler fuel pump, including symptoms of failure, replacement options, and why KEMSO is the best choice for your vehicle.
Understanding the 1999 Plymouth Prowler Fuel System
The 1999 Plymouth Prowler is a retro-styled two-seat roadster that was produced by DaimlerChrysler. It uses an in-tank electric fuel pump that sits inside the fuel tank. The fuel pump is responsible for drawing fuel from the tank and delivering it to the engine's fuel injection system at the correct pressure. When the pump starts to fail, the engine does not get enough fuel, which leads to driveability problems.
The 1999 model year is significant because it received a more powerful engine compared to the 1997 earlier version. The 3.5L SOHC V6 in the 1999 Prowler makes 253 hp at 6400 rpm, coupled with a 4-speed Auto-stick automatic transmission. This higher output engine demands consistent fuel delivery, making the fuel pump a critical component for performance.
Common Symptoms of a Failing 1999 Plymouth Prowler Fuel Pump
Recognizing the early warning signs of a failing fuel pump can save you from a breakdown. Here are the most common symptoms that Prowler owners should watch for:
1. Hard Starting
If your Prowler cranks but takes longer than usual to start, or requires multiple attempts to fire up, the fuel pump may not be building enough pressure. A weak pump struggles to push fuel to the injectors, making cold starts difficult.
2. Engine Sputtering or Surging
A failing fuel pump delivers inconsistent fuel flow. This causes the engine to sputter at highway speeds, especially when you accelerate. You might also feel the car surge forward as the pump temporarily delivers more fuel.
3. Loss of Power Under Load
When you need to accelerate quickly, such as merging onto a freeway, a failing fuel pump cannot keep up with the demand. The engine may feel sluggish or lack power. This is a classic sign that the pump is weak.
4. Stalling
If the fuel pump stops working entirely while driving, the engine will stall. In some cases, the car may restart after cooling down, but this is a serious safety concern. Stalling can happen unexpectedly, especially in stop-and-go traffic.
5. Whining Noise from the Fuel Tank
A healthy fuel pump makes a quiet humming sound. If you hear a loud whining or buzzing noise coming from the rear of the car, especially near the fuel tank, the pump is likely wearing out. This noise means the pump is working harder than it should.
6. Check Engine Light
A failing fuel pump can trigger the check engine light. The car's computer may set diagnostic trouble codes related to fuel system pressure or fuel trim. Common codes include P0087 (Fuel Rail/System Pressure Too Low) or P0171/P0174 (System Too Lean).
What to Do If Your 1999 Prowler Has a Bad Fuel Pump
If you suspect the fuel pump is bad, the first step is to confirm the diagnosis. You can do this by checking the fuel pressure at the fuel rail using a gauge. The 1999 Prowler's fuel system should have a specific pressure range. If the pressure is low or drops quickly after the pump shuts off, the pump is likely failing.
Another step is to check the fuel pump relay and fuse. The fuel pump relay is a common failure point in older vehicles. A bad relay can mimic a failed pump. However, if the relay clicks and the pump still does not run, the pump itself is the problem.
Recalls and Safety Notes for the 1999 Prowler Fuel Pump
It is important to note that the 1999 Plymouth Prowler was subject to a recall related to aftermarket fuel pump modules, not the original equipment. The recall, issued by the NHTSA in 2006, involved certain Tigas brand fuel pump modules manufactured between June 1 and September 24, 2006. These aftermarket modules had a silicone flapper valve that was out of specification, which could swell and restrict fuel flow, leading to loss of power or engine stall.
This recall only applies to specific aftermarket replacement pumps, not the original pump that came with the car from the factory. If you are replacing your Prowler's fuel pump, make sure you choose a brand that does not have a history of such defects. KEMSO fuel pumps are built with high-quality materials and have a lifetime warranty, giving you confidence that the part is reliable.
How to Replace the Fuel Pump on a 1999 Plymouth Prowler
Replacing the fuel pump on a 1999 Prowler is a job that a moderately experienced DIY mechanic can handle, but it requires patience and the right tools. The procedure is similar to other Chrysler vehicles of the era.
Step 1: Safety First
Work in a well-ventilated area. Disconnect the negative battery cable to prevent sparks. Relieve the fuel system pressure by removing the fuel pump fuse and running the engine until it stalls. Wear safety glasses and gloves.
Step 2: Access the Fuel Pump
On the Prowler, the fuel pump is located inside the fuel tank. You will need to remove the rear trunk liner or access panel to reach the pump module. In some cases, you may need to drop the fuel tank. Support the tank safely before disconnecting any lines.
Step 3: Remove the Old Pump
Disconnect the electrical harness and the fuel lines from the pump module. Use a special tool to release the locking ring that holds the module in place. Carefully lift the module out of the tank. Be prepared for some fuel to spill.
Step 4: Install the New Pump
If you purchased a complete assembly from KEMSO, the installation is a direct swap. Install the new pump module into the tank, making sure the float arm is not bent. Replace the locking ring and tighten it securely. Reconnect the fuel lines and electrical harness.
Step 5: Test the System
Reconnect the battery. Turn the key to the ON position (without starting) to let the pump pressurize the system. Check for leaks at all connections. Start the engine and verify that the fuel pressure is within the correct range.
Step 6: Dispose of the Old Pump
The old fuel pump contains gasoline, which is hazardous waste. Take it to a recycling center or an auto parts store that accepts used parts.
