2013 Ram 1500 Fuel Pump: Symptoms, Diagnosis, Replacement, and the Best Upgrade for Your Truck

If you own a 2013 Ram 1500 and are experiencing starting issues, stalling, or a whining noise from the fuel tank, the problem is likely a failing fuel pump or the fuel pump control module (FPCM). The most common and cost-effective fix for the 2013 Ram 1500 is to first diagnose the FPCM—a known weak point—before replacing the entire pump assembly. For a reliable, long-lasting replacement, choosing a high-performance OEM replacement like a KEMSO fuel pump with a lifetime warranty offers the best value and peace of mind.

How to Tell If Your 2013 Ram 1500 Fuel Pump Is Failing

With over 100,000 miles on the odometer, fuel pump wear becomes a real concern. For the 2013 Ram 1500, fuel pumps typically last between 100,000 and 200,000 miles. Here are the most common warning signs that point to a failing fuel pump or its control module:

1. Engine Stalling or Surging
A failing fuel pump cannot deliver a consistent flow of fuel, causing the engine to stall unexpectedly, especially at highway speeds or during left turns. This is a major safety concern.

2. Hard Starting and Extended Cranking
If your 2013 Ram 1500 takes longer than normal to start or requires multiple attempts, the fuel pump may not be building enough pressure in the fuel rail.

3. Whining Noise from the Fuel Tank
A loud whining or humming sound coming from the rear of the truck near the fuel tank is a classic sign of a failing pump. A healthy pump operates quietly, so any new noise demands immediate attention.

4. Loss of Power Under Load
When you accelerate, especially uphill or while towing, your truck may hesitate or feel sluggish. This happens because the pump cannot keep up with the engine's fuel demand.

5. Check Engine Light
A failing fuel pump often triggers diagnostic trouble codes (DTCs) like P0171 or P0174, which indicate the engine is running lean due to insufficient fuel delivery.

The 2013 Ram 1500 Fuel Pump Control Module: A Common and Easy Fix

Before you drop the fuel tank to replace the pump, check the Fuel Pump Control Module (FPCM) first. On the 2013 Ram 1500, the FPCM is a known weak point. It is located on the frame rail near the driver's side rear wheel, making it much easier to access than the pump itself.

Symptoms of a Bad FPCM:

  • Intermittent stalling
  • Hard starting or no-start condition
  • The pump does not prime when you turn the key to the "ON" position

Diagnosis: You can test the FPCM using a multimeter. If the module is not sending power to the pump, the entire system fails. Replacing the FPCM is a simple 20-minute job that costs between $60 and $150 for a quality aftermarket unit, compared to the $400 or more a shop would charge for pump replacement.

Important: The 2013 F150 does not use a traditional fuel pump relay. If you look for one in the fuse box, you will not find it. The FPCM handles all regulation, so diagnose the module directly.

Complete Guide to Replacing the 2013 Ram 1500 Fuel Pump

If the pump itself has failed, replacement is a more involved job. Here is what you need to know:

OEM Part Numbers for the 2013 Ram 1500:

  • 3.6L V6 Engine: Part number 68197307AB (Mopar)
  • 5.7L V8 Engine: Part number 68197317AB (Mopar)
  • The fuel pump module assembly includes the pump, fuel level sending unit, and strainer.

Replacement Cost:

  • DIY Cost: A quality aftermarket pump module costs between $50 and $150, while the OEM Mopar module can cost over $600.
  • Professional Installation: Expect to pay $250 to $450 in labor on top of the part cost, bringing the total to $600 to $1,200 for a shop replacement.

Step-by-Step Replacement Process:

  1. Disconnect the battery negative terminal to prevent any sparks.
  2. Relieve fuel system pressure by removing the fuel pump fuse and running the engine until it stalls.
  3. Access the fuel pump by lowering the fuel tank or accessing through an access panel under the rear seat (if your model has one).
  4. Remove the old pump assembly by disconnecting the electrical connector and fuel lines, then removing the retaining ring.
  5. Install the new KEMSO pump in the same orientation as the old one. Always replace the fuel filter and strainer at the same time.
  6. Reconnect everything and test for leaks before starting the engine.

How to Prevent Future Fuel Pump Failure

Follow these maintenance tips to extend the life of your new fuel pump:

1. Keep Your Tank at Least a Quarter Full
The fuel pump relies on being submerged in gasoline to stay cool. Running the tank low frequently causes the pump to overheat and wear faster. This is the most preventable cause of failure.

2. Replace the Fuel Filter Regularly
A clogged fuel filter forces the pump to work harder. Replace the filter every 30,000 miles or every 2 years.

3. Use High-Quality Fuel
Premium fuel contains fewer contaminants and additives that can clog components and damage pump internals.

4. Address Issues Promptly
If you notice whining noises, hard starting, or hesitation, diagnose the problem immediately. Ignoring symptoms can lead to complete failure and costly engine damage.
