Is your Chevy Silverado displaying a dreaded C0267 code? This indicates a “Pump Motor Circuit Open” issue, often related to the fuel pump. A non-functioning fuel pump means your truck won’t start, leaving you stranded. This detailed guide will walk you through diagnosing and fixing this problem, empowering you to get back on the road. We’ll cover everything from basic troubleshooting to more advanced repair techniques.

Understanding the Chevy Silverado C0267 Code

The Chevy Silverado C0267 diagnostic trouble code specifically points to an open circuit within the fuel pump motor’s electrical system. This means the power supply to the fuel pump is interrupted, preventing it from operating. The open circuit could be anywhere along the electrical pathway, from the fuel pump itself to the vehicle’s power supply. Ignoring this code will leave your truck unable to start. Understanding the root cause is crucial for effective repair.

Common Causes of a C0267 Code

Several factors can trigger a C0267 code in your Chevy Silverado. These include:

• Blown Fuel Pump Fuse: This is one of the simplest and most common causes. A blown fuse interrupts the electrical flow to the pump.
• Faulty Fuel Pump Relay: The relay acts as a switch, controlling the power to the fuel pump. A malfunctioning relay will prevent the pump from receiving power.
• Damaged Wiring Harness: Wiring can become frayed, corroded, or damaged due to age, rodents, or physical impacts. A break in the wiring will disrupt the circuit.
• Defective Fuel Pump: The fuel pump itself might have failed, either due to wear and tear or internal damage.
• Faulty Fuel Pump Module: Some models incorporate a fuel pump module, which integrates the pump, electrical components, and other functions. A failure here can generate the C0267 code.

Step-by-Step Troubleshooting and Repair of Chevy Silverado C0267

Before you begin any repairs, always disconnect the negative battery terminal to prevent electrical shocks. Safety first!

Step 1: Check the Fuel Pump Fuse

Locate your vehicle’s fuse box (usually under the hood or inside the cabin). Consult your owner’s manual to identify the fuel pump fuse. Check if the fuse is blown (a broken filament will be visible). If blown, replace it with a fuse of the same amperage rating. This is often the simplest fix.

Step 2: Inspect the Fuel Pump Relay

Similar to the fuse, locate the fuel pump relay in the fuse box. You can usually swap relays with a similar one (not critical for the fuel pump) to see if the issue is resolved. If the swapping fixes the code, replace the faulty relay.

Step 3: Examine the Fuel Pump Wiring Harness

Carefully inspect the wiring harness leading to the fuel pump. Look for any visible damage, including frayed wires, corrosion, or broken connections. Repair any damaged wiring or replace sections of the harness as needed. This may require specialized tools and knowledge of automotive wiring diagrams.

Step 4: Test the Fuel Pump (Advanced)

Testing the fuel pump requires some specialized tools, such as a multimeter and potentially a fuel pressure gauge. You’ll need to access the fuel pump (usually located in the fuel tank), which might involve dropping the fuel tank. This step is more involved and should be done with caution and by someone with experience. Consult a repair manual for detailed instructions on fuel pump testing. You often need a fuel pump testing tool to test without removing the pump.

Step 5: Replace the Fuel Pump (if necessary)

If all other checks fail, the fuel pump itself may be faulty. Replacing the fuel pump is a more complex procedure and usually requires dropping the fuel tank. This is best left to experienced mechanics unless you are comfortable with advanced automotive repairs.

Advanced Troubleshooting for Persistent C0267

If you’ve completed the above steps and the C0267 code persists, more advanced diagnostics might be necessary:

Using a Scan Tool

A professional-grade scan tool can provide more detailed information about the fuel pump circuit, helping pinpoint the exact location of the problem. This tool can read live data and help isolate the issue rather than just the code.

Checking the Fuel Pump Module

In some Chevy Silverado models, the fuel pump module controls the pump’s operation, and a failure here could lead to the C0267 code. Testing this module often requires specialized tools and expertise.

Preventative Maintenance to Avoid C0267

Regular maintenance is key to preventing issues like the C0267 code.

• Regular Fuel System Inspections: Have a mechanic check your fuel system during routine maintenance to catch potential problems before they lead to major repairs.
• Quality Fuel: Use clean, high-quality fuel to minimize the risk of fuel pump contamination.
• Proper Vehicle Storage: If you’re storing your Silverado for an extended period, take measures to protect it from rodents and other potential damage to the fuel system.

Frequently Asked Questions (FAQ)

Q1: Can I drive my Chevy Silverado with a C0267 code? No, you should not drive your Silverado with a C0267 code. The lack of fuel delivery could cause engine damage.

Q2: How much does it cost to fix a C0267 code? The cost varies greatly based on the root cause. A simple fuse replacement might cost a few dollars, while a fuel pump replacement could be several hundred.

Q3: Is it difficult to replace the fuel pump myself? Yes, it’s a relatively complex repair involving dropping the fuel tank and can be challenging for those lacking experience with automotive repair.

Q4: How can I prevent future C0267 codes? Regular vehicle maintenance and using high-quality fuel can greatly reduce the risk of this problem.

Conclusion: Addressing Chevy Silverado C0267

The Chevy Silverado C0267 code, indicating a “Pump Motor Circuit Open,” can be frustrating but solvable. By systematically following the troubleshooting steps outlined above, you can often identify and fix the problem. Remember to always prioritize safety and consult a professional mechanic if you’re unsure about any step of the repair process. Early detection and preventative maintenance can save you time, money, and the inconvenience of a stranded vehicle.
